Hydraulic piston PTFE SPGW seal
SPGW Seal is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
|
Advantages:
1.Low friction coefficient
2. Increase in extrusion gaps to a certain extent
3. Excellent extrusion resistance even during pressure peaks
4.Excellent abrasion resistance
