SPG Seal for hydraulic Piston

Features:

ZDSPG type piston seal is composed of PTFE piston seal ring and rectangular ring, and is used for bidirectional sealing of the piston of hydraulic cylinders. The use of specially modified PTFE material ensures excellent low friction, wear resistance, extrusion resistance, high temperature resistance and chemical corrosion resistance. Rectangular rings can provide elasticity to compensate for wear more smoothly than O-rings. The use of rectangular rings of different materials can ensure a wide range of operating temperature range. ZDSPG is a combination seal used in a wide range of applications, especially suitable for controlling cylinders and servo systems. , machine tools, fast response cylinders and two-way piston cylinders in construction machinery.

Material:

-- The wear ring is made of PTFE bronze composite material;

-- The rectangular ring is NBR;
