Frequently Asked Questions
Are RealCock Vac-U-Lock dildos compatible with all Doc Johnson accessories?
Yes. RealCock Vac-U-Lock dildos use the standard Vac-U-Lock plug size and are compatible with all Doc Johnson Vac-U-Lock harnesses, suction plugs, machine attachments, and mounting accessories. They are also compatible with most third-party accessories that use the standard Vac-U-Lock socket size.
Can I use a Vac-U-Lock dildo without a harness?
Yes. Vac-U-Lock dildos can be used with a standalone suction cup Vac-U-Lock plug for hands-free mounting on flat surfaces. They can also be held by hand. The Vac-U-Lock plug does not interfere with manual use.
Do Vac-U-Lock RealCock dildos have the same silicone construction as standard models?
Identical. The only difference between our Vac-U-Lock models and suction cup models is the base design. The triple-layer platinum silicone body, Sil-Slide outer skin, and handcrafted anatomical detail are exactly the same across both base types.
How do I attach a Vac-U-Lock dildo to a harness?
Insert the Vac-U-Lock plug on the base of the dildo into the Vac-U-Lock socket on your harness or accessory. Press firmly until you feel it click into place. To remove, squeeze the socket ring and pull the plug out. No tools, no threading the entire process takes under five seconds.
