TPM Combined Piston Seal TPM-393295/393314 - NBR/PTFE Hydraulic Seal for 400 Bar Pressure

Advanced hydraulic piston seal engineered with NBR and PTFE composite materials for demanding industrial applications requiring zero-leakage performance and extended service life.

• Zero-leakage performance for both static and dynamic sealing applications
• Ultra-low friction coefficient reducing energy consumption by up to 80%
• Exceptional extrusion and wear resistance handling pressures exceeding 400 Bar
• Broad temperature compatibility from -30°C to +110°C

• Intelligent three-function architecture combining guide ring, main sealing lip, and elastic compensator
• Self-activating pressure groove design where sealing force increases with pressure
• Advanced friction optimization layer using PTFE materials
• High-strength backing with NBR, FKM, or polyurethane elastomers
• Validated 10 million cycle durability under heavy machinery conditions
• Compatible with biodegradable hydraulic oils for environmental compliance

• Heavy Machinery: Excavator hydraulic cylinders and crane pistons
• Injection Molding: Clamping cylinder precision seals
• Energy Equipment: Wind turbine pitch actuators and oil/gas wellhead controls
• Mobile Machinery: Agricultural steering systems
• Advanced Manufacturing: Die-casting machines and aerospace actuators

Documented case study: Port crane hydraulic cylinder maintenance intervals extended from 6 to 24 months after switching to TPM seals.
