Sophia I. ★★★★★

These o-rings fit perfectly into a hot oil pump rebuild I was doing, and the 75 durometer feels much more durable than the cheaper nitrile ones I've tried before.

Brian ★★★★★

Ran a leak test on a high-temp valve at 350°F and these FKM o-rings held perfectly, no deformation or cracking after several cycles. The 75 durometer feels just right for a snug seal without being too stiff.

Hannah ★★★★★

The heat resistance is the whole reason I bought these, and they've held up flawlessly at 350°F in my compressor setup. The 75 durometer feels stiff enough to keep a solid seal but not brittle when I stretched them into the groove. Exactly the right size for the dash 207 spec I needed.
