The size is imprinted on each ring. If you are unsure which size is right for your anatomy, start with RND03 (moderate tension) and move toward RNDX for firmer compression if needed. For guidance call us: 866-218-0902.
Who Needs the RNDX?
The RNDX is the appropriate ring when:
- You have tried larger sizes and erection maintenance is still insufficient
- Your erection subsides quickly (under 5 minutes) even with a tension ring in place — indicating significant venous leak requiring maximum compression
- Your urologist or physician has specifically recommended the firmest available ring
- You are replacing an existing RNDX ring that has worn out
FAQs
How do I know if RNDX is the right size for me?
If you have already tried RND01 or RND02 and are losing erection before intercourse is complete, the RNDX provides the firmest compression available in the Ultimate II range. If you are new to tension rings, start with RND03 (moderate) and work toward the RNDX only if softer sizes prove insufficient. Correct ring tension should maintain a firm erection comfortably without causing numbness, pain, or difficulty with ejaculation.
Can I use the RNDX with systems other than Pos-T-Vac?
Yes — Pos-T-Vac Ultimate II rings are widely used with other VED brands and as standalone erection rings without a pump. The ring diameter and material are compatible with most standard cylinder openings and can be applied directly to the penis base without a VED for men managing venous leak with natural erections.
What is HCPCS E1399?
E1399 is the HCPCS miscellaneous durable medical equipment code. Submit the code with a sales receipt to your insurer for potential partial reimbursement — particularly relevant for post-prostatectomy rehabilitation use. Coverage varies significantly by plan.
How long does one ring last?
Approximately 20–30 uses with proper care: water-based lubricant only (oil degrades silicone), rinse with mild soap and warm water after each use, air dry fully, store away from heat and direct sunlight.
