Product Description
SPGW Piston Seal for Excavator Cylinders
High-performance PTFE+NBR+NYLON composite seal designed specifically for hydraulic cylinders in excavators and construction equipment.
Product Overview
The SPGW is a double-acting compact piston seal consisting of three components:
- Sealing Ring: Bronze-filled PTFE for low friction and wear resistance
- O-Ring: Nitrile rubber (NBR) or fluororubber (FKM) for elasticity
- Backup Rings: Polyoxymethylene (POM) material for extrusion resistance
Key Features & Benefits
- Excellent dynamic and static sealing performance
- Low friction coefficient with no creeping at startup
- Stable operation across pressure variations
- Resistant to leakage, extrusion, and friction
- Designed for long-distance travel applications
- Suitable for wider piston spacing in various fluids
- Compact structure with excellent overall stability
- Long service life with minimal maintenance requirements
