Product Description

SPGW Combined Piston Seal1.Standard MaterialSealing ring:F-PTFEElastomer:NBRCheck ring:PA or POM 2.Application Range
Used for hydraulic reciprocating motion systems;heavy-duty bidirectional piston seals under high-pressure condition.It is especially applicable for long stroke and extensive fluids and high temperature occasions, and also applicable to larger piston clearance.It has good performance of leakage control,anti-extrusion and resistance to wear and can be mainly used for oil cylinder pistons sealing of heavy-duty or construction machinery,such as excavators and heavy-duty hydraulic cylinders. Please refer to standards of PHD series of Trelleborg Company,SPGW series of NOK Company,Y3 series of Parkrt Company and KHD series of AS Company when designing and selecting.3.Features(1)Good dynamic and static sealing performance(2)Simple groove structure(3)Allow larger extrusion gap(4)Long service life(5)Little static and dynamic friction coefficient and low wear(6)No crawling while starting up and can work stably(7)Owing to larger extrusion clearance,it can be safely used in the Medium with sewage4.Product Introductionhe SPGW Combined Piston Seal is a high-performance, double-acting compact sealing solution engineered for heavy-duty hydraulic cylinder pistons, comprising a filled PTFE sliding ring, a profiled elastomer energizer (NBR/FKM), and two anti-extrusion backup rings (POM/PA). As a premium integrated sealing system, it delivers exceptional leak control, extrusion resistance, and low-friction performance in extreme high-pressure reciprocating motion applications, making it the gold standard for bidirectional piston sealing in heavy construction machinery, mining equipment, and industrial hydraulic systems requiring long service life and minimal maintenance. It is the core sealing component for medium-to-large hydraulic cylinders demanding reliable performance under dynamic pressure fluctuations and harsh working conditions.
