Just to be clear, I'm talking about combining these two parts:

Compression Wallplate Elbow 15mm x 1/2"

Hose Union Bib Tap with Double Check Valve 1/2" DZR

I was under the impression that if you install the elbow so that
supply pipe is coming straight down to it, the tap should screw all
the way into it & end up pointing down. (I'm pretty sure that's what
I did with the old ones, which were removed as part of a kitchen
renovation, so I've installed new ones in a different place outside.)

In practice, however, I installed two of these the same way but they
ended up pointing in slightly different directions, neither straight
down. I ended up packing a couple of fibre washers in each elbow
until I got the right direction. What am I missing?

Thanks.


Ptfe tape?

I tried it with and without PTFE tape on the threads. Both ways, the
tap went in farther than I expected, ending up pointing down and left
rather than just down.


I believe Jim meant make your own washer with ptfe, not wrap it around
the threads.


Near enough yes, wind on threads but multiple winds near to tap
end of thread, makes a custom PTFE washer in effect..
