Billet Coolant Fill Port - 1.50" O.D.

This product is exactly what we use in all of our expansion tank delete kits. It allows you to add a remote fill location to your engine. Most people add this into their upper radiator hose for a location to fill, and burp the cooling system. We use and sell these with most of our GM/GMC truck turbo systems. 

Constructed of Billet 6061 areo-space grade aluminum. Included hose-barbs are also CNCed, O-Ring seals for guaranteed leak-free assembly.

The small hose barb is a vent that can be routed to a coolant overflow container.
