You can get male 1/2" bps to compression adaptors that also have a

Alternatively you could use a taper fitting and PTFE if you preferred.

Or even a parallel one with lots of PTFE:-)

Yup, it will work, but never feels as solid as a taper fitting.

In my neck of the woods there are plans afoot to switch over to ¼" high
pressure pipes. Makes a good deal of sense, but I suspect adoption will
be a very slow process.
