McAlpine bowl and a half kitchen sink plumbing kit with one connection for the discharge from domestic appliance.
Standard 1-1/2" BSP inlets and compression type outlet connection.
The threaded part(s) of this item is made to a British Standard Pipe Thread size (BSP). BSP sizes don’t match up with what you would measure using a ruler, which can obviously cause some confusion. Have a look at the BSPT link at the bottom of this page for more information.
