Need thru tank fittings!! for black water tanks

[ddpartybus]

I am looking for 3"-4" thru tank fittings. I made a waste tank out of a large cooler. The party bus runs year round and wanted to keep everything inside to prevent freezing. I need a fitting that will sandwich between the tank to create the seal and give me the dump that i need. I have found smaller sizes but i want at least 2 1/2"-3'

Check out Hayward flow control. Sorry can't find the website right now they will usually only talk to supplier's? BS but if you need them they are called bulkhead fitting's my company just bought some for a rain water harvesting system I am building. Depending on your area I have just learned that pool supplier's sell them but probably not in the bigger sizes. I have a supplier's name in my head but I don't want to give you the wrong info? I will send you another post after I find my shipping ticket. Sorry

Alright I found it in the stack of paper's in a 4 door truck that can only haul me and my filing cabinet??? The manufacturer for the bulkhead fitting's is Welcome to Flow Control and you need to know model numbers from there web site and then they will refer you to the closest supplier. Sorry I put the ticket in my hand's and remembered the BS but they have any size type and even swivel type but they are not as cheap as amazon but I can't find the size your looking for except for this place? Hope I helped?

The issue that my men have found with these fitting's is that you can't over tighten them!! So use plenty of good thread tape and pipe dope. Tighten them up by hand and use a wrench for one full turn. Sorry pipe fitter/welder by trade.
