Adam Y. ★★★★★

The 130-pack gives me plenty of extras for future projects, and the -40°F range is perfect for my outdoor plumbing repairs. These seat nicely without distorting, a solid upgrade from the generic hardware store ones.

Olivia H. ★★★★★

The 50-durometer hardness is exactly what I needed for a light compression seal on a pneumatic fitting. These AS568-216 o-rings fit the groove perfectly and the pack of 130 should last me for years of repairs.

Jason ★★★★★

I needed a soft, precise seal for a low-pressure pneumatic application, and these 50-durometer rings seated perfectly without any binding. The 1.109" ID matched my groove exactly, and they slid into place with just the right amount of give. Really pleased with the consistent quality across all 130 p
