56228

Back-Up Ring 56228 is constructed from PTFE to provide reliable anti-extrusion support in high-pressure hydraulic assemblies. Its low-friction characteristics reduce wear on mating surfaces while enhancing overall sealing system durability. Resistant to chemicals, heat, and mechanical stress, it reinforces primary seals and prevents deformation under load. Suitable for dynamic and static applications, this component improves pressure tolerance and extends maintenance intervals.

• Teflon back-up ring prevents seal extrusion under high pressure
• Enhances sealing system durability and pressure tolerance
