Description
Rod Type Spring Energized Seals is a kind of single-acting sealing element optimized for low to medium pressure fluid sealing. The unique characteristic of the slant coil spring means the spring force is relatively constant over a wide deformation range, giving controllable and constant friction. The material gives almost universal compatibility with fluids or chemicals and its wide temperature range allows it to be used under extreme conditions. The Rod Type Spring Energized Seals can offer low friction with no stick-slip, minimal break-out force, and high wear resistance. Resistant to most liquids and chemicals, it has an unlimited shelf life.
