Extending a compression t with a slip coupler

[hardya]

It has been suggested that where I have imoveable piping and I am fitting a compression t, in order to get the right fit I could cut a wider gap and include a slip coupler.

The terminology may be variable (coupler, coupling, joint) but from what I can see of a slip coupler it appears to have no stop, so I guess that will help me get it out of the way to fit the compression tee.

However, given the pictures I have seen of a "slip coupler" I would end up with the identical fitting on the compression tee meeting the identical fitting on the slip coupler. Ought I to be getting a type of slip coupler with a partciular fitting at one end? How do I accurately describe that fitting in order to explain what I want?

Some pictures I have seen described as slip couplers have no threads on either end and so although one end may fit into my compression t, I am not sure how the other end will attach to the pipe

Does this make sense or am I thinking of the wrong parts? ??????

Makes sense to me. How much pipe can you remove to fit the conpression tee

You will have cut out the pipe. Fit the compression tee onto the cut pipe, then a small bit of pipe into the tee with your slip coupling, slide up the coupling and solder, then tighten tee.
