After I put it to the test, I must say that these gaskets are game-changing. They perfectly sealed the leaks and I never had to worry about dripping or leaking again. They work great in both hydraulics and PNEUMATICS applications .The gaskets are made of high-quality silicone, which makes them durable and long-lasting. One downside is that they are only available in limited sizes, but the ones they offer are pretty common. Overall, I am happy with my purchase, and i would recommend them to anyonSee full review
