Frequently Asked Questions

What are aluminium male weld-on hose fittings used for?
Aluminium male weld-on hose fittings are designed to be permanently welded onto aluminium components such as tanks, pipes, radiators, and intercoolers. They provide a strong, leak-free connection point for AN-style hoses in fuel, oil, coolant, and pressurised air systems, making them ideal for custom fabrication projects in motorsport and automotive applications.
What sizes are available for these fittings?
We offer aluminium male weld-on hose fittings in the following AN sizes:
- AN4 (7/16"-20 UNF)
- AN6
- AN8
- AN10
- AN12
- AN16
- AN20
This range ensures compatibility with various hose diameters and system requirements.
Are these fittings compatible with your custom braided hoses?
Yes, our aluminium male weld-on hose fittings are fully compatible with our range of custom braided hoses, including those used for fuel, oil, coolant, and pressurised air systems. They ensure a secure, leak-free connection in high-performance environments.
What materials are these fittings made from?
These fittings are CNC-machined from high-grade aluminium and have a raw silver finish, offering excellent corrosion resistance and long-lasting performance in both road and race environments.
How do I install these aluminium male weld-on hose fittings?
Installation involves welding the fitting onto your aluminium component using appropriate welding techniques. Once welded, the external thread allows for the attachment of AN-style hose fittings. Ensure all connections are tight and leak-free before pressurising the system.
Are these fittings reusable?
While the fittings themselves are permanently welded onto components and thus not reusable in other applications, the AN-style hose fittings connected to them can be detached and reused as needed.
