HOSE ADAPTER 38-29mm

Function and technical context

This 38 to 29 mm hose adapter is part of the water cooling circuit of outboard and stationary marine engines, allowing the transition between pipes of different diameters without flow losses or leaks. Its function is to connect sections of hose from different sections within the cooling system, ensuring the necessary tightness so that the cooling water circulates correctly to the exchanger or cylinder head. A damaged or cracked adapter can cause a drop in coolant flow, with the consequent risk of engine overheating and damage to head gaskets or other internal components. The reference RU67 uniquely identifies this part to facilitate its exact location and replacement during any intervention in the engine's hydraulic circuit.

When to replace this part?

The most common symptoms of a hose adapter in poor condition are the presence of moisture or traces of lime in the connection area, hoses that come loose easily or visible water leaks in the engine compartment, especially after cold starts or at full speed. It is recommended to visually inspect this component during each seasonal maintenance, paying special attention to hardening, cracking or deformation of the adapter due to temperature and salt. Replacing it preventively at the slightest sign of deterioration prevents more serious navigation breakdowns and protects the integrity of the entire cooling system.
