Standard short-reach 304 stainless steel radiator filler neck supplied with a low-pressure 4 lb stainless cap—ideal for custom builds and specialist cooling systems.
The 8 mm overflow pipe is supplied loose and must be welded into position when fitting the filler neck to the tank.
This is intentional to ensure a clean weld and avoid contamination from pre-attached parts.
This stainless radiator filler neck and cap set is designed for reliable sealing on pressurised cooling systems where a low-pressure cap is required. Manufactured from grade 304 stainless steel for corrosion resistance and durability, suitable for welding to a radiator or header tank.
Standard short-reach neck. Please measure your existing filler neck to confirm compatibility before purchase.
Enjoy a smooth checkout process. Please ensure the pressure rating and neck dimensions are suitable for your application before ordering.
