Customer Reviews (4.6 / 5 · 5 reviews)

Hannah ★★★★★

Used them to replace aging seals on a hydraulic press that sees 350°F daily—no leaks so far and the 75 durometer feels just right. The 40-pack was way more than I needed, but the price per ring was fair.

Abigail O. ★★★★★

These are holding up great in a steam application where my old Buna-N rings kept failing. The 75 durometer feels plenty firm, and the -15°F rating gives me confidence for the cold start cycles.

Chloe ★★★★★

I needed a seal that could handle hot engine oil, and these Viton O-rings fit the AS568-045 spec perfectly with a 3.989" inner diameter. The 75 durometer feels firm but pliable, and they sealed right up without any leaks.
