Benjamin N. ★★★★★

Pulled one out to test fit on a hydraulic fitting and it seated perfectly with the 0.21" cross-section giving a nice snug seal. These Viton rings handle the heat from my compressor no problem.

George B. ★★★★★

The 90 durometer hardness gives these a nice, firm feel that makes them easy to install without rolling or twisting. I've used a few of them in a hot fluid line sitting around 300°F and they've held up perfectly so far. For the price, having 70 in the bag means I've got plenty of spares for future p

Hazel ★★★★★

I was worried about getting a tight seal on a high-temp chemical line, but these FKM o-rings fit perfectly and have held up well even at 200°F. The pack of seventy is way more than I needed for one job, but the price per ring is hard to beat.
