TFG Backup Ring – Precision-engineered anti-extrusion ring for sealing system support. Provides rigid backup support to prevent seal extrusion into radial clearances under high pressure and shock loads. Optimized cross-section ensures reliable gap coverage without compromising sealing performance. Wear-resistant compound reduces friction and protects mating hardware surfaces. Suitable as both backup ring and load-bearing support ring in piston/rod assemblies. Ideal for heavy-duty hydraulic cylinders, high-pressure systems, and reciprocating applications. Material: reinforced engineering polymer or PTFE compound. Temp: –40°C to +120°C. Pressure: up to 60 MPa.
