Ruby ★★★★★

I needed a seal that could handle extreme heat cycling, and these PTFE o-rings with their 0.139" cross-section fit perfectly in my steam line flange. They've held up through multiple 400°F runs without any visible wear, which is exactly what I was hoping for.

George S. ★★★★★

The 22 durometer rating on these rings is impressively soft, so they seated into the groove without any wrestling match. I grabbed these for a high-temp line and the -350°F to +500°F range gives me real peace of mind. The count of 30 per pack means I've got spares for the next job, which is exactly

Miles ★★★★★
