Customer Reviews (4.6 / 5 · 5 reviews)

Edward U. ★★★★★

I was impressed with the tight fit of these AS568-411 o-rings on my hydraulic fittings—they held pressure perfectly. The 70 durometer feels sturdy but not overly stiff, which made installation easier than I expected.

Samuel ★★★★★

I replaced the old seals on my pneumatic actuator with these, and the 70 durometer feels just right for the application. They slid into the grooves perfectly and held pressure without any leaks so far.

Timothy ★★★★★

I bought these to rebuild a hydraulic cylinder on a small tractor attachment, and the AS568-411 size was exactly what the manual called for. The 70 durometer feels firm enough to hold pressure, and they slid right into the groove without any splitting.
