Our straight or bend PVC tank connection Sets, consisting of a PVC tank connection, a PVC socket or knee socket and a PVC hose tail, allow you to install an additional hose connection on the water tanks. Always use the inside diameter of the hose to be installed as a guide, e.g. for inlet, outlet, overflow, vent, etc. When installing the PVC Tank Connection, ensure that the location for the required connection area can be reached via the tank lid. The PVC Connection is fed from the inside to the outside through the hole in the water tank/plastic tank and must be held against it from the inside to screw it on from the outside with the lock nut. We offer PVC tank connection sets in straight and bend versions for hoses with inner diameters of 13, 25, 30, 40, 50 and 63 mm.
