SPGW Bronze Filled PTFE Piston Seal is a high-performance hydraulic piston ring designed for demanding industrial applications. Engineered with bronze-filled PTFE material, this seal delivers exceptional durability and reliable performance under high-pressure conditions.

• Low coefficient of friction with excellent abrasion resistance
• Two modified plastic back-up rings prevent extrusion
• Initial shrink range design ensures sealing performance at low pressure
• Rectangular geometry provides exceptional stability

• Superior extruding resistance for seals and elastomers
• Oblique radial incision for easy installation and prevention of elastomer breakage
• Functions as wiper seal to remove internal contaminants
• High elastic modulus materials maintain rigidity under high pressure and temperature
• Rounded corners prevent elastomer damage

• T-form elastomer design prevents crimping
• Back-up ring integration eliminates extrusion issues
• Initial pre-tightening force ensures reliable sealing across pressure ranges
• Optimized geometry enhances stability and leakage control
• Chamfered elastomer design saves space and reduces back-up ring load
