Hazel G. ★★★★★

The 70 durometer hardness feels just right for a solid seal on my hydraulic fittings without being a pain to stretch into place. The 7.225" ID sat snugly in the groove and handled the hot oil cycling up to 200°F without any leaks.

Timothy ★★★★★

The dash 360 size was a perfect match for my hydraulic fitting, and the 70 durometer hardness feels sturdy without being brittle. These should last a while given the -40 to 250 degree range they're rated for.

Benjamin ★★★★★

The 0.21" cross-section is just right for the pump seal I rebuilt—fit snugly without forcing it. These Buna-N rings handled the hot oil without swelling, which was my main worry. Definitely ordering another pack for spares.
