George ★★★★★

These Viton o-rings handled the hot transmission fluid in my old tractor perfectly, no swelling or hardening after a week at 180°F. The 75 durometer makes them firm enough to seat well without being a struggle to install.

Ruby ★★★★★

Had a tough seal to make on a steam line that other o-rings couldn't handle, but these Viton FKM ones have held up perfectly at high temps. The 2.609" inner diameter was spot on for the groove, and they arrived quickly.

Richard ★★★★☆

The 75 durometer feels just right for my hydraulic fitting—not too stiff, yet firm enough to hold pressure. I wish the package had a few more for the price, but they seated perfectly on the first try.
