SPG Piston Composite Seal

SPG is a compact double-acting piston seal for medium to heavy duty applications.

The reinforced, thermally stable thermoplastic sealing surface with stepped joints allows the seal to pass through the port, making it ideal for double acting telescopic cylinders.

Description

Structural Design:

It consists of a bronze-filled PTFE face ring preloaded by a square-section NBR ring.

Due to the fact that only the PTFE face ring is in contact with the sliding surface, the friction force is very low and the stick slip motion is eliminated.

SPG piston seals have extremely low friction resistance, eliminating crawling and ensuring high wear resistance.

 

Summary of Advantages:

  • High static and dynamic sealing effect
  • High resistance to extrusion
  • low friction, high efficiency
  • no sliding start, no adhesion
  • High wear resistance and high operational reliability

Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
