Description
Product Overview
The O-ring serves as a sealing component for the oil passage and cavity gap, filling the metal assembly gaps and preventing high-pressure fuel leakage and hot gas intrusion. Under long-term conditions of high cabin temperature, prolonged exposure to diesel, and continuous oil pressure shock, ordinary rubber rings tend to expand, harden, and crack, resulting in oil leakage, unstable rail pressure, and dilution of engine oil. This product is made from special fluorine rubber material, which is resistant to diesel, high temperatures, and has excellent anti-aging properties. The dimensions are uniform and standardized, suitable for multiple sealing points on oil pumps, injectors, and oil passage connectors. It is a frequently used consumable part for diesel fuel system maintenance.
Core Advantages of the Single Product
High-quality green fluorine rubber base material, resistant to oil and temperature, and not prone to swelling
Special fluorine rubber is extruded as a single piece, able to withstand long-term immersion in diesel and hydraulic oil, does not soften or expand in high-temperature environments, and does not crack in low temperatures. The sealing performance remains stable over a long period.
Uniform circular cross-section, no leakage when fitting the sealing gap
The cross-section is uniform without burrs, and after assembly, the force is distributed evenly. Under high-pressure conditions, it closely adheres to the metal groove, eliminating fuel leakage and oil pressure relief from tiny gaps.
Long-lasting and durable, suitable for harsh cabin conditions
Resistant to ozone and high-temperature oxidation, it does not harden or crack in environments with alternating cold and hot temperatures and dust, significantly reducing the frequency of repeated repairs and replacements.
Standardized unified dimensions, suitable for multiple parts
The specifications and sizes are precise and unified, and can be used for multiple sealing points such as injector sleeves, high-pressure oil pump cavities, oil passage connectors, and sensor bases. The inventory is versatile and suitable for general use.
Smooth surface without air holes, no oil leakage risks
During the production process, the molding process is strictly controlled, ensuring that the inner and outer surfaces of the sealing ring are dense without pinholes or bubbles, preventing high-pressure fuel from leaking through the internal pores of the rubber ring.
Batch packaging for supply, lower storage costs
The same specification is packaged as a complete set for shipment, suitable for repair stores and fleets to stock in bulk. It is convenient for single-piece loss replacement without the need for a complete set of repair kits.
