Michael B. ★★★★★

Used these on a hydraulic cylinder rebuild and they seated perfectly with no leaks. The 90 durometer holds up well under high pressure, and the temperature range covers everything I need in the shop.

Ellie ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal—it sits snug in the groove without any squish. Also, the -40°F to +300°F range covers my outdoor equipment perfectly through winter.

Ava ★★★★★

Needed o-rings that could handle higher temps near a steam valve, and these HNBR ones are holding up perfectly at 300°F. The 90 durometer feels firm but seals well, and the 2.799" ID was an exact fit.
