Thomas K. ★★★★★

The 90 durometer hardness is exactly what I wanted for a high-pressure seal, and these buna-n rings handled the -40°F test without cracking. Having 800 in one package means I won't be scrambling for spares anytime soon.

Timothy ★★★★★

I needed a big batch of 90-durometer o-rings for a high-pressure hydraulic fitting, and these Dash 115s fit perfectly. The 0.103" cross-section feels sturdy, and the 800-count is more than enough for multiple rebuilds.

Amelia ★★★★★

The 90 durometer hardness on these is perfect for my high-pressure fittings—no more squishy deformations when I torque things down. A full box of 800 means I've got spares for years, and the -40°F rating gives me confidence for winter work in the shop.
