Set of Wilo pump unions to connect a heating circulator with G 1½" male thread to a pipe with R 1" (DN25). Handy when replacing a pump: new unions and washers prevent leaks at the pump connection.
Always replace the washers when changing a pump. Close the isolating valves around the pump first and catch the water.
