TFG Backup Ring – High-Strength Anti-Extrusion Support Ring for Hydraulic Sealing Systems.
TFG high-strength backup ring for hydraulic seals. Anti-extrusion, rigid support, low friction. Reinforced polymer/PTFE, –40°C~120°C, ≤60 MPa.
TFG Backup Ring – A precision-engineered anti-extrusion support ring designed to protect hydraulic seals from gap extrusion under high pressure and shock loads. This seal backup ring provides rigid support to the primary seal, preventing deformation and maintaining sealing integrity during pressure spikes. The optimized cross-section ensures reliable gap coverage without compromising sealing performance, while the wear-resistant polymer or PTFE compound reduces friction and protects mating hardware surfaces. The precise dimensional stability ensures consistent performance across a wide temperature range, making this hydraulic support ring ideal for heavy-duty 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.
