Customer Reviews (4.4 / 5 · 5 reviews)

Emily ★★★★★

The 1.296" inner diameter fit perfectly on my hydraulic fitting, and the -40°F low-temp rating gives me confidence for outdoor use this winter.

Olivia K. ★★★★★

The 50-durometer hardness is perfect for my air line fittings, and the -40°F rating gives me confidence they'll hold up in my unheated workshop. Fit the groove snugly on the first try.

Owen K. ★★★★★

The 50 durometer on these is noticeably softer than the standard 70, which made fitting them into a tight groove much easier than I expected. For a hundred and twenty pack, the price is unbeatable for a project needing a bunch of seals.
