Customer Reviews (4.8 / 5 · 5 reviews)

Steven ★★★★★

Got these for a pool pump rebuild and the -40°F rating gave me confidence they'd seal in the dead of winter. The 0.139" cross-section fit perfectly into the grooves without any trimming.

Emma ★★★★★

The 70 durometer hardness feels just right for sealing my pneumatic fittings without being too stiff. These o-rings fit perfectly in the grooves and the temperature range is exactly what I need for my application.

Madison ★★★★★

I needed a reliable batch for a hydraulic repair job, and these 0.139" cross-section rings sealed perfectly on the first try with no leaks. The 70 durometer feels just right, not too stiff or too soft.
