Violet T. ★★★★★

The high-temp rating is exactly what I needed for a steam valve rebuild—these Viton rings handle 400°F without issue. They seated perfectly on the first try and the 90 durometer feels solid. Exactly the right size for my application.

Adam ★★★★★

Used one of these to fix a leaky hydraulic fitting on my log splitter, and it sealed perfectly from the first pressurization. The 90 durometer feels noticeably stiffer than the standard Buna-N ones I usually buy.

Emma M. ★★★★★

Finally got these to replace a worn-out seal on a high-temp line, and the 90 durometer feels noticeably stiffer than the stock rubber ones. They slipped on cleanly and held up fine so far at around 350°F. The pack of 16 is nice to have spares on hand for future jobs.
