Customer Reviews (4.8 / 5 · 5 reviews)

Olivia ★★★★★

The 90 durometer feels perfect for my application—these should hold up well under constant pressure. I also appreciate the wide temperature range, as my equipment sees everything from freezing startups to hot oil circulation.

Emily ★★★★★

I bought these for a high-temp hydraulic application, and the HNBR material held up perfectly under continuous 250°F exposure. The 0.139" cross-section seals tightly without any deformation.

Adam ★★★★★

The 90 durometer definitely gives these a firm, reliable seal in my pneumatic fittings, and the -40°F low-temp rating was exactly what I needed for my outdoor equipment. I've installed a dozen so far with no issues.
