Our aluminium weld on bosses are an excellent accessory for any aluminium pipe that you wish to modify. The broad flat seat of our aluminium bosses allow for a clean, tidy and easy weld. Specially designed, CNC machined and with a polished finish, these bosses are of the highest quality.

We offer bosses in number of outer diameters and usually have them in stock, ready for fast delivery. Aluminium bosses are ideal for adding a breather onto a pipe. We have available barbed, male AN threaded and female BSP threaded weld-on bosses to suit a variety of needs and applications. We also also offer a variety of other parts and components, perfect for silicone hoses and aluminium pipes, which you can also buy from our professional and diverse product range.
