Customer Reviews (4.8 / 5 · 5 reviews)

Olivia K. ★★★★★

These are a perfect fit for my hydraulic cylinder rebuild, and the 90 durometer feels noticeably firmer than the standard ones I've used before. At 400 in a pack, I have plenty of spares for future repairs.

William D. ★★★★★

I needed a bulk supply of 90 durometer o-rings for a hydraulic repair job, and these AS568-136s fit perfectly with a snug, reliable seal. The 400-count package is great value for any shop.

Hazel I. ★★★★★

These 90 durometer o-rings are noticeably stiffer than standard ones, which made them perfect for a high-pressure pneumatic assembly I was rebuilding. The 400-count pack will last me years, and at this price per ring it's a steal.
