For sale is a lot of about 13-14 lbs of used copper pipes, 3/4 diameter mostly and some 1/2 etc. What you see is precisely what you get. One short 2" long fully threaded pipe nipple had thread damage due to my mistake. All others are fine. When I say copper, they could be coppper or brass, but no ferrous or aluminum etc items are included in this lot. The rubber gaskets are for use with the flanged ends (all solid copper alloy). These come from a military helicopter test set.
