Customer Reviews (4.8 / 5 · 5 reviews)

Joseph ★★★★★

The service temp range down to -40F is exactly what I needed for my outdoor equipment, and these 80 durometer o-rings feel noticeably more durable than the standard ones I used before. They sealed perfectly on the first try.

Scarlett ★★★★★

The 80 durometer hardness made these o-rings feel sturdy right out of the package, and they fit perfectly into our pneumatic valve housing. The chemical resistance seems solid so far with no swelling after a week of use.

Julian ★★★★★

The temperature range was the deciding factor for me, and these HNBR o-rings handle the -40°F to +300°F swing my application needs without any issues. The 80 durometer hardness gives a solid, reliable seal that hasn't budged since install.
