Stella Y. ★★★★★

Finally got these to replace some worn-out o-rings on a high-temp hydraulic line, and they fit perfectly. The -15°F to +400°F range is exactly what I needed for that application.

Leo U. ★★★★★

The 90 durometer hardness gives these a solid, sturdy feel that’s made swapping out the old seals on my hydraulic fittings a quick job. I’ve had them in service for a few weeks now and the -15°F to +400°F range is reassuring, especially for the hot lines near the engine. Came in a bulk pack of 125,

Brian P. ★★★★★

The high-temp rating on these seals is exactly what I needed for a steam valve rebuild—the 90 durometer feels stiffer than standard Buna-N, which gives me confidence it'll hold under pressure. Pack of 125 should last me through several maintenance cycles on the line.
