Daniel ★★★★★

The 50 durometer is noticeably softer than standard ones, which made for a perfect seal on my low-pressure air line without over-tightening. These fit the groove snug and arrived well-packaged, with no oil or damage. I’ve already ordered another pack for future repairs.

Alexander R. ★★★★★

Needed these for a hydraulic fitting on an old press, and the 50 durometer made installation much easier than the harder ones I've tried. The -40° to 250° range gives me confidence they'll hold up in my unheated shop all year.

Steven P. ★★★★★

The 50 durometer softness on these o-rings made for a perfect seal on my hydraulic fitting without needing a ton of force to compress. They fit the groove exactly as the AS568-224 spec promised.
