Mia A. ★★★★★

I needed a replacement for a hydraulic seal that kept leaking, and these 156-size HNBR o-rings fit perfectly. The -40°F to +300°F temperature range gives me confidence they'll hold up in both my cold garage and by the engine.

Joshua ★★★★★

The 80 durometer hardness makes these feel more substantial than the soft rubber gaskets I've swapped out, and they seated perfectly in the groove without rolling. I've got a spare set ready for the next rebuild since this pack of 25 covers a lot of ground.

Michael ★★★★★

The 80 durometer rating feels just right for the moderate pressure I'm putting these through, and they haven't shown any swelling after a week in hot oil. Perfect for chemical resistance, too.
