Daniel ★★★★★

These will handle Texas summers without a second thought, and the 90 durometer means they don't squish out of the groove under pressure. I bought the 600-pack so I'm set for years of rebuilds, and for that price it's a steal.

Riley ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal—these don’t squish out of shape like softer rings I’ve tried. The -40°F rating gives me confidence for my outdoor equipment through winter.

Amelia ★★★★★

These have been holding up perfectly in my hydraulic press application, handling the heat without any softening. I'm glad I went with the 90 durometer for this job.
