Matthew ★★★★★

I needed a few of these for a compressor rebuild, and the -40°F to +250°F rating gives me confidence they'll hold up in the garage. The 70 durometer feels slightly firmer than the old ones, which seems to seal better.

Andrew ★★★★★

Used a couple of these to replace old o-rings in a hydraulic fitting and the 70 durometer material sealed perfectly with no leaks. They’re holding up well under the 250°F max temp during my daily runs.

Sofia ★★★★★

Installed a few of these to fix a leaky hydraulic line on my log splitter, and they sealed perfectly under pressure. The 70 durometer feels sturdy without being too stiff, and they handled the -40°F rating well during a cold start.
