David O. ★★★★★

Installed these on a hot water recirculation pump that was leaking; the -65°F to +300°F range gave me confidence they'd hold up. The 70 durometer feels pliable yet firm, and the whole pack of 130 should last me years of repairs. No leaks so far after a month of use.

Grace I. ★★★★★

I’ve been using these EPDM o-rings on a hydraulic fitting that sees a lot of heat, and the -65°F to +300°F range gives me real peace of mind. The 1.421" ID is a snug fit, and the rubber feels durable enough for long-term service.

Lucy ★★★★★

The 1.421" inner diameter fits my pump housing perfectly, and the EPDM's 300°F rating gives me peace of mind for the hot oil it's sealing. All 130 rings arrived uniform with no flash or defects, so I've got spares for years.
