Intro

Vac-U-Lock is Doc Johnson's attempt at making an attachment compatible system for Sex toys.

Every toy comes equipped with a hole in their base and the attachments are made to plug into that said hole.
The shape of the plug causes a vacuum once inserted and should be very stable during use.

And while Doc Johnson used to be the only company offering vac-u-lock attachments and toys, a lot of third-party companies have jumped on the bandwagon throughout the years.

It has even become the standard attachment for most Fuck Machines available today.

Sadly, there isn't much information out there on the subject. This is why we're excited to bring you this guide today.
So throughout the course of this article, we'll cover the best vac-u-lock toys as well as the best vac-u-lock attachments the world has to offer.

Dildo dealer pro-tip #1: Using a bit of water-lube will make inserting and removing your inserts a whole lot easier.

Dildo Dealer Pro Tip #2: When removing your Vac-U-Lock attachments, try tilting the accessories on the side to break the vacuum instead of pulling straight on.


Also, make sure to see our guide on what lubes to use as well as how to clean your toys to avoid any complications.


That being said, here’s list of the best Vac-U-Lock Attachments & Toys, not necessarily from worst to best, because everyone’s needs and budgets are different.

Best Vac-U-Lock Toys

 

Official Vac-U-Lock Toys

Doc Johnson offers plenty of dildos for their vac-u-lock system, sadly most of them aren't body-safe and come in porous and impossible to sanitize materials.
So avoiding their UR3 and jelly toys is essential if you want to keep your nether regions happy.

With that being said, they do offer a few silicone options that are entirely safe to use.

And as always, don't use the refresh powder they give you, there's no reason you should use that on any silicone toy and it's a bit of a weird move on their part.
Although it can be used to make inserting and removing your attachments easier if put some inside of the hole, it is by no means a "refresh powder" for silicone.

Doc Johnson's Platinum Collection

vac u lock attachments

This is the biggest official collection of body-safe Vac-U-Lock toys.

They offer very realistic dildos as well as more abstract ones and it is usually the best place to start when looking for toys for your Vac-U-Lock Attachments.

The platinum-cured silicone they feature is a bit on the firmer side but it shouldn't be much of a problem for most people.

Unofficial Vac-U-Lock Toys

While the official toys are pretty swell and all, you can never have too much choice when it comes to sex toys since everyone's needs are different.

Third-party companies also offer a level of quality and variety that you won't find in Doc Johnson's budget options mentioned above.

So whether you're looking for ultra-realistic, fantasy or very large toys, there's bound to be something for you.

RealCock 2 by Abyss Creations

vac u lock attachments

From the makers of the uncanny and luxurious RealDolls comes the most realistic dildo ever made.

The two layers of silicone found on these act like any other dual-density blend, with one big difference: 
The second layer is not attached to the first, acting like a realistic layer of skin that's slides up and down as you thrust.

Foreskin lovers shouldn't get too excited though since the RealCock 2 acts more like a circumcised penis than a pristine one.

Mr. Hankey

Large sex toys

On top of selling traditional large realistic dildos, Mr. Hankey also hold plenty of fantasy options that would give Bad Dragon penis envy.

And if you're looking for large sex toys, they offer some of the largest silicone toys you will ever find. 
Of course, most of their toys come in multiple sizes, so if you're looking for something a little smaller, they got you covered as well.

Almost all their toys come with a Vac-U-Lock hole, just double check the product description to make sure it is the case.

SquarePegToys®

Large sex toys

SquarePegToys® offer some of the largest silicone dildos you can find today.

And you'll get to pick between either their super squishy and gorgeous bronze or graphite silicone or their firmer black silicone, with some toys offering more traditional colors as well.

Just don't forget to select the SquarePegHole™ option on your toy of choice when ordering.

Other Non-Vac-U-Lock Toys

While your level of success might vary from model to model, a lot of dildos with vibrating bullet holes will work with the Vac-U-Lock system.

It is worth noting that the traditional bullet holes found on most toys are a bit smaller than the Vac-U-Lock Holes.

But back at the shop, we've had a varying level of success with some vibrating Tantus toys, as well as some of Vixen Creations vibrating toys.
This solution usually works better with less rigid silicone blends.

Of course, the size of the holes will make insertion a bit more difficult, but with a bit of water-based lube, you should be able to make them fit without too much work.

The Vac-U-Lock attachments will also stretch out the toys and make them bulge out at the base a little bit, but most silicone toys can handle quite a bit of stretching without tearing.

This wasn't stress tested through time and you might end up breaking your toy over extended use.

It is by no means an optimal solution, so use this knowledge at your own risk.

Otherwise, toys with no holes at all still can be converted into Vac-U-Lock compatible toys if you're a little handy.
Just make sure to practice on a cheap toy if you don't want to ruin your favorite high-end dildo.

 


Best Vac-U-Lock Attachments

 

Vac-U-Lock Harnesses

If you're planning on getting a Vac-U-Lock Harness, there are plenty of options to pick from.

The Biggest advantage with these harnesses is that they're some of the most stable options in the strap-on world.
This is because the Vac-U-Lock adapter leaves no room for wiggling around like most classic O-Ring systems.

And in general, they're all pretty cheap, which is a big plus for people starting out.

That being said, The Vac-U-Lock Harness system is by no means perfect.
You see, the square base on every Vac-U-Lock Adapter might become a little uncomfortable over extended and/or rough play.

But if you replace the adapter with a Vac-U-Lock Suction cup, nothing stops you from using regular universal O-ring harness.

So unless you enjoy a bruised up pubic bone, you might want to invest in a comfortable (but more expensive) Strap-on like the great Joque harnesses.

 

Supreme Harness by Doc Johnson

vac u lock harness

Like I mentioned before, almost every model they offer is pretty cheap, therefore great for starting out.
But If you ever want to use any other toy that isn't Vac-U-Lock compatible, you're out of luck.

Well not with these harnesses since they do the Vac-U-Lock system in tandem with the traditional O-Ring system.
So whether you want to use your Vac-U-Lock toys or any other dildo with a base, you're set.

This makes this harness the best Vac-U-Lock Strap-On you can get today.

It's unisex and is the most comfortable harnesses in the collection in part due to the back support that won't dig in your skin as you thrust.

The kit comes with a Vac-U-Lock Adapter, Differently Sized O-Rings and plenty of strap-length so it can fit on bigger girls as well ( we suggest cutting the straps to your desired length if you don't want them dangling about ).

Vac-U-Lock Accessories

Doc Johnson offers a wide range of Vac-U-Lock accessories, some being more useful than others.
So If you don't see it here, chances are they aren't really worth it ( We're looking at you E-Z rider ball ).

 

Vac-U-Lock Toy Holders

vac u lock attachments

If you want to make the handling of your dildos a bit more interesting, the basic handle is great and will make you feel like a sexy cock sword warrior. Jokes aside, the extension it gives makes it a great option for solo as well as couple play.

Otherwise, If you're feeling a little more aggressive, the Knuckle Duster Attachment should help to make your BDSM sessions a bit more interesting.

Another personal favorite is a double-ended connector. This Vac-U-Lock Attachment will let you connect two dildos of your choice together.
The great thing about this is that since everyone has their own personal tastes, you can really customize your double ended combo to suit each other's needs.

It's no mystery that we're big fans of the Magic-Wand and its alternatives.
This is why we'd like to give a shoutout to the Vac-U-Lock wand adaptor.
And since Vac-U-Lock systems offer a snug fit, you won't have to worry about vibrations not traveling throughout your toys. Which is a common issue with a lot of Wand attachments. 
Another big plus over the other plastic attachments is that this collaboration between Doc Johnson and Kink is entirely made of silicone.
This means it's completely sanitizable and it'll last you a long time!

 

Vac-U-Lock Suction Cups

vac u lock attachments

The Vac-U-Lock suction cups from Doc Johnson are a bit hit and miss.
Being a bit too rigid, they'll only work on very smooth surfaces, like glass, tiles, metallic surfaces and plastic.

And while they'll work pretty flawlessly on Horizontal surfaces, don't expect the same for walls and other vertical planes as the toys will tend to slide around on the surface before eventually coming off.

You can choose between their basic small suction cup that comes included with most kits or the larger model ( seen above ) that is supposed to work better with bigger toys.

Just avoid their deluxe suction cup, since it's a pretty flimsy and ineffective build. A real shame since, if done well, this could've been a great attachment.

And while the basic suction cup usually comes in boring old white, depending on where you shop, you can get a Black as well!

Bullet Vibrators

A big issue with the Vac-U-Lock hole is that it is too wide to fit traditionally shaped bullet vibes.
Most of them are just going to loosely rattle inside the hole and slip out. Which is a real shame, especially for fans of the amazingly rumbly Tango.

But once more, we've done all the research for you and know of a few alternatives that are going to fit beautifully with your favorite Vac-U-Lock toys.

 

Screaming-O Charged Vooom

Best bullet vibrator

If you're looking for a perfect entry level bullet vibrator, it doesn't get much better than this.
The Vooom is pretty much your traditional cheap portable bullet vibrator on crack.

It is rechargeable, virtually silent, has 3 incremental constant vibration modes as well as 7 rhythmic pulsations.
So compared to the only 1 to 3 Incremental vibrations you will find on most cheap bullets, this is already a big plus.

On top of that, the Vooom packs some pretty decent vibrations. And while it might not rumble like the high-end toys, it still has plenty of power and rumbles to please most folks.

But most importantly, it doesn't run on small shitty expensive watch batteries you have to replace every 30 minutes!
Just recharge it through USB and you're set.
So while you might spend 15 dollars less on a cheap standard bullet vibrator, the money you will save on batteries alone makes the Vooom pay for itself.

The only real issue we can find is that the button to control the toy is rather small.
So in the heat of the action, things can get a little clumsy when trying to crank up or stop your toy.

Sensuelle Point by Nu

Nu Bullet Vibrator

 

This is a great cheap alternative to the amazing Tango by We-Vibe.
It is almost as powerful with a ridiculous 20 functions.
It's rechargeable by electromagnetic induction and covered for 1 year by the company, just like it's higher-end counterpart.

A nice win over We-vibe's bullet is that the charger also acts as a stand. This way it is not just laying on its side like with We-vibe's magnetic charger. But it does reduce its portability on the go if you're carrying the charger with you.

Where it really looses against the Tango is that even though this bullet vibrator fares well in the shower it will likely die if used in the bath. The vibrations are still not completely on par either compared to the way the Tango shakes and gyrate when turned on.

It is also a bit thicker than the Tango and doesn't look as refined. But seeing the price difference, this shouldn't surprise you too much.

Also, a lot of people report that the charger stops working after a while. But back at the old sin bin, we've noticed that usually cleaning the metallic contacts on the bullet vibrator and the charger with rubbing alcohol does the trick at bringing it back from the dead.

Exposed Nocturnal Lipstick Bullet by Blush

best bullet vibrator

Now if you're the type of person who needs raw/borderline intolerable power, you will love the Exposed Nocturnal Lipstick.
This bullet vibrator is essentially the smallest wand you will ever find.

The Exposed Nocturnal Lipstick ( what a mouthful ) comes with 5 incremental vibrations as well as 5 patterns for a total of 10 modes.

It has a nice little metallic finish for a touch of glam. It's a design reminiscent of high-end lipsticks, hence the name.

And shaped in a similar way to the Tango, this little guy is even stronger than its cult classic counterpart. And at almost half the price of the Tango, it's quite a feat.
But all that strength comes at a price.
You see, instead of providing deep rumbles to rattle your bones, the vibrations are quite buzzy and surface level.
It also makes this bullet vibrator surprisingly noisy as well for such a small toy.

But all that power makes this clit vibrator a perfect toy for powering your toys with bullet holes.

So if you don't mind sacrificing rumbles for pure power, this toy will literally knock your socks off.
Otherwise, if you live for the rumbles, you're better off going with the Nu Sensuelle Point.

Vac-U-Lock Compatible Fuck Machines

Most Fuck Machines comes with Vac-U-Lock plugs as their standard attachment.

With these, you will get more strokes per minutes and more torque than you could ever ask for.
And if you're in a relationship, sex machines are perfect threesome third wheels.

Through the course of this entry, we'll cover compact and cheaper models, a DIY hack, as well as full-size and feature packed sex machines.
So whether you have 150$ or 4000$ there's bound to be something for your drawer, closet or sex dungeon!

 

DIY Power Tool Mod Sex Machine

Hands free sex toys for women

If you can't afford a sex machine or you mostly intend on playing with a partner, this is an awesome, powerful and dirt-cheap option.

But if you want to ride solo or you're looking for better stroke length, this isn't the best choice.

 

KTM Fuck Machines

Best Fuck machines

KTM offers some of the best machines and prices in the industry. They also carry the biggest variety of quality machines we've ever seen.

All machines come with adjustable stroke length and you can also expect 6 to 7 inches of maximum stroke depth depending on the machine.
The cheaper models can rock a good 200 strokes per minutes and their best machine can go as fast as 268 RPMs without breaking a robo-sweat.

And KTM doesn't stop at making amazing fuck machines either, they also make a multitude of great accessories and attachments.

 

F-Machine

hands-free sex toys for women

If you live in the U.K. and want to avoid the shipping and handling from KTM, a better option would be to go with F-Machine.

The Gigolo, their cheaper model features 240 strokes per minute and 1 to 4 inches of stroke length.

The Pro II, their flagship model, has just as many strokes per minutes as the gigolo but offers 1 to 6 inches of stroke length with just enough torque to handle bigger toys as well.

F-Machine might not have all the options and crazy performances you can get from KTM machines, but it offers sleek, quality devices that should please most.

 

Hismith Fuck Machine

hands-free sex toys for women

We usually never push Chinese made, amazon toys. But you can consider this sex machine one of the rare exceptions.
If you live in some parts of Europe, Asia or Australia, it might also be the only decent machine you can get without spending an arm and a leg on shipping.

You can expect about 240 strokes per minutes and 2 to 6 inches in stroke length and there's also plenty of attachments and accessories to choose from.

 

Shockspot Sex Machines

hands-free sex toys for women

The Shockspots are simply the best sex machines available on the market today. They outperform and have more features than any other machine money can buy.

These luxury fuck machines offer speeds up to 24 inches per second and about a 105 pounds in torque.
The classic and Dual Thruster models offer 8 inches max in stroke length and there's a 12-inch capable machine as well.

One of our favorite features is that you can control the stroke length directly on the controllers with no needs to stop and interface with the machine itself.
These great machines also can be controlled by a PC, a remote control or even with your partners Fleshlight with the V-Stroker Attachment.
