Michael Q. ★★★★★

For a replacement gasket on an old hydraulic cylinder, the 2.736" inner diameter fit perfectly, and the -40°F rating gives me peace of mind in my unheated shop.

Nicholas ★★★★★

The 50 durometer softness is exactly what I needed for a low-pressure seal; they seat easily without distorting. A full bag of 125 means I've got plenty of spares for future projects, and the -40°F rating gives me confidence they'll hold up in my unheated garage.

Stella ★★★★★

I bought these for a hydraulic cylinder rebuild and they seated perfectly on the first try. Even with the colder weather we've been having, they sealed without any issues. The 125-count pack will last me through several projects.
