CUMMINS
4988138 quick connect fitting is a precision pipeline joint component designed for Foton commercial trucks matched with Cummins diesel engines. Widely applied in engine cooling circuits, fuel delivery lines and pneumatic system pipelines, this quick connector realizes fast locking and disconnection of fluid pipelines without auxiliary tools. It effectively solves common pipeline faults such as joint loosening, fluid leakage, pipeline shedding and poor sealing caused by aging, deformed and rusted traditional threaded joints, ensuring stable and safe operation of engine fluid transmission systems during long-term full-load transportation.
1. Tool-Free Quick Installation: Innovative push-in locking structure enables fast pipeline connection and disassembly, greatly shortening maintenance time and improving workshop repair efficiency.
2. Excellent Leak-Proof Sealing Performance: Built-in high-elastic precision sealing ring provides 360° uniform compression, effectively prevents coolant, fuel and air leakage under high pressure and vibration conditions.
3. High Pressure & High Temperature Resistance: Adopts high-strength engineering material and reinforced locking structure, stably withstands engine high temperature and pipeline working pressure, no deformation or failure under continuous operation.
4. Strong Vibration & Impact Resistance: Optimized anti-loose locking design avoids joint loosening and pipeline shedding caused by engine resonance and bumpy road vibration, improving driving safety.
5. Anti-Aging & Anti-Corrosion: Special surface treatment resists engine oil erosion, antifreeze corrosion and dust oxidation, adapting harsh engine compartment working environment and extending service life.
6. Precise Size Compatibility: Standard interface caliber and locking stroke perfectly match Cummins engine pipeline specifications of Foton trucks, supporting direct plug-and-play replacement without cutting or grinding.
7. Strict Factory Quality Control: Finished products pass high-pressure sealing test, temperature cycle test and vibration fatigue test, with stable batch quality for fleet regular replacement and bulk wholesale procurement.
