Customer Reviews (4.8 / 5 · 5 reviews)

Grace K. ★★★★★

I used these in a high-temp engine gasket repair and the 300°F rating gave me confidence they’d hold up. The cross-section thickness feels just right for a snug fit without being too stiff to install.

Evelyn ★★★★★

The 80 durometer hardness is exactly what I needed for a high-pressure fitting, and they slid on without any tearing. HNBR handles the heat range well, so I'm confident they'll last in my hot oil application.

Matthew A. ★★★★★

I've been running these o-rings in a hydraulic actuator that sees 275°F cycles, and the 80 durometer holds up better than the standard Buna-Ns I used before. No signs of hardening or cracking after a week of constant heat.
