Customer Reviews (4.4 / 5 · 5 reviews)

Chloe C. ★★★★★

The 90 durometer rating on these rings is noticeably stiffer than the standard ones I've used before, which makes them feel much more secure in the groove. At 500 per package, I've got plenty of spares for future rebuilds without worrying about running out.

Stella ★★★★★

The 90-durometer nitrile feels perfect for the high-temp applications I needed — these should hold up well under the hood. Fit the shaft exactly with the 1.486" ID. A solid box of 500 at this price is hard to beat.

Madison ★★★★☆

I needed a tougher seal for a hydraulic cylinder and these 90 durometer o-rings fit the bill perfectly. The only thing is 500 in a pack is way more than I'll ever use, but the price for the quantity is hard to beat. They fit the groove snug with no slack.
