Sophia ★★★★★

Needed these to seal a hydraulic fitting on a pump at work, and the 70 durometer and -65°F to +300°F range matched exactly what we needed. They seated perfectly in the groove and took the pressure without issue.

Ryan ★★★★★

I’ve been using these for a coolant manifold rebuild, and the 70 durometer EPDM is holding up great with the heat cycling. They fit snugly into the grooves with no slack, and the 26-pack gives me several spares to stash away.

Edward ★★★★☆

Was expecting a bit thicker cross-section for my high-pressure application, but the 70 durometer is holding up fine so far. These fit snugly around the 3.475" bore and seal well under normal temps.
