Genuine Merrill G-41 brass valve body. This valve body has the 1 inch supply inlet and is for the 1inch Industrial Merrill Anyflow Yard Hydrant with the threads on the red cast iron spout. This valve body will not work for the 3/4 inch Anyflow hydrants. The valve body will also have a small weep hole located in the side of the valve body. The weep hole is designed to insure all of the water drains out of the hydrant.
