These are leftover from a solar hot water installation. Mostly 1” thick walled red brass with some 1” to 3/4” adapters. Nipples of differing lengths, a “t” and a little of everything else as shown in the picture. 2 1” threaded unions. 1 threaded 1” gate valve. If you’re looking for something specific i might sell individually, email or chat me and I’ll let you know. UPDATE: the photos shows what I have left. please inquire if you have a specific need, thanks
