I am currently replumbing my 90 gal with new bulkheads which are 3/4inch and 1inch bulkheads going into a AGA megaflow kit. My question is are these Slipxslip bulheads? This is what they appear to be to me, I want them to only be threaded on the outside so I can slip the pipes into them. Also what is the best place online to get these parts and loc line as well? Do you actually need that special tool for the lockline or not? Thanks
