Aluminium Port Plugs

Aluminium port plugs are designed to seal off unused or redundant threaded ports in various automotive components, such as oil filter sandwich plates, in-line thermostats, fuel rails, and sensor ports. They prevent fluid leaks and contamination, ensuring system integrity during maintenance or when certain ports are not in use.

We offer the following thread sizes to suit various applications:

• M10 x 1.00
• M12 x 1.5
• M14 x 1.5
• M16 x 1.5
• M18 x 1.5
• M22 x 1.5
• AN3 (3/8"-24 UNF)
• AN4 (7/16"-20 UNF)
• AN6
• AN8
• AN10
• AN12
• AN16
• 1/8"-27 NPT

This range ensures compatibility with a wide array of fittings and systems.

While aluminium port plugs are not typically used with braided hoses, they are fully compatible with our range of custom braided hose fittings and adapters, allowing for secure sealing of unused ports in various fluid systems.

These port plugs are CNC-machined from premium-grade aluminium and finished with a durable black anodised coating, offering excellent corrosion resistance and long-lasting performance in both road and race environments.

Installation is straightforward: thread the plug into the unused port and tighten securely using an appropriate spanner. Ensure the threads are clean and undamaged to achieve a proper seal.

Yes, our aluminium port plugs are designed for easy installation and removal, making them fully reusable. Simply disassemble and use them to block off another port as needed.
