Customer Reviews (4.6 / 5 · 5 reviews)

James ★★★★★

Ordered these for a hydraulic cylinder rebuild and the 70 durometer feels just right—not too stiff, not too soft. The batch was consistent, no flash or deformities on any of the 1000 rings. Definitely saving these for future seal replacements.

Penelope ★★★★★

Finally found a bulk pack that actually matches the AS568 spec precisely—these 113s fit my pneumatic fittings perfectly. The 70 durometer is firm enough for a good seal but still flexible to install easily.

Joseph J. ★★★★★

Needed to replace a worn hydraulic seal and these o-rings fit perfectly and the 70-durometer hardness feels right for the pressure. The 0.549" ID matched the groove exactly, and the whole bag of 1,000 came neatly packed.
