Customer Reviews (4.8 / 5 · 5 reviews)

Grace Y. ★★★★★

The 70 durometer feels just right for my application—firm enough to hold a seal but not brittle when I stretched one over the fitting. These have handled some hot oil exposure around 200°F without any visible swelling or hardening so far.

Adam F. ★★★★★

Pulled these out for a hydraulic cylinder rebuild and the 70 durometer is stiff enough to hold pressure without being impossible to seat. Fit the dash 473 groove perfectly on the first try.

Ruby W. ★★★★★

Finally found AS568-473 o-rings that actually fit my hydraulic valve rebuild without being too stiff. The 70 durometer rating gave just the right amount of squeeze for a solid seal.
