Owen D. ★★★★★

Needed a reliable seal for a high-temp hydraulic line and these HNBR rings handled the 300°F service limit without a hiccup. The 0.21" cross-section sits snug in the groove, and the 80 durometer feels firm but not brittle. Twelve in the pack means I've got spares for the next three repairs.

Brian T. ★★★★★

The temperature range on these is exactly what I needed for a hot oil application. They seated perfectly in the groove and haven't shown any signs of swelling.

Joseph I. ★★★★★

Used these to replace a worn seal on a hydraulic cylinder and they seated perfectly, no leaks. The 80 durometer feels just right for the pressure we're running, and the temperature range covers our needs. Have a second pack already in my cart for spares.
