Customer Reviews (4.6 / 5 · 5 reviews)

Richard L. ★★★★★

I needed a replacement for a worn seal on a hydraulic fitting, and these AS568-455 o-rings fit perfectly without any fuss. The 70 durometer rubber feels firm but not brittle, and they've held up well to the 100°F machine oil temps I've been running.

Aurora ★★★★★

The 70 durometer rating was spot on for my pneumatic cylinder rebuild — they seated perfectly without leaking. Fourteen per pack is enough for a couple of jobs, and the -40°F rating gives me confidence for winter use.

George W. ★★★★★

I needed these for a hydraulic repair on my tractor, and the -40°F rating gives me peace of mind for winter use. They seated perfectly in the groove without any deformation.
