I'm looking for a couple of 2"x2" copper pipe couplers, e.g.,
Mission K200 or Fernco 3003-22. None of the usual online supply
places seem to list them, and the number of Google hits for the
Fernco version is oddly tiny. (The big box stores of course don't
have those sizes and the local plumbing supply place has gone
trades-only.) For 1.5" copper I think everyone just uses the 1.25"
plastic/CI versions which are readily available. Is there a similar
trick I'm missing in some other series that is more available? Or
an online site with the real copper-coper versions--I like the
shielded ones better anyway.
