Isabella ★★★★★

The -40°F rating is exactly what I needed for my outdoor hydraulic equipment that sits through winter, and these 50-durometer rings slipped into the grooves without any struggle. They seat perfectly and haven't leaked a drop since installation.

George ★★★★★

The 50-count pack is great value for the price, and these 50-durometer seals fit my application perfectly. I appreciate that they're rated for up to 250°F since my setup runs warm.

Julian ★★★★★

Exactly what I needed for a hydraulic cylinder rebuild—the 50 durometer softness sealed perfectly without being too stiff. They slid right into the grooves, and the -40°F rating gives me peace of mind for winter use.
