They don't have 1" LocLine. I reduced to 3/4" and used the wye to add 2 flair nozzles. If you're looking to buy locally although not my first pick for a LFS Pacific Aquariums has it in stock now. They may not know what you are asking for but it's behind the counter and if they don't have the threaded reducer there it's in the back storage section in the parts bin.
