It’s very easy to use and suits best with small dildos, it gets a bit unstable when using heavier dildos. Great for a newbie to explore pegging and other kinds of strap on play.

Need a Dildo for Your Vac-U-Lock Strap-On?
It’s not always that you buy a vaculock strap on that comes with a compatible dildo. And the vac u lock system is a bit tricky in that way, not all strap on compatible dildos are possible to use. We’ve actually written a post about the best vac-u-lock attachments‘ too. But anyway, here are a few recommendations for you who want to add a dildo.

What is Vac-U-Lock?
Vac-u-lock is an attachment system developed by Doc Johnson to create secure strap on play. It’s a two-part system, one adapter that is placed on the harness and one adapter placed inside the dildo. When these are attached you insert the harness adapter inside the dildo adapter and it will create a vacuum suction that makes it remain stable. This allows wild and crazy, but still safe, strap on play!
How to use a vac-u-lock strap on?
It’s not difficult to use a vac-u-lock strap on and neither does it take long time to put it on, let’s step by step see how it’s done:
Insert the plug
First you need to insert the plug into your vac-u-lock strap on harness. It might look a bit different depending on which one you have.
Powder it!
This is not for all vaculock strap on dildos, but for some of them you need to powder the inside to be able to attach the plug, otherwise it will be too much friction.
Attach it!
You need to attach the dildo to the plug, this is done be twisting it/wiggling it, or just firmly pressing the hole. This is done until the vacuum has created a suction and is attached close to the harness.
Buckle up!
Now it’s time to put on your harness and adjust the straps until you feel it close to your body and comfortable enough to do some thrusting.
How to clean a vac u lock strap on?
It all depends on which one you have bought, we recommend you read the user manual before cleaning, or even using, it. If you don't have it, check what material it's made from both the harness and the strap on, see if there are any electronic functions that you need to be aware of and then follow our guide below.
