Description
Piston seals SPGO is composed of PTFE seal and O-ring. Double acting piston seal design, with a filled PTFE face ring, provides the designer with a compact, low friction seal for light to medium duty hydraulic cylinders.
For reciprocated hydraulic system, allow large extrusion gap, has wide application, high static and dynamic sealing effect, be able to work in dusty condition, low friction, available in various of materials.
SPGO seals could use for the application of high pressure, low pressure, double-acting reciprocating motions.construction machinery industry, injection molding machine industry,
metallurgical industry, the press industry, engineering machinery oil cylinder factory.
