Michael ★★★★★

I needed a bulk pack of o-rings for a hydraulic fitting repair, and these 90-durometer Buna-N seals fit perfectly. The 0.421" ID matched my application exactly, and the rubber feels durable yet still flexible enough to seat easily. Great value for 800 pieces.

Eli O. ★★★★★

These 90-durometer o-rings are perfect for my air line fittings that see high pressure; the size spec is spot-on and the pack of 800 will last me years. Really solid seal with no leaks, exactly what I needed for a couple of tricky connectors.

Samuel J. ★★★★★

Picked up a pack of these for a hydraulic repair job, and the 90-durometer rating is noticeably stiffer than the standard stuff I've used before, which is perfect for higher-pressure seals. They fit the groove snugly and didn't deform after a few cycles. Happy with the quantity for the price.
