Default Joining metric to Imperial pipe.

I want to join 15mm copper pipe to another pipe which is Imperial
polyethylene, Class C, low density to BS 1972/67, and installed around
1968.

This polyethylene pipe is of nominal size half inch, with an outside
diameter of 21.5mm, wall thickness a little under 3mm. It is black in
colour, and is to be used overground.

For the connector, will it be all right to use a metal (such as
Kuterlite) 22mm to 15mm reducing fitting, with a three-quarter inch
imperial copper olive at the 22mm end going over the polyethylene pipe? I
have a metal pipe insert available that was left over from when the pipe
was originally installed in around 1968.


Sounds like it ought to be ok. Failing that BES do transition fittings
that will mate with all sorts of pipe including lead. iron, plastic etc.,
and each one covers quite a range of sizes.

Thanks John for your thoughts. I shall probably go ahead and see what
happens, as you think it may well be all right.

I have since discovered that Kuterlite list a fitting, K1710KP that is
marked Polyethylene to Copper,1/2 inch x 15mm, which seems to be made for
this job, but I have not yet found anyone who sells them singly. And the BES
fittings are a bit more bulky than the Kuterlite type and I have got limited
space to get the fitting in.
