Thomas ★★★★★

These fit perfectly on a 1/4" air line fitting I was repairing. The 70 durometer feels firm but seals nicely without needing to overtighten.

James ★★★★★

Had a stubborn leak in a pneumatic fitting that wouldn't quit - these AS568-052 o-rings sealed it right up on the first try. The 70 durometer material feels solid yet flexible enough to compress evenly.

Matthew ★★★★★

Finally gave these a try for a small hydraulic repair and the 70 durometer hardness felt spot-on for the application. The pack of 30 gives you plenty of spares for the price.
