howdy

I have a 28 mm compression coupling into which I need to put a 22 mm
pipe.

I have bought a 28 to 22 mm reducer (in profile looks like a fat
bottle - with a 22 mm neck and a 28 mm body)

The question is - do I need to solder a 28 mm pipe onto the reducer
and then put the 28 mm pipe into the compression coupling - or can I
put the 28 mm "body" of the reducer straight into the compression
coupling . I'm wondering if the reducer is too weak to go into the
compression coupling ?

cheers
