Getting rather confused about compression fittings and thread sizings.
Take a 15mm straight coupler, e.g.
http://www.screwfix.com/app/sfd/cat/...88231&id=14921
The internal diameter if the fitting is obviously 15mm, to take
naturally 15mm pipe. But what is the thread size on either end?
Now take something like:
http://www.screwfix.com/app/sfd/cat/...12341&ts=05907
This is described as Female Iron Coupler Compression Fittings 15mm×˝"
The 15mm must relate to the internal diameter and I guess the thread
size is the same on one end as the stright coupler. But what does the
1/2" relate to? The internal diameter on the other end or the thread size?
Help!

The reason for all this is that I am trying to determine whether this:
http://www.screwfix.com/app/sfd/cat/...12341&ts=05907
is the same as this:
http://www.screwfix.com/app/sfd/cat/...76620&ts=07117
but without the flexible hose. Do both items have the same diameters and
threads?
Thanks,
Graham
