Tantus Intermediate C-Ring 1.875 in. Onyx
The Tantus Intermediate C-Ring 1.875 in. Onyx is engineered for those who want precise constriction without compromising safety. Made from Tantus’s ultra-premium silicone, the C-ring’s broad band distributes pressure evenly, holding the testicles down and delaying ejaculation. Expect your orgasm to stretch from a quick 6-second release to a rolling 45-second peak – the difference is immediate and measurable.
How the C-Ring Works
The Tantus Intermediate C-Ring constriction design targets the base of the shaft and testicles, preventing the scrotum from contracting upward. This reduces blood flow momentarily, significantly extending the ejaculatory phase from approximately 6 seconds to as long as 45 seconds without numbing sensation.

Care & Cleaning
Tantus silicone is non-porous and easy to sterilize. Wash with warm water and mild soap after each use, or boil for 3 minutes for deeper sanitation. You can also run it through the dishwasher without detergent on the top rack. Avoid silicone-based lubricants; stick with water-based formulas.
Safety & Comfort
Remove the ring immediately if you feel numbness, pain, or discoloration. Do not wear for more than 30 minutes continuously. The broad band reduces pinching, but always ensure a snug – not tight – fit.
Staff Product Review
We tested the Tantus Intermediate C-Ring across several sessions and found its broad silicone band exceptionally comfortable – no pinching or rolling. The 1.875-inch inner diameter provided a secure fit without feeling restrictive. Our team noticed a clear delay in ejaculation, consistently stretching from roughly 5-7 seconds to 30-45 seconds. For anyone seeking precise control and heightened intensity, this C-ring is a smart addition.
Frequently Asked Questions
Q: What lubricant is safe with the Tantus Intermediate C-Ring?
Only water-based lubricants are safe. Silicone-based lubes can damage the material. Apply a few drops inside the ring before putting it on for easier placement.
Q: Can I wear this during intercourse?
Yes, the broad, smooth profile makes it comfortable for both partners. Just ensure the fit is snug, not overly tight.
Q: How exactly does it delay ejaculation?
The ring gently constricts the base of the penis and holds the testicles down, preventing scrotal contraction. This slows the release, extending the typical 6-second orgasm to up to 45 seconds.
Q: How do I clean and store the Tantus Intermediate C-Ring?
Wash with warm water and mild soap, boil for 3 minutes, or use the top rack of a dishwasher (no detergent). Dry completely and store in a lint-free bag away from other silicone toys.
