Vac-U-Lock is Doc Johnson's industry-standard interchangeable attachment system — a patented plug-and-lock mechanism that connects any Vac-U-Lock compatible dildo to any compatible harness, suction cup, machine, or handle. Once you invest in Vac-U-Lock, you can expand your collection indefinitely without buying new mounting hardware.
How Vac-U-Lock Works
Every Vac-U-Lock dildo has a hollow plug built into the base. This plug locks onto any Vac-U-Lock accessory — harness O-rings, suction cup mounts, Fleshlight adapters, sex machine attachments, and more — creating a secure, rattle-free connection. Pull to release, press to lock.
Vac-U-Lock Dildos
Hundreds of dildo options in realistic and non-realistic styles, all sizes and skin tones, in silicone, dual-density UR3, and more — all with the Vac-U-Lock plug built in.
Vac-U-Lock Harnesses & Mounts
Strap-on harnesses, suction cup bases, sex machine adapters, and standalone handle attachments. Each accessory opens up new ways to use your dildo collection.
Why Vac-U-Lock?
Every new dildo works with every existing mount. Every new mount works with every existing dildo. The most versatile and expandable system in adult toys.
