Overview
Running fuel through high-pressure injection pumps takes a toll on standard elastomers. Engineered from fluoroelastomer with a PTFE exterior coat, this seal slides into grooves without bunching or shearing during assembly. The compound handles hot diesel and high cyclic pressures while resisting compression set over thousands of service hours.
Features
- 13.94 mm inside diameter
- Fluoroelastomer (FKM) core with PTFE anti-twist coating
- High resistance to compression set and fuel degradation
- Precision cross-section for injector and pump cavity sealing
Applications
Fits inside fuel injection pump valves and unit injector housings to seal high-pressure diesel lines.
