Product Introduction
Description
Wiper seals PT2 is consisting of one profile ring made from PTFE with a sealing edge and a wiper edge, as well as two O-rings as sealing and pre-load components. It is a double-acting, two o-ring energized, rod wiper/excluder designed to include two different unique wiping lip geometries.
Hydraulic wiper seals is mainly designed for use in heavily polluted environments, especially when the pole is facing upwards. The two wiping lips combine to scrape debris from the rod and contain residual oil on the rod extension.
It is designed to eliminate the debris that accumulates in front of the main wiper lip by forcing it to flow away from the rod to the outside diameter of the cylinder. Wiper seals PT2 design requires two O-ring energizers; One O-ring energizer provides downward force to maintain the engagement of the inner wiping lip, while the other O-ring provides the necessary force and static seal between the main wiping lip area and the sliding surface.
