Hydraulic systems demand precision sealing under extreme pressure, temperature shifts, and contamination. Standard rubber seals often fail through extrusion, swelling, or wear—leading to costly leaks and downtime.

The SPGW seal is specially designed for heavy hydraulic equipment and includes a Teflon mixture outer ring, a rubber inner ring and two POM backup rings. The rubber elastic ring provides stable radial elasticity to compensate wear. The use of Rectangular rings of different materials can make the SPGW type adapt to a wide range of working conditions.

Why PTFE SPGW Stands Out:

1.Low friction coefficient

2. Increase in extrusion gaps to a certain extent

3. Excellent extrusion resistance even during pressure peaks

4.Excellent abrasion resistance

SPGW seal specially suitable for bi-directional sealing of piston under high pressure, which improves the oil scraping capacity of SPG.
