Steven U. ★★★★★

I’ve used these in some high-temp applications around 200°F and they haven’t hardened or cracked at all, which is exactly what I needed. The 90 durometer makes them firm but still easy to seat in the groove.

Ryan ★★★★★

The cross-section on these 90 durometer Buna-N rings is exactly uniform, which made seating them in the groove effortless. My pneumatic cylinders haven't leaked a bit since the swap, and they handle the 250°F operating temp without any softening.

Owen ★★★★★

Needed to replace a bunch of worn out seals on my old pneumatic cylinders, and these 90 durometer rings seat perfectly without leaking. The temperature range covers everything my shop sees.
