Charlotte I. ★★★★★

I was worried about finding the right o-ring for a high-temp application, but these Buna-N ones handle up to 250°F without any issues. The 70 durometer feels just right—not too stiff, not too soft during installation.

Joshua O. ★★★★★

The dash 456 fit perfectly on my quick-connect fittings, and the -40°F to +250°F range gives me peace of mind for winter projects. Ten in the pack is just right for spares.

Henry R. ★★★★★

These o-rings fit perfectly into my hydraulic assembly, and the 70 durometer rubber feels exactly like what I needed for a tight seal. I'm glad I went with the -456 size based on my groove measurements.
