MaxPR ring fit: snug, adjustable, made to hold
Last updated: November 2026 · Published by FirmTech
The MaxPR ring fit is FirmTech's snuggest: slimmer and tighter than its Performance Ring, adjustable, and sized for up to 5.5 inches erect girth.
The FirmTech MaxPR loops around the base of the penis and behind the testicles, spreading pressure evenly, while an adjustable hook-and-latch lets you set the tension. FirmTech rates it 5 of 5 for tightness, lists a safe wear time of up to 90 minutes, and sells it for $60.

How should the MaxPR fit?
The MaxPR should feel snug and firm at the base without pinching or pain.It is designed to hold blood in place with firmer pressure than FirmTech's original ring, so a noticeably tighter feel is expected.
Because you control the tension with the hook-and-latch, you can start a little looser and tighten until it feels secure. If you feel pain, numbness or coldness, loosen it or take it off. FirmTech lists 90 minutes as the maximum wear time for the MaxPR, shorter than its other rings because it is the tightest.
What is the MaxPR?
Definition
The MaxPR is FirmTech's tightest erection ring: the same doctor-designed peno-scrotal shape as the Performance Ring, made slimmer and snugger for extra pressure. FirmTech describes its benefits as fuller, firmer, longer-lasting erections, heightened sensation and a more intense finish. It is made of medical-grade elastomer that is phthalate-free and latex-free, it is water resistant, and it has nothing to charge or pair. It does not track any data; for tracking, FirmTech makes the TechRing. The MaxPR costs $60, is HSA/FSA eligible, ships in a plain unbranded box, and carries a 3-month warranty plus FirmTech's 30-day money-back guarantee. FirmTech rates it 5 of 5 for both tightness and pleasure, the highest scores among its three rings.

How to put on the MaxPR
Open
Unhook the latch and open the loops so the ring lies flat.Place
Loop it around the base of the penis and the testicles. One loop sits behind the testicles and the other around the base.Adjust
Fasten the latch at the tension that feels right: snug and secure, never painful. Readjust any time.
FirmTech says its rings are designed to go on when you are soft, so you can put the MaxPR on ahead of time. Use water- or silicone-based lubricant only; FirmTech says natural oils such as coconut or CBD oil should not be used with its rings.
MaxPR vs Performance Ring fit
| Fit detail | MaxPR | Performance Ring |
|---|---|---|
| Shape | Same doctor-designed shape, slimmer | Original doctor-designed shape |
| Tightness | 5 of 5, Tightest | 3 of 5, Comfort |
| Pleasure | 5 of 5, Most intense | 3 of 5, Enhanced |
| Safe wear time | Up to 90 minutes | Up to 12 hours |
| Adjustment | Hook-and-latch | Hook-and-latch |
| Erect girth range | Up to 5.5 in (14 cm) | Up to 5.5 in (14 cm) |
| Price | $60 | $60 |
Both rings cost the same, so the choice comes down to feel. If you want the strongest hold for shorter sessions, the MaxPR fits better. If you want to wear a ring for hours, the Performance Ring is the better match. Many men keep both.
Signs your MaxPR fit is right
FirmTech founder Elliot Justin, M.D., explained that the MaxPR came from customers who wanted a snugger fit that does not pinch like harder silicone rings and can be worn for over 20 minutes without compromising blood flow (FirmTech ring comparison article). That gives a useful test for your own fit:
- It feels firm and secure at the base, not loose.
- It does not pinch, cut in, or cause sharp pain.
- Skin color and sensation stay normal while you wear it.
- You can stay within the 90-minute wear time comfortably.
If your erect girth is over 5.5 inches, or the fit is not right, contact FirmTech or use the 30-day money-back guarantee. Sizing details are on the ED ring size chart.

Common questions
How should the MaxPR ring fit?
The MaxPR should feel snug and firm at the base without pinching. It loops around the base of the penis and behind the testicles, and the hook-and-latch lets you set the tension. FirmTech calls it its snuggest hold, slimmer and tighter than the Performance Ring. If it hurts, loosen it or take it off.
See this in the full FAQHow do I put on the MaxPR?
Putting on the MaxPR takes three steps. First, unhook the latch and open the loops. Second, place it so one loop goes around the base of the penis and the other around the testicles. Third, adjust the latch to the tension that feels right, snug but not painful.
See this in the full FAQHow is the MaxPR fit different from the Performance Ring?
The MaxPR is slimmer and snugger than the Performance Ring. FirmTech rates the MaxPR 5 of 5 for tightness and the Performance Ring 3 of 5. Both use the same doctor-designed peno-scrotal shape and hook-and-latch. The tradeoff is wear time: up to 90 minutes for the MaxPR versus up to 12 hours.
See this in the full FAQWhat if my erect girth is over 5.5 inches?
FirmTech lists 5.5 inches (14 cm) erect girth as the fit limit for all three of its rings, so a larger girth falls outside that range. Contact FirmTech customer service through its contact page before ordering to ask about your fit. Purchases are also covered by FirmTech's 30-day money-back guarantee.
See this in the full FAQHow long can I wear the MaxPR?
FirmTech lists the MaxPR's safe wear time as up to 90 minutes at a time. That is shorter than the Performance Ring and TechRing, which are listed at up to 12 hours, because the MaxPR is FirmTech's tightest ring. Take it off if you feel pain or numbness sooner.
See this in the full FAQHow is the MaxPR different from hard silicone rings?
FirmTech founder Elliot Justin, M.D., said customers wanted a snugger fit that does not pinch like harder silicone rings and can be worn for over 20 minutes without compromising blood flow. The MaxPR uses soft medical-grade elastomer and an adjustable hook-and-latch rather than a fixed, rigid loop.
See this in the full FAQWhat lube can I use with the MaxPR?
Use water-based or silicone-based lubricants only with the MaxPR. FirmTech says not to use natural oils such as coconut oil or CBD oil with any of its rings. FirmTech sells Sliquid Naturals Silver, a silicone lubricant, as an accessory starting at $18.
