Customer Reviews (4.8 / 5 · 5 reviews)

Emma B. ★★★★★

The 70 durometer hardness feels just right for the high-pressure seal I needed, and the -40°F to 250°F range gives me peace of mind for winter use. These replaced some worn-out rings and stopped the leak on the first try.

Sofia I. ★★★★★

These fit my machine’s hydraulic system perfectly—the 70 durometer feels solid without being too stiff. Good value for a 20-pack of this dash size.

Lucy ★★★★★

Was worried about the temperature range for an outdoor application, but these have held up fine in the summer heat so far. The 70 durometer feels just right for the seal I needed.
