Customer Reviews (4.4 / 5 · 5 reviews)

Emily ★★★★★

The package of 500 arrived neatly boxed and each ring looks precisely molded. I needed a reliable seal for a pneumatic cylinder rebuild and these fit perfectly with no deformity.

Penelope L. ★★★★★

Installed these on a hydraulic cylinder rebuild and the 70 durometer Buna-N handled the -40°F startup temps without any cracking. The fit on the AS568-113 groove was exactly right, and having 500 in the bag means I'm set for future projects too.

Miles ★★★★★

The 70 durometer hardness is perfect for my hydraulic repair kit—these o-rings seal tight without being too stiff. The 500-count pack will last me through multiple jobs, which is exactly what I needed for my small shop.
