Natalie ★★★★★

Had a leaky fitting in my hydraulic line that needed a quick fix, and these AS568-905 rings sealed it right up. The temperature range listed covers everything I use, and the 1300 count means I won't be reordering anytime soon.

Daniel L. ★★★★★

The box of 1300 arrived heavier than I expected, and the 90 durometer hardness feels reassuringly stiff for a high-pressure seal. I’ve used a few on a hydraulic fitting that sees 200°F, and they’ve held up without softening or leaking.

Jacob ★★★★★

I’ve been using these 90 durometer o-rings to rebuild a hydraulic manifold in my shop, and they seal perfectly even when the oil gets hot. The -40°F to +250°F range covers everything I need without worry.
