Joseph W. ★★★★★

Had to replace the old o-rings on a hydraulic cylinder and these are a perfect drop-in fit. The 200-count package is great for having spares on hand.

Amelia ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal, and the 200-count box means I’ve got spares for the next few rebuilds. Measured one with calipers to double-check the ID and it’s spot on at 1.6 inches. These feel dense and cut-resistant, no issues seating them in the groo

Isabella M. ★★★★★

I needed o-rings that could handle both hot and cold without getting brittle, and these Buna-N ones have been holding up perfectly in my outdoor hydraulic system. The 90 durometer gives them a nice firm feel when seated.
