Description
One PTFE profile ring with a sealing edge and a wiper edge, as well as two O-rings as sealing and pre-load components, make up the Composite Double Wiper Seals PT1. It's a two-o-ring electrified, double-acting rod wiper with two separate wiping geometries. The two lips work together to scrape off debris from the piston rod, contain residual oil in the piston rod extension, and allow oil to be pushed back into the cylinder.
The o-ring energizers provide the force necessary to maintain the engagement of the wiping lips against the sliding surface and allow the wiper to adjust for deflection. The Composite Double Wiper Seals PT1 is capable of high-speed applications and eliminates any potential for stick-slip. High-performance materials provide outstanding wear and scraping capability as well as a large range of temperature and media compatibility.
