Hannah D. ★★★★★

Installed these on a 1970s air compressor piston seal and they seated snug without any trimming. The 70 durometer feels just right for this application, and the -40°F rating gives me confidence for winter use.

Jacob ★★★★★

These fit perfectly on the old hydraulic cylinder I rebuilt last week. The buna-n material feels appropriately firm and they seat well without twisting, and I've got plenty left over for future projects.

Scarlett ★★★★★

I was worried about finding the right o-rings for a hydraulic repair, but the 70 durometer hardness feels just right for the seal I needed. The whole pack arrived neatly organized, and they fit perfectly on the first try.
