Charlotte D. ★★★★★

These o-rings seated perfectly in my pump rebuild kit, and the 70-per-pack quantity means I have spares for future projects. The -40°F rating gives me confidence they'll hold up in my unheated workshop during winter.

Brian G. ★★★★★

I needed a reliable seal for a hydraulic cylinder rebuild, and these o-rings fit perfectly with their 3.234" ID and 50 durometer. The compound feels consistent and firm against the groove, exactly what I was hoping for.

Nicholas N. ★★★★★

The 70-pack gave me plenty of spares for my pneumatic fittings, and the 50-durometer material seals much better than the harder ones I used before. These fit my application perfectly.
