Heavy-duty 304 stainless filler neck with matching short-reach pressure cap—ideal for custom radiator/header tank builds and repairs.
This stainless steel radiator filler neck and cap set is designed for secure, reliable sealing on pressurised cooling systems. The neck is manufactured from 304 stainless steel for corrosion resistance and long service life, and is suitable for welding to a radiator or header tank.
Please note: The 8 mm overflow is loose in the neck and will require welding in position prior to welding the neck to the radiator or header tank.
Tip: Please ensure you are matching the cap reach/style to your application before purchase.
