Orifice Union

FPPI's ½" IPS Brass Union with Orifice is specifically designed for use in the pressure sensing line for fire pump systems. The union is fitted with a ¼" orifice which will provide adequate pressure drop into the sensing line without allowing unnecessary pump starts due to major pressure fluctuations that may be indicated in the larger diameter (½") line. The union is only allowed to be used where the water is clear and will not allow sediment to block the ¼" hole. Check with pump manufacture for proper use.
