Matthew R. ★★★★★

These worked perfectly for a hydraulic repair on an old tractor, the 70 durometer feels firm enough to hold pressure without being too hard to seat. Almost fits like a glove on the groove, and the -65°F rating means they won't get brittle in our cold winter.

John Q. ★★★★★

Installed these in a few brass fittings around my pool filter system and they sealed tight on the first try. The -65°F to +300°F range gives me peace of mind for year-round outdoor use.

Isabella ★★★★★

These fit perfectly in the standard hydraulic fitting I needed to rebuild, and the EPDM material handles the heat exposure without any issue. The 550-count pack is way more than I'll use, but the price was right for the bulk.
