These brass tank connectors provide a quick and easy way of installing additional outlets and connections. Simply drill a suitable sized hole for your tank connector, ensuring you have sufficient flat area all around the hole for the flange of your tank connector to fit flush against the internal wall.
Push your tank connector through the hole from the inside, with the provided rubber washer on the internal tank wall and the male thread of the connector protruding outside. Slip the brass washer over the thread and tighten the nut. You can then attach a fitting with a compatible thread pattern, using PTFE tape to ensure a water tight seal.
