Product Details

The seal has a low coefficient of friction and the friction between the contact faces is minimal among all seal types. Moreover, the contact pressure between the mating surfaces is low. It can work without lubrication and is very wear resistant. And it has a long service life.

The virgin Teflon spring energized seal produced by XLONG SEALS is perfect for being applied to extremely high-speed, very low-speed equipment with micro piston strokes and other special operating conditions. It can be used with rotary seals and maintains good sealing performance in violent shake and vibration motion environments. At the same time, our seals are extremely adaptable to a wide range of working media. It is resistant to a wide range of chemicals. Therefore, it works well with liquids such as oils and water with high and low temperature.
