Multifit Connections

Multifit Connections

  • Most McAlpine Trap Outlets and Fittings have Multifit Connections.
  • Multifit Connections suit all plastic waste pipes to BS EN 1451-1-2000 and BS EN 1329-1:2000, copper pipe (metric or imperial) and lead pipe.
  • The moulded Internal Sleeve of the Connection, centres and supports the pipe.The Multifit and Friction Washers ensure a secure seal is made between the pipe and the wall of the Fitting. When the compression nut is turned hand tight the best possible mechanical joint is complete.
  • If a plastic pipe is undersize, or out of shape, the end may require to be warmed to enable it to be pushed over the internal sleeve.
  • For technical reasons, it is not possible to manufacture Multifit Connections on all traps and fittings. Where Multifit is not provided the description Universal is applied. The only difference being that Universal does not have an Internal Sleeve within the Trap or Fitting.
