About Piston Seals
This type piston seal is double-acting (pressure acting on both sides) seals. suitable for medium / heavy duty applications.
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 .
