My little business, Blackfriars Ironworks http://www.blackfriarsironworks.com and on Etsy https://www.etsy.com/shop/BlackfriarsIronworks sells all the same pipe and fittings as you can get from your local hardware store but cleaned and electrostatically painted (won't rust) and for a lot less. We have ready made things and are happy to create a custom kits of parts for your project. Apologies if anyone is offended for this shameless plug.
