Customer Reviews (4.4 / 5 · 5 reviews)

William ★★★★★

Needed a replacement for a hydraulic seal that kept failing at high temps, installed this HNBR ring and it's been running smooth even with oil temps around 250°F. The 0.139" cross-section is noticeably more robust than the old o-ring.

Timothy ★★★★★

The 4.734" inner diameter fits my pump housing perfectly, and the 80 durometer gives a tight seal without being impossible to install. I've used these in hydraulic fluid up to about 250°F with no issues at all.

Elizabeth ★★★★★

Installed a set on a high-temp pneumatic valve that kept failing with standard Buna-N rings. The HNBR material handles the heat much better and has held up through several hot cycles now without any leaks.
