Product Description

About Piston Seals
 

Piston seals are typically classified into single-acting (pressure acting on one side only) and double-acting (pressure acting on both sides) seals.  suitable for light / medium / heavy duty applications.  

Piston seals could  keep  the contact between a piston and cylinder bore , the work life of  seal  is decided to different media ,various temperatures, surface finish properties and stroke  speed.

Our premium grade material  bring  lower  friction and lower leakage by  managing the lubrication film thickness, higher density material offered by CNC process  also ensure the lower extrusion length and longer lifetime at the same working condition . 

   

Ordinary Piston Seal Section:

Due to our unique mahcined process, in addition to the above ordinary cross-sections, we can machined seals of any size and material according to customers' customized drawings.
