Yale Unions

Our Yale union design allows valves and other fittings to be removed easily from the production line.

The ease of removal of our Yale union from the production line offers an advantage when installing the fitting in a short section of line, as it is not necessary to “spread” or bend the line when removing the fitting. Our unions can be manufactured to your material specifications: carbon steel, alloy steel, or ductile iron.
