Customer Reviews (5.0 / 5 · 5 reviews)

Charlotte ★★★★★

Installed these on a high-temp hydraulic fitting that regularly sees 300°F and they seated perfectly without any leaks. The 75 durometer feels just right for this application.

Benjamin U. ★★★★★

Slid them onto the valve stems and they seated perfectly without any wrestling, which is rare for o-rings this size. The 75 durometer is firm enough for a tight seal, and knowing they handle up to 400°F gives me peace of mind for the hot oil side of my setup.

Grace R. ★★★★★

The 75 durometer hardness feels just right for my application—firm enough to hold a seal but still pliable when I wrestle them into the groove. The brown color makes them easy to spot during assembly, and with the 400°F rating I'm confident they'll hold up in the hot oil service I run.
