Customer Reviews (4.6 / 5 · 5 reviews)

Edward X. ★★★★★

The 70 durometer feels like the perfect balance for my air fittings—not too stiff, not too soft. I just rebuilt a pneumatic cylinder and these seals seated perfectly without any fuss. Exactly what I needed for the price.

James ★★★★★

Had a small hydraulic leak on my log splitter that needed fixing, and these AS568-170 o-rings did the trick perfectly. The 70 durometer provided just enough stiffness to seat firmly without feeling brittle. Holding up well so far in both cold starts and hot runs.

Stella N. ★★★★★

The 70 durometer is firm enough for a high-pressure water application I needed them for. The -40 to +250 range gives me confidence these will hold up in both cold and hot service. Packaged well and exactly the AS568-170 size I ordered.
