Help....need to adapt 1/2" to imported 15mm shower fixture

[Jim TAte]

I have a UK imported exposed shower valve that has two compression inlet pipes that only accepts 15mm pipe (after being wrongly told that it also accepted 1/2" by replacing 15mm ferrules with 1/2" ferrules).
Tile guy arrives in a week or so.
Anybody have a USA sourceable solution?

Getting desperate and thinking about having some heavy wall K-type 1/2" tubing down to 15mm O.D.
You have to take 0.625 OD (1/2" pipe) down to 0.590 (15mm)
With K pipe that leaves a wall thickness of 0.031 which is thicker than regular M type (0.028)

K, L, M tubing have the same outside diameter . I use L tubing fro all above ground hot water heating and potable water systems and K for under ground

Try contacting a faucet repair parts place NY replacement parts in Manhattan they usually have the correct adapters or LAS replacement parts also in NYC

"K, L, M tubing have the same outside diameter ."

I understand that they are all 0.625" Outside Diameter for standard US 1/2 nominal copper tubing.
That 0.625" equals 15.87mm

The UK valve has a ferrule for european 15mm OD pipe (0.590")

One idea I floated is that at the stub out of the 0.625" OD pipe I would lathe down the exposed portion down to 15mm/0.590" so that it fits into the Euro valve

The thick wall K pipe has an Inner Diameter of 0.527 which means that I have a resultant wall thickness of ~ 0.31" which is marginally thicker than the wall thickness of thinwall type M so I think that is OK for thickness.

If I tried to lathe down type L or M the resultant wall thickness would be too thin or non existent.

I found your referrals on web. Will give them a call tomorrow.

I wonder if going from 0.625" to 0.590 can just be done by chucking pipe into drill press and sanding it down?
Don't necessarily have an easy solution to chuck a 0.625: pipe into a 1/2" chuck though.
