Needs a ½” NPT to ½” barb fitting to connect to ½” ID HT tubing. Typically want to use HT tubing rated for at least 200 degrees C on the pump, which is either thermoplastic (rigid) or silicone (flexible). The pump is magnetic driven, so needs to be below the kettle for gravity feed to start pumping (priming). You can also use an inline valve on the out-flow side of the pump to throttle the flow if needed. Really just hook it up and plug it in to run.
