Restricting Orifice Union

Our ½” restricting orifice unions are designed for use in the pressure sensing line for fire pump systems and jockey pumps to provide adequate pressure drop.  The union is only allowed to be used where water is clear and will not allow sediment to block the 3/32” orifice.
