McAlpine Fittings – Why are they the plumbers first choice?

McAlpine started making plumbing products in 1902 and later were the first company in the UK to manufacturer plastic traps so its fair to say they know how to make a decent fitting or two. Now a days they make everything from traps to toilet pan connectors.

Today we’re talking about waste traps and fittings, now McAlpine fittings use what’s called a compression coupling, what this is is a rubber washer that is slid on to the end of the pipe and then is crushed by the nut when you put in to the fitting to create a firm seal. McAlpine have their own guide which you can find here

With traps there are 3 main sizes: 32mm, 40mm and 50mm

  • 32mm or 1.25 inch is designed for basins and bidets
  • 40mm or 1.5 inch is designed for kitchen sinks and baths
  • 50mm or 2 inch is designed for commercial kitchen sinks
