Seal with Backup Ring Solutions | Polypac Hydraulic Seal Solutions

Seal with Backup Ring Overview

Seal with Backup Ring systems are essential for preventing extrusion and extending the life of primary seals in high-pressure hydraulic assemblies. Polypac's Seal with Backup Ring products combine precision-molded elastomeric elements and engineered backup rings to deliver consistent sealing performance across diverse operating conditions. Leveraging our 10,000 m² facility and decades of R&D, Polypac ensures each Seal with Backup Ring meets demanding tolerance, wear, and compatibility requirements.

Key Benefits of a Seal with Backup Ring

The Seal with Backup Ring design dramatically reduces extrusion risk at elevated pressures while maintaining low friction and leak-tight performance. Benefits include improved operational reliability, extended service intervals, and reduced downtime. Polypac integrates material science—NBR, FKM, EPDM, silicone, FFKM—and PTFE composites to optimize the balance between resilience and friction for each Seal with Backup Ring application.

Materials & Customization

Polypac provides custom Seal with Backup Ring options tailored to chemical compatibility, temperature ranges, and dynamic or static service. From bronze-filled and carbon-filled PTFE to MoS2 and glass-filled variants, our material portfolio supports both extreme temperatures and aggressive fluids. Our in-house testing and collaboration with universities ensures every Seal with Backup Ring is validated for performance before delivery.

Applications and Industries

Seal with Backup Ring assemblies are widely used in hydraulic cylinders, valves, pumps, and subsea equipment. Polypac's customers span construction machinery, oil & gas, automotive, and industrial automation—where pressure spikes, thermal cycling, and abrasive media demand robust sealing solutions. We design each Seal with Backup Ring to meet industry standards and customer-specific installation constraints.
