I'm having no luck finding a replacement. Any help identifying would be much appreciated! Thank you in advance!
Unless it's just a simple washer or packing material that needs replacement, finding replacement parts will not be easy. By the time these start to fail, the new ones have completely changed so parts are not interchangeable. You could try an old fashion hardware store, like the ones we had before Home Depot and Lowe's, or a plumbing supply store. If you can't find parts, you'll have to replace the whole thing. It's usually a pretty easy job if you can get to the inside wall where the silcock attaches to the pipe. I've replaced many in the midwest because replacement parts were just non existent.
