Details

Standard overflow fittings often have a rigid 21.5mm size that will not fit older 19mm pipes or slightly larger 23mm variants, and this often leads to frustrating compatibility issues on-site. Additionally, solvent-weld connectors require a perfectly clean and dry surface to bond, which is almost impossible during an active leak. This McAlpine Universal Connector solves these problems because the tapered compression seal adapts to fit almost any common overflow pipe size. Moreover, the hand-tightened nut creates an instant, mechanical seal even on damp or slightly mismatched pipes. Therefore, you eliminate the guesswork from your repairs while you secure a permanent, professional-grade connection.
