Avery B. ★★★★★

These o-rings fit the hydraulic cylinder on my log splitter perfectly once I measured the groove. The 50 durometer rubber is noticeably softer than the standard 70, which should let them conform better to the old pitted surfaces. They slid right into place and the leak stopped immediately.

Joseph H. ★★★★★

I was looking for a replacement seal that could handle some heat cycling in a pneumatic manifold, and these 50 durometer o-rings fit the bill perfectly. The bag of 80 is more than enough for future repairs, and the -40°F rating gives me peace of mind.

Sophia ★★★★★

I needed a soft seal for a low-pressure air system, and these 50 durometer rings fit perfectly without distorting. The 2.984" inner diameter seated snugly, and they reached my shop in just three days.
