eg item code 56343 (page 461) which is a Cu solder ring15mm slip
coupler.

What is a 'slip coupler' as opposed to just an ordinary straight join?

TIA for explanation.

one that has no central ridge so it can be slipped entirely onto a pipe
when inserting a new section of pipe into a run.

I wondered this some while ago.

It's one that has no 'shoulder' inside so it can be slid along a pipe
to somewhere that needs a repair. If you used a normal coupler to
mend the hole you'd have to cut the the pipe.

.... or even if you cut the pipe the slip coupler can be slid right
onto one side of the cut and then, when you have aligned the two
halves, slid over the join.

At least this is my understanding of what it's for.

That's about right. It enables two pipes to be joined end-to-end without
needing to move one of the pipes axially to fit the coupling.

Think of them as repair sleeves ....
If you use a normal coupler you have to be able to move one of the pipes
away enough to allow you to get couple in place, with repair coupler, you
lift one end of cut pipe ... slide couple right on (past pipe end) line
pipes back up and slide coupler back.

You missed the vital first step.
- Mark one of the pipes to indicate where the end of the coupler
should go.

and the final steps becomes
- slide coupler back so that the end lines up with the mark.

Or put a mark the same distance back from the end of each pipe, just
a bit further in than half the slip coupler. Then align the coupler
midway between them. Depending on how big the gap between the pipe
ends is, this may be a better way of getting the alignment correct.
At least the amount of pipe in each end should be equal. With the
single mark at proper depth, the other pipe will only be in the
proper depth minus all the gap.
