With our Tank Connection Sets or our PVC- and PE-Connections, you can easily install an additional connection for inlet, outlet or overflow on the plastic tank. For preparation, drill a hole of the required size in the desired place in the tank. To assemble, unscrew the nut and remove the white ring. Now push the connection with the black rubber seal from the inside of the tank through the prepared hole. From the outside of the tank, place the white ring and tighten the union nut. Please note that the desired connection place can be reached via the inspection opening/lid. For the adaptation, wrap the thread with Teflon tape (approx. 6 windings clockwise) and screw on further articles (e. g. tap, sleeve and hose nozzle). Now you can push the hose on and fix it with the appropriate hose clamp.
