This beautifully machined radiator filler neck is robust and Australian made.
Aluminium construction allows welding directly to radiator header tanks or even to complex feeder or air release tanks.
Easy to weld and compact, this neck suits a range of common radiator caps available at many automotive outlets.
Often, we use a Stant radiator cap with a lever release with this type of filler.
The 1/8npt barb is provided and is used to run an overflow line, suitable for a 5/16 hose. We generally use transparent plastic line on our racecars to save weight and to easily monitor any overflow from expansion.
For convenience the 1/8npt barb comes with unit but is not tightened into the assembly - install and tighten barb once welded.
Sold each, as shown in pictures.
