Description
Product Overview
The sealed O-ring is assembled into the installation groove of the electronic fuel injector body. After assembly, it fills the clearance between the fuel injector and the cylinder head, preventing high-pressure fuel from leaking out and preventing the hot gas in the combustion chamber from flowing back into the fuel line. Under the long-term alternating cold and hot cycles of the engine, long-term immersion in diesel, continuous vibration of the engine compartment conditions, ordinary rubber rings are prone to hardening, expanding, losing elasticity, and resulting in sealing failure and leakage. This product strictly controls the dimensional tolerance, is compatible with the corresponding model fuel injector sealing groove, and can be replaced simultaneously when removing and installing the fuel injector, eliminating oil leakage and intake pressure relief faults. It is suitable for large mining excavators, heavy-duty loaders, and long-distance trucks with electric fuel injection common rail diesel engines for maintenance and repair.
Core advantages of the product
Made of oil-resistant fluorine rubber material, it does not expand or harden when soaked in diesel for a long time.
It is molded using a special fluorine rubber raw material for fuel resistance, and can withstand long-term immersion in various types of diesel and engine oil. It will not expand, crack, or harden in wide temperature ranges, maintaining long-term sealing rebound performance.
Uniform standard circular cross-section, fits the sealing groove without leakage gaps.
It is molded as a whole, with uniform thickness and no eccentric core, and fills the gap of the fuel injector sealing groove after being inserted, without compression skewing under high-pressure conditions, and preventing fuel from leaking through the assembly gap.
High rebound compression characteristics, maintaining sealing force even after repeated assembly and disassembly.
The rubber molecular structure is optimized, with a high compression rebound rate. Even after repeated squeezing of the fuel injector after multiple replacements, it will not permanently deform. A single replacement can provide long-term stable sealing, reducing the cost of frequent replacement of consumables.
Resistant to high temperature and aging, preventing damage from high-temperature radiation in the combustion chamber.
It can withstand the heat transmitted by the cylinder head and will not rapidly age and fail under long-term alternating cold and hot cycles. It prevents the high-temperature gas from directly burning the rubber body, extending the service life of the sealing component.
Uniform standard inner and outer diameter sizes, no assembly jamming.
The inner and outer diameters and wire diameters are standardized processed, with a very small tolerance range. It fits smoothly into the fuel injector body without sticking, eliminating the need for manual cutting and polishing, and the disassembly and assembly operations are convenient.
Sealing durability inspection for batch production, consistent performance in the same batch.
Samples of sealing rings are taken from each batch for high-pressure pressure retention, high-temperature cycle durability tests. The performance parameters are consistent, and the oil circuit sealing state can be quickly restored after maintenance and replacement.
