Product introduction
The Cummins oil hose, model 4319298X, is specifically designed for the Cummins QSB5.9 series. Its pressure and flow rate are perfectly matched to the original vehicle's oil line interfaces, eliminating the risk of leaks and incorrect installation. It is the only officially recommended replacement for Cummins engine oil lines. The 4319298X Cummins hose features a fluororubber inner layer and nylon braided reinforcement, allowing it to withstand extreme operating conditions from -40°C to +150°C. Its resistance to fuel corrosion far exceeds that of ordinary rubber hoses, and its service life is more than twice the industry average. It is an indispensable component in Cummins engines!

Product Advantages
As a genuine Cummins part, the 4319298X engine utilizes unibody casting technology (such as integrating the water pump and oil pump housing with the cylinder block), reducing the number of parts and potential leak points. The oil lines employ high-quality materials and reliable connection processes to withstand high pressure, high temperature, and vibration. The engine is designed with oil-water separators to enhance its adaptability to various oil types. The oil piping system ensures smooth oil flow and stable pressure in harsh environments such as extreme cold, high temperature, and high altitude.
FAQ
Q: 1.Which Cummins engines is the 1.4319298X oil hose specifically designed for?
A：It is specifically designed for Cummins QSB5.9 series engines, such as QSB5.9-C180/C210/C250. It is not suitable for other 5.9L engines such as ISB5.9 or B5.9. Ensure the interface is completely compatible with the pressure system.
Q: 2. Is it necessary to apply sealant or lubricant during installation?
A: The use of sealant or lubricant is strictly prohibited. The original hose is self-sealing; applying sealant will cause oil contamination and seal failure. Only use the original clamps and tighten according to specifications.
Q: 3. What are the maximum operating temperature and pressure resistance of this oil hose?
A:It uses a fluororubber inner layer, with a temperature range of -40°C to +150°C and a maximum pressure resistance of 31.5 MPa. It can stably withstand high-pressure fuel circulation and the high-temperature environment of the engine.
Q: 4. What customs clearance documents are required for exporting this oil hose?
A:We will provide a commercial invoice, packing list, and Chinese certificate of origin, declared as "parts for diesel engines" according to HS code. The document information must be completely consistent with the packaging label.
Q: 5.Is this product a dangerous good? Can it be transported by air?
A:It is not a dangerous good, contains no flammable, explosive, or toxic components, and can be safely exported by sea or air. However, there must be no residual engine oil or oil stains inside the packaging to prevent it from being mistakenly identified as contaminated goods.
