Designed as a genuine OEM replacement, this elbow fitting provides a secure connection for cooling system hoses and helps maintain proper water circulation throughout the engine and exhaust system.
Cooling system fittings are essential for directing water flow through marine engines and related components.

Replacing damaged hose fittings helps prevent leaks, maintain cooling system pressure, and support reliable engine performance on the water.

Its compact angled design allows for efficient hose routing in tight engine compartments while maintaining smooth water flow through the cooling system.
