Threading copper pipe: There's gotta be somebody that has...

[NickGold123]

So I've built a few copper pipe mods, one with a switch and one with a spring compression connection. I'm determined to build a threaded design (like most other tube mods) that is a straight tube all the way with threaded screw on caps that line up flush with the tube. (Not over top the tube, like an end cap fitting)
Who knows what taps and dies to use?

First off don't try threading the standard copper pipe used for water lines. It can be done but you risk cracking the pipe and the threads strip very easily. One way to do this with common water line pipe is to use a swaging tool to flare out the ends and solder in a threaded collar. OTherwise get some 4-6mm wall copper tubing and you can thread that with out issues.

Edit: Use a tap that matches the inside diameter and at least 28 pitch. I.E. 3/4 ID needs a 3/4x 28 tap.

Finally a straight answer. THANK YOU.
I've been reading up a lot on this and all I've found was "You shouldn't because..."
Wall tubing was my next step since there's thicker wall options. Plumbing pipe can only do so much. Lol

YW. I do a LOT of plumbing work as part of my business and you would be surprised at how many customers ask me why I'm not threading the pipe for proper fittings. Most taps in 5/16 or bigger, unless you get custom made ones, have 3/32 thread depth and considering copper pipe has at most a 1/8 wall thickness you can see why it cracks. McCaster & Carr or Granger are good places for specialty tubing sizes.

Sweet. Thanks again

Would refrigeration grade hard copper work better?
