Product introduction
The Cummins G3943549 ensures zero leakage of high-pressure coolant through a multi-layer O-ring and threaded sealing structure. Cummins inlet connection fittings have undergone extreme environment durability testing and are suitable for heavy-duty operating conditions such as mines and ports. X15 Cummins water pipe fittings are critical components of the engine cooling system. Used to connect coolant lines, they are essential for ensuring proper engine heat dissipation and efficient operation.

FAQ
Q: 1. What is the core function of the Cummins G3943549 coolant inlet connector?
A: It uses a high-temperature resistant alloy material and a multi-layer O-ring and threaded sealing structure to ensure no leakage of high-pressure coolant. It is compatible with X15 Cummins water pipe fittings and import connection requirements.
Q: 2. How compatible are the X15 Cummins water pipe fittings?
A: This fitting has a standardized interface, is compatible with the coolant inlet system of X15 series engines, supports quick replacement with original factory repair kits, and has passed extreme environment durability tests. It is suitable for heavy-duty conditions such as mining and ports.
Q: 3. What are the key points for installation and maintenance?
A: During installation, clean the interface surface, tighten the bolts to a torque of 20-25 N·m, and use original factory sealant to enhance the seal. It is recommended to check the seal every 500 hours, and replace the fitting every 2-3 years.
Q: 4. What are the tariff rates for export to the European and American markets?
A:
USA: Approximately 3.7% (HS 8419.10.00)
EU: Standard tariff rate 4.2%, may enjoy preferential treatment under free trade agreements due to CE certification (requires certificate of origin).
Q: 5. What are the requirements for international shipping packaging?
A:We will use shockproof foam + waterproof sealed packaging. For sea freight, we will add desiccant; for air freight, it must comply with IATA non-dangerous goods standards to prevent deformation due to high temperatures.
