Steven G. ★★★★★

The -909 size fits perfectly in the deep groove I needed, and the 90 durometer material feels noticeably stiffer than the cheap hardware store ones I tried before. Even after a pressure test to 150 psi, none leaked.

Steven ★★★★★

I’ve been using these 90 durometer o-rings for sealing hydraulic fittings, and they hold up perfectly under pressure without any deformation. The 1000-count package gives me plenty of spares for future projects, which is a great value for the price.

Lucy ★★★★★

The temperature range is exactly what I needed for outdoor hydraulic lines, and the 90 durometer holds up well under constant pressure. I appreciate the bulk quantity too, since I go through these fast on repairs.
