SPGW Piston Seals Materials:
Sealing ring: filled with polytetrafluoroethylene (F-PTFE)
Elasticity: nitrile rubber (NBR)
Backup ring: modified polyoxymethylene (POM) or modified nylon (PA)

SPGW Piston Seals Features:
Excellent sealing performance in both dynamic and static conditions
Allows for larger extrusion gaps, reducing processing costs depending on the application
Can be safely used in media with contaminants due to the larger extrusion gaps
Low friction and no crawling phenomenon
Simple groove design, suitable for integral pistons
Special requirements please contact TYS team.

SPGW Piston Seals Application :
The t seals of SPGW piston seal excel in hydraulic systems and reciprocating motion applications, particularly in heavy-duty, bi-directional piston sealing scenarios under high pressure, low pressure, and high-frequency conditions. They are suitable for both long and short strokes and can accommodate larger piston clearances in situations involving a wide range of fluids and high temperatures. They are primarily used for piston sealing in heavy-duty or construction machinery, offering excellent leak control, extrusion resistance, and durability, such as in excavators and heavy hydraulic cylinders.
