Customer Reviews (4.6 / 5 · 5 reviews)

Thomas ★★★★★

I needed some reliable o-rings for a hydraulic application and these fit like a dream. The 50 durometer is noticeably softer than the standard 70, which made installation much easier. For a bulk pack of 200, the price feels more than fair.

Chloe ★★★★★

The inner diameter is a perfect fit on our hydraulic cylinder cap, and the 50 durometer seals far better than the harder rings we tried before. These handled the -40°F startup test without cracking.

Ella N. ★★★★★

I needed a softer seal for a low-pressure application and these 50 durometer o-rings fit the bill perfectly. The 2.236" inner diameter was exactly right for my setup, and they seat nicely without forcing.
