Perfect Fit Xact-Fit #20 Silicone Cock Rings 2 Pack 51mm

Two Matching 51mm Rings For A Roomier, More Precise Fit Without The Rigidity Of Metal

The Perfect Fit Xact-Fit #20 is for anyone who likes a properly sized cock ring but finds smaller diameters too restrictive. With a generous 51 mm internal opening and controlled silicone stretch, it offers a more defined fit than a typical one-size stretchy ring.

Both rings in this pack are identical #20 models, made from premium soft-touch silicone that balances firmness with enough flexibility for easier fitting and removal. You get noticeable support without committing to completely rigid hardware.

Each ring is stamped with its size, making it easy to identify your preferred fit. Use one as your regular ring and keep the second as a spare, rather than buying another assortment of sizes you may never use.

“A roomier 51mm fit, two matching rings and silicone that knows the difference between flexible and floppy.”

Perfect Fit Xact-Fit #20 Cock Ring Key Features:

✅ Two Identical #20 Rings: Both rings have the same 51 mm internal diameter, giving you two matching cock rings rather than a mixed-size assortment.

✅ Precision 51 mm Sizing: Each ring has an internal diameter of approximately 51 mm, or 2 inches, making it one of the roomier options in the Xact-Fit range.

✅ 160 mm Internal Circumference: The published circumference provides another useful measurement when comparing different Xact-Fit sizes.

✅ Controlled Silicone Stretch: The rings offer enough flexibility for fitting and removal without relying on the extreme elasticity of generic one-size designs.

✅ Premium Soft-Touch Silicone: Plush silicone provides a smooth, flexible surface against the skin while maintaining a substantial feel.

✅ Precision Sizing System: The wider Xact-Fit range uses nominal 0.1-inch increments, allowing you to move between closely spaced sizes rather than making large jumps.

✅ Size Stamped On Each Ring: Both rings are clearly marked #20, making identification easy when storing or comparing different sizes.

✅ Strong Silicone Construction: Perfect Fit designed the rings to combine durability with flexibility, offering a softer alternative to rigid metal.

✅ Stackable For Experienced Users: The rings can be combined, although wearing two increases constriction and should only be considered after becoming comfortable with a single ring.

Product Details

The Xact-Fit system is built around a simple idea: a few millimetres can make a real difference when choosing a cock ring. Instead of offering only small, medium and large options, Perfect Fit developed a range of closely spaced sizes to make finding the right diameter easier.

Size #20 measures approximately 51 mm internally, placing it between #19 at 48 mm and #21 at 53.5 mm. That makes #20 particularly useful when a smaller ring feels too restrictive but you still want a defined, supportive fit.

The silicone is intentionally firm yet flexible. Unlike highly elastic TPE rings that can expand significantly, Xact-Fit uses more controlled stretch so the starting diameter remains meaningful once the ring is positioned.

This pack includes two identical #20 rings. There is no smaller or larger alternative inside, making it especially practical for someone who has already established that a diameter around 51 mm suits their anatomy.

Best For

Best for someone who prefers a roomier cock ring and already knows that approximately 51 mm is a comfortable starting diameter. If you have tried Xact-Fit #19 and found its 48 mm opening a little too restrictive, moving up to #20 provides approximately 3 mm of additional internal diameter.

It is also an excellent choice for people who enjoy the predictability of precisely sized rings but prefer silicone over metal. You get more flexibility when fitting and removing the ring without losing the benefits of choosing a specific diameter.

The matching two-pack makes particular sense when you have already found your preferred size and want a spare rather than another sizing assortment.

Not Ideal For

Not ideal if you are completely unsure what cock ring size works for you. Both rings are #20, so there is no smaller alternative in the pack if 51 mm feels too loose or larger option if it feels too restrictive.

It is also not designed for people who want maximum adjustability. Although the silicone stretches, there is no slider, buckle or quick-release mechanism for changing the tension.

If smaller rings already feel loose, #20 may provide less constriction than you want. A larger starting diameter does not automatically mean a better fit, and the correct size should always be comfortably snug rather than excessively tight.
