John, I don=E2=80=99t recall having trouble with old tubing/pipe = & new fittings.

I just looked up the O.D. of =C2=BE=E2=80=9D pipe & tubing for = water & it shows to be 1/8=E2=80=9D larger than what the pipe is = called, so that would be 0.825=E2=80=9D.

There is another system of copper tubing intended for A/C use. The = diameters for this tubing is the same as the call size, so 7/8=E2=80=9D = tubing would measure 0.875=E2=80=9D.

I don=E2=80=99t have access to detailed metric charts but it seems = that the call size in MM is the same as the external diameter. = 0.9=E2=80=9D is just under 23MM, but I don=E2=80=99t see that there is = an actual 23MM tubing on the market.

If it is possible that the pipe was full of water & froze, the = pipe could have expanded that 0.025=E2=80=9D I=E2=80=99ve had that = happen when I was in Denver decades ago.

I don=E2=80=99t know what you have, but with only about = 0.025=E2=80=9D that the fitting would need to be stretched, you might be = able to do that with a swaging tool, or make something that will do the = job.

You might want to check with an old plumber to see what he/she = knows.

Are there any markings or brand on the cap you cut = off?

Where are you located?

Good luck.

Peace,

Pat

When we built = my house/shop 25 years ago I had the plumber install a 3/4=E2=80=9D = water line to the shop and cap it off.  I was going to put in the = sink and the outside faucet when I got time.  Well,  this week = I got time

I cut the cap = off and test fitted a 3/4=E2=80=9D Tee to start dry fitting the plumbing = for sink/faucet.  The Tee wouldn=E2=80=99t fit on the tubing.  = I cleaned it well but the Tee was still too small to fit over the = tubing.  It looks like he used coiled tubing, or at least = that=E2=80=99s what=E2=80=99s coming up thru the concrete.  I tried = several fittings and even cut the tubing lower to see if it was crimped = or out of round...  it mic=E2=80=99d the same all the way around it = in several places

I mic=E2=80=99d = the tubing and the fitting and here=E2=80=99s the = results

tubing i.d. = is  .882=E2=80=9D which is just over = 7/8=E2=80=9D

tubing o.d. = is  .900=E2=80=9D  which is just under = 29/32=E2=80=9D

a new standard = Tee i.d.is .876=E2=80=9D   which ain=E2=80=99t gonna fit over = .900

if I can find = one fitting to get this to standard 3/4=E2=80=9D size I=E2=80=99m good = to go...

did the old = stuff differ from todays standard = =E2=80=9C

after = researching fittings a little I see that there are several = =E2=80=98types=E2=80=9D of fittings.... from plumbing to hvac to = whatever...

anyone wanna = try and give me some guidance here... the net is confusing and offers = little on actual dimensions

thanks<= /o:p>
