About the Vac-U-Lock range

Everything here shares one base so parts mix and match. The dildos come in several materials and styles: dual density Ultraskyn in thin, hung and standard sizes, the Codeblack versions of the same shapes, The Naturals thin and double penetrator, Crystal Jellies, Realistic Stryker, Perfect Erect, Kong Firmskyn and Raging Hard-Ons, plus smooth, G-spot and spiral silicone dildos. The fantasy group covers the Red Raider, Outer Rim, Milky Way, Green Serpent, Dragon's Tongue, Celestial Unicorn Horn and a travel-size tentacle, some of them glow in the dark. Harnesses include the Ultra Harness with snaps or plug, the Supreme Harness with vibrating plug and remote, and the Platinum Supreme, Luxe and Corset harnesses with butt plug. Starter sets pair a classic, realistic or Ultraskyn dildo with the Ultra Harness. Accessories include a vibrating plug with wireless remote, and the thrusting sex machine sits at the premium end. Prices run from entry-level jelly dildos to a premium machine.

How to choose from Vac-U-Lock

Start with the harness, then choose a dildo to suit the receiver.

  • First strap-on: the Ultra Harness set with a classic or realistic dildo keeps the cost down.
  • Comfort for the wearer: the Supreme or Platinum harnesses add a plug or vibrating plug for the person strapping on.
  • Realism: Ultraskyn or Codeblack dual density dildos feel softest on the outside with a firm core.
  • Something playful: any fantasy dildo locks onto the same plug.

FAQs

Vac U Lock: frequently asked questions

What does Vac-U-Lock make?

Vac-U-Lock is Doc Johnson's interchangeable system of dildos and harnesses. It makes realistic Ultraskyn and Codeblack dildos, jelly, silicone and fantasy dildos, double penetrators, Ultra and Platinum harnesses with plugs, vibrating remote plugs and a thrusting sex machine that all share one locking base.

Which Vac-U-Lock product is good for beginners?

The Classic Dildo with Ultra Harness set is the simplest entry: a basic harness and a mid-sized dildo in one box. The Naturals Thin or Ultraskyn Thin dildo suits a receiver who wants a slimmer start. Add lubricant and go slowly.

How do I care for Vac-U-Lock products?

Wash dildos with warm water and toy cleaner before and after use, including inside the hollow base, and dry fully. Use water-based lube with silicone and Ultraskyn. Store Ultraskyn and jelly dildos separately with a light dusting of renewing powder if supplied. Hand wash harnesses and air dry.
