Product Introduction

With the strong strength of our Hydraulic Piston Seals Double Delta, guide ring seal, skeleton oil seals industry, our company has formulated a strategic plan for the medium and long-term sustainable development of the enterprise. Quality over profit, brand over speed, and social value over corporate value are the tenets we have been adhering to. In the fierce competition in the market, our company has always insisted on pragmatic work to give customers peace of mind. We have now formed a complete product structure that can meet the processing of various products.

Description

Step seals is composed of a rubber O-ring and a PTFE ring. The material is PTFE+NBR. In special cases, rubber will be used FKM. It can be divided into rod step seals and piston step seals, but the sealing effect is same.

According to its own deformation, will generate a higher initial contact stress on the sealing surface, prevent liquid leakage. When the hydraulic cylinder is working, the pressure fluid is elastic deformed through the O ring, maximize squeeze the square ring, making it close to the sealing surface, generated high additional contact stress and increased the pressure of the pressure liquid. Together with the initial contact stress, the leakage of the pressure liquid is prevented.

The installation physical performance of the rod step seals is stable. It has good dust-proof effect and is not easy to be invaded by foreign objects. Can prevent all external interference. Rod step seal has the characteristics of long service life, strong extrusion resistance and high wear resistance.
