I'm replacing the p trap behind a pedestal sink. Where the drain enters the wall there is a bronze or brass 90 degree elbow with 1 3/8" ID. I found a length of 1 3/8 OD copper pipe. How do I go from the 1 3/8 copper pipe to 1 1/4" P trap? A simple reducer? The rubber connector with 2 gear clamps?
FWIW it looks like previously the 1 1/4 was stuffed into the 1 3/8 - chrome p trap so it couldn't have been soldered.
Option 1 - trap adapter connector. This is a trap adapter. The side with the nut and gasket slides over your copper trap arm, the other glues into your ptrap. It needs a short length of 1-1/4 abs to couple to the ptrap as both the ptrap and trap adapter are female (you could get lucky and find a male style at a local Emco or Wolsley hi plumbing supply). Take your copper stub out to the store to test fit as there may be slight variations in the compression ring by manufacturer.
Option 2. This is a bit ugly, but it’s common. The connected is a 1/1-4 Fernco, and in one side, copper in the other abs. Simple gear clamp, it’s code compliant.

Thanks. Option one doesn't work since I'm running chromed brass trap and drain. #2 could work but again ugly and very visible. Plumber where I picked up the copper pipe said he would just sand off the chrome and sweat them together, which is what I was thinking of doing anyway.
Of course now we go another day w/o the a bathroom sink because I can't get a deep 1 1/4" escutheon plate to cover this in town. Headed to London tomorrow any way but.....

Ok, that’s a different setup. Brass(chromed) traps come with a trap arm that goes directly to the drain connection in the wall. Not easy, but you can use a belt sander to sander to remove chrome on the ptrap arm then sweat it in.
If you have room, solder with everything hooked up. Brass has no give, so even a slight alignment of the trap arm will make assembly tough.
Keep a fire extinguisher handy for that procedure. When I’m sweating in tight flammable spots, I pack the area loosely with tin foil to block flames and dissipate heat.
