Edward Z. ★★★★★

The 75 durometer feels just right—pliable enough to seat perfectly but firm enough to hold a seal under pressure. I used these on a high-temp manifold, and they've held up to 350°F without any issues so far. Exactly what I needed for this application.

Victoria L. ★★★★★

The brown color makes them easy to spot during assembly, and the 75 durometer feels just right for my hydraulic lines. I've had them on for two weeks with zero leaks, even at temps pushing 350°F.

Thomas ★★★★★

I needed a high-temp seal for my compressor's hot oil return line, and these Viton FKM rings handle the -15°F to +400°F range perfectly. The 0.139" cross-section gave just the right snug fit, and the package of ten was exactly what I needed for the job.
