Hannah W. ★★★★★

Installed these on a hot oil line that regularly runs past 300°F and they haven't softened or deformed after a month of cycling. The 75 durometer hardness feels just right under the wrench, and the brown color makes them easy to spot during inspection.

Charlotte I. ★★★★★

Put these on my homebrew keg's pressure relief valve and the Viton material held up perfectly during a 30-minute boil cycle. The brown color makes them easy to spot against the metal, and the 75 durometer feels just right for a snug seal.

Chloe ★★★★★

Fit these Viton o-rings perfectly on my old hydraulic pump, and the 75-durometer rubber feels much more durable than the standard Buna ones I used before. They sealed up the leak on the first try, even with the fluid running hot.
