Standard Materials:

Sealing ring: filled with polytetrafluoroethylene (F-PTFE)
Elasticity: nitrile rubber (NBR)
Backup ring: modified polyoxymethylene (POM) or modified nylon (PA)

Features:

• Excellent sealing performance in both dynamic and static conditions
• Allows for larger extrusion gaps, reducing processing costs depending on the application
• Can be safely used in media with contaminants due to the larger extrusion gaps
• Low friction and no crawling phenomenon
• Simple groove design, suitable for integral pistons
• If there are special requirements (pressure, temperature, speed, special media, etc.), please contact our consulting service department for recommendations on suitable materials.

Application Scope:

These seals excel in hydraulic systems and reciprocating motion applications, particularly in heavy-duty, bi-directional piston sealing scenarios under high pressure, low pressure, and high-frequency conditions. They are suitable for both long and short strokes and can accommodate larger piston clearances in situations involving a wide range of fluids and high temperatures. They are primarily used for piston sealing in heavy-duty or construction machinery, offering excellent leak control, extrusion resistance, and durability, such as in excavators and heavy hydraulic cylinders.
