Stella ★★★★★

These 50 o-rings seated perfectly in my hydraulic cylinder groove; the 70 durometer feels just right for the application. They slid in without binding and sealed on the first try, no leaks whatsoever.

Ruby ★★★★★

Was pleasantly surprised how snugly these fit into the grooves—the 70 durometer feels just right. I’ve used them on a few hydraulic fittings with no leaks.

Thomas L. ★★★★★

The 0.21" cross-section fits perfectly into my hydraulic cylinder groove, and the 70 durometer feels just right—not too stiff. I've used these in a hot oil application up to 200°F without any issues so far.
