Sebastian ★★★★★

Replaced both the valve cover and the fuel rail gaskets on my old truck and these seated perfectly, no leaks after a week of daily driving. The 50 durometer gives them just enough flex to stay put in the groove while still sealing tight under the clamps.

Amelia M. ★★★★★

The 50-durometer hardness is just right for my pneumatic fittings—soft enough to seal without being a pain to install. These came packaged securely and the 2.85" ID fits my application exactly.

James F. ★★★★★

The 0.21" cross-section is a perfect match for a water housing seal I replaced. At 50 durometer, they sit just soft enough to squish into place without rolling.
