Miles ★★★★★

These are the exact size I needed for a hydraulic repair, and the 200-count pack means I won't be running out for a while. The -40°F to +250°F rating gives me peace of mind for the temperature swings in my shop.

William G. ★★★★★

The 70 durometer hardness feels just right for my hydraulic fitting, and the pack of 200 should last me through several projects. They seated cleanly into the grooves without any deformation, so I’m confident in the seal.

Emma P. ★★★★★

I needed a bunch of these for a pneumatic cylinder rebuild, and the 70 durometer feels just right—not too hard, not too soft. They seated perfectly with no leaks on the first test.
