Details

Standard tank connectors often have a rigid 21.5mm entry that fails to grip older 19mm pipes or slightly larger 23mm variations, and this often leads to slow, persistent leaks that damage floorboards or lofts. Additionally, low-quality connectors often have thin seals that perish or slip during installation, which forces you to redo the entire job. This McAlpine R4M Connector solves these issues because the tapered internal seal grips the pipe with total precision regardless of the diameter. Moreover, the heavy-duty flange and washer create a robust, physical barrier that holds firm even under water pressure. Therefore, you eliminate the risk of water damage while you enjoy the peace of mind that comes with a professional-grade McAlpine fitting.
