Piston Seal SPGW Compact Seals SPGW Hydraulic Seals for
Construction Mechanical
Description
SPGW seal is suitable for use in reciprocating hydraulic cylinders.
It has double sealing performance under high load and high pressure
working environment. Especially suitable for long time and high
temperature environment. Simple trench structure.
SPGW seals are designed for double-acting hydraulic cylinders used
in heavy-duty hydraulic equipment. It is ideal for heavy-duty
applications and ensures high maintainability. It consists of a
Teflon compound outer ring, a rubber inner ring and two nylon
support rings. Rubber elastic rings provide stable radial
elasticity to compensate for wear. The use of rectangular rings of
different materials allows the SPGW model to adapt to a wide range
of working conditions. It has the advantages of wear resistance,
impact resistance, high pressure resistance, and easy installation.
