Christopher ★★★★★

These fit perfectly on my hydraulic fittings and the 70 durometer feels stiff enough to hold pressure without being a struggle to install. Nice to have a full pack of 250 so I can knock out all my replacements in one go.

Olivia ★★★★★

Just rebuilt a pneumatic manifold on an industrial press, and these AS568-325 rings seated perfectly in every groove. The 70 durometer material feels exactly right for static seals, and the 0.21" cross-section matched my old ones spot-on.

Timothy ★★★★★

I needed a batch of these for a hydraulic repair job on an old press, they fit the groove perfectly and the -40°F rating gave me peace of mind since the shop can get pretty cold in winter.
