DAVIES CRAIG Air Bleed Fitting 1/4" NPT (10412)

AIR BLEED FITTING ¼" NPT - PART #10412

To assist expel unwanted air from the engine’s cooling system, following the fitment of a Davies Craig Electric Water Pump an Air Bleed Fitting is now available. This fitting offers a simple method that helps ensure all air can be removed. The ¼” NPT threaded brass fitting has a bleed screw which can be opened. When coolant begins to flow, all air should have been removed from the system and the bleed screw closed.

Air Bleed Fittings are not common on modern day vehicles and are an added convenience to rid the cooling system of air pockets when trapped in the system. Air in any cooling system can lead to an overheating engine.

The Air Bleed Fitting should be installed in the top radiator hose at the highest point of the cooling system. This Fitting can be used in conjunction with the Nylon Adaptor, Part # 10415 and Parts #18510 3mm (1/8”) Rubber Sleeves or #18511 6mm (¼”) Rubber Sleeves for radiator hoses up to 50mm (2”) ID diameter. Removing the air and allowing coolant to displace it allows the cooling system to function more efficiently.
