I am thinking of replacing this drain assembly because of leaks at the strainer nut and slip nut fittings. Problem is I can't find a replacement for the curved pipe that attaches to the tub strainer. Can someone tell me what it is and if it is available?

Alternatively, I was thinking of replacing the whole trap assembly with PVC. Could I use an S-trap if it will fit?

If the copper fitting inside the wall is threaded, I would remove it, also remove the tail piece at the sink drain and screw in a brass nipple then make the connection with ABS or PVC Tubular piping. Reduce the pipe size to 1 1/4" with a 1 1/2" x 1 1/4" brass or plastic Nut under the sink.

It is a flanged 90 degree elbow. It is one half of a sink continuous waste, cut off to fit the situation. The other piece, turning down, is a 1 1/2" flush elbow from a toilet flush valve connection.

Makes no difference...repipe it for less problems in the future.

I don't believe the trap needs to be replaced.
as for the rest, there a couple of different ways of changing the parts.
have a look here at the parts and the video. it is all explained.

I suggested replacing the Brass Trap because tubular is inexpensive and has a smoother surface to prevent Lint from causing a stoppage. Improve as you replace...

sloren, you are gonna give our friend from SC (bernabeu) stomach acid.
actually, I think he has a good brass trap with a union nut to take apart and clean really well.
unscrewing it without a big enough wrench to use as a holdback could be troublesome.
I'd take it apart at the union , clean it and the outlet pipe and leave it.
in fact, he may only need a tailpiece washer, a couple of new nylon slip washers and some grease and be as good as new.

Thanks for all the advice everyone. The trap is brass and still in good shape, so I will start with Mr Packy's suggestion to take apart and clean really well. Then replace the washers hopefully will get a good seal.

Reducing it to 1 1/4", (and I am not sure how he could do it), as you suggested, would NOT "create problems in the future"?

I like going to plastic tubular because it is easy to cut to length, smooth as I said and you have more options. Durham fittings and Gal pipe or Brass requires more work with fewer options than plastic. The reduction to 1 1/4" is simply by using a 1 1/2" IPS x 1 1/4" Tube reducing slip nut. Easy Peasy....
