Connecting to old 1inch copper

[CAESAR32]

hey is it ok to connect old 1inch copper to 28mm copper via 28mm Yorkshire or end feed fittings or a 28mm compression fitting?

No, you need adaptor, or it will be too sloppy.

it will not be sloppy it will be tight 1" is slighly bigger 28mm fitting will go with a bit of force
Ive never needed to use an adaptor !

So 1 inch is bigger than 28mm is it?? Is that a metric inch, or imperial?

Try this and get back to me.

old inch pipe is bigger than 28mm pipe, conex connectors dont fit, Endex can be forced

right im getting back to you !!
this post is about pipe sizes not converting measurements

imperial pipe is measured ID metric is OD !!

1/2" and 15mm
1" and 28mm
2" and 54mm
will all fit

Ok, That makes sense. Looks like I've been wasting money on those metric to imperial connecters then.

 

[newbuildinstaller]

15mm and 28mm will mix and match WHEN FORCED!

3/4 is noticeably smaller than 22mm

Socket form it to what ever size you like, plumbers arguing about new/old

No it doesn't. We're designing and installing water carrying systems. We need to be calculating using the bore of the pipe, so 1/2" 12.7mm 1" 25.4mm whatever! Whoever thought in the 60's it was a good idea to start referring to everything by outside diameter? What good's that to an engineer?

You don't see electricians ordering by the diameter of the cable, it's by the cross-sectional area of the copper. That's the most important aspect, what you require for the flow/pressure loss, whether it's water or electrons!

You got a 54mm socket former gav????

22mm don't fit
35mm don't fit
42mm don't fit
54mm don't fit......depends on kahoonas.

15/28 will fit......

!

So 22mm copper tube is not refered to by its outside diameter? nor 15mm? or maybe 28mm?

Imperial to metric tube came about in the early 70's , not to be confused with currency.

Of course they are, that's my point!

No, sorry sausage, have you got a career looking after you?

PMSL THAT SOMEONE CAN BE ADAMANT THAT 28 DONT FIT INCH and has been buying adaptors most people would just have tried it and seen if it fitted.

Fekin basic
