Customer Reviews (4.4 / 5 · 5 reviews)

Michael ★★★★★

The 50-durometer material is noticeably softer than standard o-rings, which made fitting them into a tight groove much easier. I used these on a coolant line that sees temperatures around 200°F, and they’ve held up perfectly so far.

Ella ★★★★★

I needed o-rings for a hydraulic repair and the 0.984" ID fit perfectly, no binding or leaks so far. The rubber feels firm but not brittle, and they seat well at room temperature before any heat cycling.

Charlotte ★★★★★

These 50-durometer rings are noticeably softer than the standard 70-durometer ones I've used before, making them much easier to seat in tight grooves. The 0.984" inner diameter seals perfectly on my irrigation fittings, and the 130-piece pack is a solid value.
