The silicone water transfer connection 3644834 (interchangeable with part numbers 4001402 and 3651300) is an upgraded cooling system fluid connector built for CUMMINS K60 high-displacement diesel engines.
Engineered for Severe Operating Environments & Global Applications
Heavy industrial equipment operating in tropical, desert, or high-altitude mining sites requires coolant connectors that resist intense thermal expansion and atmospheric aging:
- Engine Compatibility: Fits CUMMINS K60 engine units powering haul trucks, large excavators, marine propulsion systems, and continuous-duty standby generators.
- High Thermal Tolerance: Withstands extreme engine bay temperature spikes without hardening or embrittlement, protecting the engine against sudden coolant loss.
- Chemical & Oxidation Resistance: Resists internal scaling, rust particulates, and chemical corrosion caused by industrial heavy-duty coolants.
