Description
Product Overview
The O-shaped sealing ring is installed in the gaps of the fuel injector sleeve, high-pressure oil pump chamber, oil circuit connector, sensor base, etc. It achieves sealing through rubber deformation. Under long-term conditions of high cabin temperature, continuous diesel immersion, and repeated high-pressure fuel compression, ordinary rubber is prone to expansion, cracking, and loss of elasticity, leading to oil leakage, fluctuation in rail pressure, and difficulty in cold start. This product uses fluorine rubber with resistance to fuel corrosion as the raw material, with uniform dimensions and outstanding aging resistance. It is a frequently used small part for diesel maintenance and can be purchased separately without the need for a complete maintenance package.
Core Advantages of the Single Item
High-quality green fluorine rubber material, resistant to oil and high temperature, and not prone to deformation
Special fluorine rubber extrusion molding, will not swell or soften when immersed in diesel for a long time, can adapt to the wide temperature range of the cabin, does not crack at high temperatures, does not harden at low temperatures, and maintains sealing elasticity for a long time.
Uniform and regular circular cross-section, no leakage gaps when tightly adhered under high pressure
The sealing ring is of uniform thickness and has no air holes or burrs on the surface. After assembly, the force is uniform, and it closely adheres to the groove under the high-pressure oil circuit, eliminating the possibility of fuel leakage and seepage through fine gaps.
Strong anti-aging and antioxidant properties, longer service life in harsh conditions
Resistant to cabin ozone, high-temperature oxidation, and dust erosion. It is less likely to harden and crack in harsh environments such as mining and long-distance freight transportation, reducing the frequency of replacement costs.
Standardized specifications, universal and compatible for multiple sealing points
Stable size accuracy, can match the fuel injector sleeve, oil pump oil passage, oil pipe connector, and other multiple sealing positions. The inventory of repair stores has strong versatility.
Thorough and defect-free molding process, eliminating internal leakage hazards
Production strictly controls the molding process, with no bubbles or pinholes on the inner and outer surfaces, avoiding oil leakage from the sealing ring's pores.
Batch packaging for assembly, suitable for store and fleet stockpiling
Multiple sealing bags of the same specification are independently packaged. Small-scale replacements and large-scale stockpiling are possible, significantly reducing the cost of sporadic purchases.
