Product Introduction
We have established a complete quality control process system of vee packing hydraulic seals, heavy duty seal SPN, Rubber TC Oil Seals and a full set of after-sales service system, so that our customers can rest assured and worry about product quality and service. We have closely focused on the two central tasks of structural adjustment and transformation and upgrading, and our operating conditions have improved significantly and our profitability has increased rapidly. The group adheres to the business philosophy of "innovation, quality, and efficiency" and the management philosophy of "people-oriented", and treats people sincerely and trusts as a mountain.
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.
