Newbie Question - 1/2" female adapter onto 15mm compression

[crispy_wafer]

Have to admit I'm learning slowly with what can and cannot be done, but last night I was playing with 15mm brass wallplate, and a 1/2" - 15mm hep20 female socket.  I found I could take the nut and olive away from the wall plate and thread the hep20 female socket on to it. 

 

Can I do this, or am I likely to cause problems for myself at a later date?

 

Thx

I'll give my reply and let the proper plumbers come in a minute to agree or disagree.

 

It will work, BUT it is not right.  The fitting your HEP adaptor is intended to connect to looks almost the same, but the edge of threaded pipe it fits to has a pretty square edge.  Your fitting intended for a copper pipe with an olive has the end machined out to match the olive so presents just a very thin edge of pipe.

Thankyou, I wont entertain that idea then, I've got 1/2 f to 1/2 f wall plate adapters that I'll continue to use.

Or a short piece of copper pipe from the olive conn then hep20 !
