Customer Reviews (4.6 / 5 · 5 reviews)

Isabella M. ★★★★★

Using these for a high-temp hydraulic repair on a press at work, and the 90 durometer feels nicely firm but not brittle. The 800-count pack means I'll have spares for future projects.

Stella Y. ★★★★★

Installed a set of these for a pneumatic seal that sees some heat, and the -40°F to +250°F range handles it perfectly. The 90 durometer gives a firm seal without feeling brittle, and the pack of 800 means I won't need to reorder for a while.

Emily ★★★★★

The 90 durometer feel is noticeably stiffer than standard o-rings, which is exactly what I needed for a high-pressure hydraulic fitting. Fit perfectly into the groove on the first try, and the temperature range covers both my hot water and compressed air lines.
