Zoe C. ★★★★★

I needed a specific 407 size for a hydraulic repair, and these fit perfectly right out of the bag. The 70 durometer feels just right for the application, and the 55 pack gives me plenty of spares for future jobs.

Nicholas ★★★★★

The temp range sealed my confidence—these hold up through my shop’s winter cold snaps without getting brittle. The 70 durometer feel is spot on for a snug fit, and all 55 rings came cleanly molded with no flash to trim.

Nicholas ★★★★★

Got my hydraulic press back up and running with these dash 407 o-rings. They fit the groove perfectly and the -40° to +250° range gives me confidence for both winter garage work and hot oil.
