Mia ★★★★★

I needed a solid seal for a hydraulic fitting that sees temps around 250°F, and these o-rings fit the bill. The 70 durometer feels durable and the -65°F to +300°F range gives me confidence. Exactly what I needed for the job.

Hazel ★★★★★

I’ve been replacing old seals in a hot water circulation line, and these EPDM o-rings handled the 200°F temps without any softening or leaks. The 70 durometer feels just right—firm enough to hold pressure, but still flexible to seat easily.

Harper ★★★★★

These fit snugly and sealed the water line on my RV without a drop. I replaced all the old cracked ones at once since the pack of 300 is a solid deal, and the 70 durometer feels plenty firm for the job.
