About Piston Seals
 

This type piston seal is  double-acting (pressure acting on both sides) seals.   features a polyether-based polyurethane (EU) slide ring that is hydrolysis-resistant (moisture-resistant) and has good low-temperature flexibility. O-ring energizers provide a cost-effective sealing solution. Developed for pressures up to 250 bar (3 625 psi), suitable for light /medium  duty applications. applications such as agricultural and material handling applications. They are available in metric sizes and some fit seal housings that comply with ISO 7425-1.

It 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 .
