Frequently Asked Questions

What are aluminium female weld-on hose fittings used for?
Aluminium female 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 with an internal thread, commonly 1/8"-27 NPT, allowing for the integration of sensors or other threaded fittings in fuel, oil, coolant, and pressurised air systems. These fittings are ideal for custom fabrication projects in motorsport and automotive applications.
What thread sizes are available for these fittings?
Currently, we offer aluminium female weld-on hose fittings with the following internal thread size:
- 1/8"-27 NPT Female
This size is commonly used for integrating pressure or temperature sensors into fluid systems.
Are these fittings compatible with your custom braided hoses?
Yes, our aluminium female 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 female weld-on hose fittings?
Installation involves welding the fitting onto your aluminium component using appropriate welding techniques. Once welded, the internal thread allows for the attachment of sensors or other threaded 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 sensors or fittings connected to them can be detached and reused as needed.
