SPGW Piston Seal Fits Excavator

SPGW Piston Seal Fits Excavator
SPGW, one of important parts for machines, is a heavy-duty two-way piston sealing ring widely used in high-pressure conditions. It has excellent anti-leakage, anti-extrusion and wear resistance properties. It is especially suitable for long-stroke conditions, and for a wide range of fluids and high temperature occasions, and can be adapted to larger piston gaps. It uses a unique sealing material and geometric shape. It is a polytetraethylene combined sealing ring made of elastomer, and is superimposed to form a compact structure with good performance and can be installed in a single piston groove. Its geometry makes it have overall stability, wear resistance, good sealing, low friction and long life without maintenance.
