⚙️ TECHNICAL SPECIFICATIONS
Technical Detail
Measurement / Info
Component Product Profile
High-Pressure Injection Pump Interface Sealing Ring / O-Ring
Material Matrix Formula
Premium High-Fluorine Elastomer (Engineered to withstand ultra-low sulfur diesel, bio-diesel variations, and continuous contact with hot engine oil without swelling or shrinking)
System Sealing Strategy
Establishes a precise fluid barrier at the high-pressure injection pump mounting flange, keeping the internal pressurized fuel system completely isolated from the engine gear housing.
Operational Focus
Prevents dangerous external fuel weeping and stops low-pressure fuel delivery circuits from drawing in air pockets, which would disrupt steady common rail pressure and cause erratic idling.
Maintenance Directive
Single-use component. Always renew this seal whenever the high-pressure injection pump is extracted for testing, system cleaning, gear alignment, or pump replacement.
Quality Seal
ELRING – Das Original (Certified Premium Commercial Diesel Pump Fluid Isolation)
