⚙️ Key Features

• Genuine Volvo Penta 2-inch seawater hose connection
• Used in raw-water intake and strainer assemblies
• Correct internal bore for high-volume cooling-water flow
• Two connections used in specified installations
• Compatible with the associated Volvo strainer and valve hardware
• Engine type: Volvo Penta marine diesel with seawater-cooled heat-exchanger circuit

🔌 Function

Provides the sealed transition between the flexible seawater hose and the rigid strainer/valve assembly so the raw-water pump receives unrestricted cooling-water supply.

⚠️ Common Signs of Failure

• Water leakage or salt deposits around the joint
• Corrosion, cracking or damaged hose-barb surface
• Hose loosening or repeated clamp movement
• Restricted flow from internal scale or marine growth
• Air entering the suction side and causing poor seawater-pump priming

🛠️ Service Notes

• Check the connection and the hose bore are clean and undamaged, and push the hose fully onto the spigot past the bead before clamping
• Position the clamp on the parallel part of the spigot behind the bead, and tighten it enough to seal without cutting into the hose
• Renew the O-ring, gasket or sealing washer where the connection screws or bolts into a housing, and check the thread and the seat are clean and dry
• Support the pipework so the joint is not carrying the load or the pull of the hose — a connection loaded sideways will weep
• Fill, vent and pressurise the system, then check the joint cold and again at operating temperature, retightening the clamp if it has taken up
