What are Vac-U-Lock Dildos?
Vac-U-Lock dildos are specially designed attachments featuring a hollow channel in the base that connects to a compatible Vac-U-Lock plug or adapter. Rather than being held in place by the O-ring found on many traditional strap-on harnesses, the attachment slides securely onto the Vac-U-Lock connector.
The major advantage of the system is interchangeability. Once you have a compatible harness, base or adapter, different Vac U Lock dildo designs can be swapped on and off without replacing the entire setup. This provides access to a wide variety of sizes, shapes, materials and styles within the same compatible system.
Why You'll Love Them
Vac-U-Lock systems are popular because they provide a simple and versatile way to use interchangeable compatible attachments.
- Interchangeable attachment system.
- Wide variety of dildo sizes and styles available.
- No traditional O-ring required on compatible systems.
- Attachments can be changed without replacing the harness.
- Compatible harnesses, adapters and accessories available.
- Useful for building a customised collection over time.
How to Choose the Right Vac-U-Lock Dildo for You
Start by confirming that the product is genuinely compatible with the Vac-U-Lock system. Although products from different categories can look similar, a conventional dildo or harness attachment will not necessarily fit a Vac-U-Lock connector.
Once compatibility is confirmed, compare the external dimensions, insertable length, diameter, material, firmness and overall shape. Vac-U-Lock dildos are available across a broad range of sizes, so checking the actual measurements is more useful than relying on product photographs alone.
If you're purchasing your first product in the system, also check whether you're buying only the attachment or whether a Vac-U-Lock plug, harness or compatible base is included. Individual product pages will explain exactly what comes with each item.

Tips for Best Use
Before attaching a Vac-U-Lock dildo, confirm that both components are designed for the same connection system. Follow the manufacturer's instructions for fitting the attachment securely onto the Vac-U-Lock plug and check that it is properly seated before use.
A small amount of suitable lubricant may make attaching and removing some Vac-U-Lock products easier, but always check the manufacturer's recommendations and material compatibility first. Avoid forcing an attachment onto a connector if it does not appear to fit correctly.
After use, remove and clean the attachment according to the manufacturer's instructions. Pay particular attention to the hollow Vac-U-Lock channel and allow all components to dry completely before storage.

FAQs
Who makes Vac-U-Lock dildos?
Vac-U-Lock is closely associated with Doc Johnson, one of the best known manufacturers in the adult products industry. Doc Johnson offers a large range of Vac-U-Lock dildos, harnesses, plugs and compatible accessories designed around the interchangeable Vac-U-Lock connection system. This extensive range is one of the advantages of choosing Vac-U-Lock, as customers can build on an existing compatible setup by adding different Doc Johnson attachments over time. Always check the individual product description for compatibility before purchasing.
How does the Vac-U-Lock system work?
The system uses a specially shaped Vac-U-Lock plug or connector that fits inside the hollow channel of a compatible attachment. The attachment is pushed onto the connector until securely positioned. When you want to change products, the attachment can be removed and another compatible Vac-U-Lock dildo fitted to the same connector.
What is the difference between Vac-U-Lock and an O-ring harness?
An O-ring harness generally holds a compatible dildo by positioning its base through a circular ring at the front of the harness. A Vac-U-Lock system instead uses a plug that fits inside a specially designed channel within the attachment. Both systems allow compatible products to be changed, but they use fundamentally different attachment mechanisms.
Can any dildo be used with Vac-U-Lock?
No. A product needs the appropriate hollow Vac-U-Lock channel or compatible connection design to fit the system correctly. A conventional solid dildo cannot simply be attached to a Vac-U-Lock plug unless it has specifically been designed or adapted for that connection system.
Why choose Vac-U-Lock instead of a traditional strap-on dildo?
The main advantage is interchangeability. Once you have a compatible harness or mounting system, you can choose from different Vac-U-Lock dildo sizes and styles without purchasing another complete harness. Some users also prefer the plug based connection because it avoids the need to match a dildo base to a particular O-ring diameter.
