2 tank hook up, for connecting two tanks together and draining them at the same time. 30" POL Male x POL Male Hose. Propane Tee block is POL Female x POL Female x POL Male. If you need to connect 3 tanks together you would need two of these kits. 4 tanks together you would need 3 kits.
I wanted to connect (2) 30lb RV tanks together (in parallel). Sounds easy, right? WRONG!!! I searched everywhere on Long Island NY for something and came up dry. Well, I did a Google search and this site save my tail! I bought one of these kits, hooked it up to my 2 tanks in less than 5mins and VOILA -success! Simple, effective and works great!!!
