21513346 Adapter | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta connection adapter used where the engine-specific assembly requires part number 21513346. Its factory dimensions and connection profile provide the correct transition between the adjoining components without altering alignment or sealing load.

⚙️ Key Features

• Genuine Volvo Penta adapter
• Factory-defined connection dimensions
• Maintains correct alignment between mating components
• Suitable for marine or industrial service where listed
• Direct replacement for the same numbered original adapter
• Engine type: Volvo Penta marine or industrial engine system

🔌 Function

Provides the required mechanical or fluid-connection transition between two installation-specific components while preserving factory alignment and sealing.

⚠️ Common Signs of Failure

• Leakage at the mating connection
• Loose fit or inability to retain the adjoining component
• Cracking, thread damage or deformation
• Misalignment after incorrect installation
• Damage to the mating seal or fitting

🛠️ Service Notes

• Check the adapter against both of the parts it has to join before fitting — adapters are specific to an engine and its variant, and one that is close but not correct will not seat or seal properly
• Clean and inspect both mating faces or connector ends; grit, old sealant or corrosion on one side is the usual reason an adapted joint leaks or works intermittently
• Renew any O-ring, gasket or sealing washer belonging to the joint rather than reusing the old one, and lubricate rubber seals lightly so they slide into place instead of rolling or nipping
• Tighten threaded adapters to the figure given in the workshop manual for that connection; many go into aluminium or onto a soft seat and will distort if pulled up hard
• Where the adapter is a workshop tool, check it for thread wear and damage before use and never modify it to make something fit
