Anyone familiar with plastic welding/soldering?

IDEngineer:
On a lark I did a quick search and Amazon seems packed with all sorts of options. I'm not an Amazon guy (I normally prefer dealing with industrial suppliers) but this just doesn't seem that difficult.

For example, $19 gets you this:

https://www.amazon.com/Adapter-Connector-Replacement-Courtyard-Irrigation/dp/B095P6LXSR

...which claims to attach directly to your IBC Tote and even includes a brass valve.

If you don't need the valve, $12 will get you two of these:

https://www.amazon.com/Fittings-Connector-Fitting-Adapter-Connection/dp/B095JJKRKP

...which again claim to connect to an IBC 275/330 Tote and have 3/4 male output threads.

If neither of those does what you want, there are cross-referenced links on those pages to dozens of related products including hose barb outputs, GHT (garden hose thread), NPT, etc. Basically use these links as a starting point and you should be able to find almost anything you want.

Good luck, report back!

I don't really trust Amazon for something that will be used for potable water, but most of those probably won't fit anyway.  The Camlock one I got from Global Industrial fits but the 2" to hose adapter won't fit on the camlock, the 2" threads  are not quite the same.    I can't find one that uses NPT threads only NPS, I think the threads on the camlock are NPT.   The problem with buying stuff like this online is it's a gamble, as the sites are not always descriptive enough or the pictures are not even of what you're actually buying.   I THINK this might fit but not 100% sure.  https://www.grainger.ca/en/product/REDUCER-BUSHING%2C2-X-3-4IN%2CMPTXFPT%2CP/p/WWG6MV71?

The ones on Grainger MIGHT work, but it's hard to tell from description if the 2" side is male or female.  It says male but not sure if that means it mates to male or if it is male. 

I can keep ordering stuff until the cows come home but it will get expensive.  I'm at a point where I just need to cut my losses and fabricate something.
PaulAm:
If it is a reducing bushing, the large size is male and the smaller size is female.  That's what a reducing bushing is, full stop.  Also, the picture in your link shows it clearly.

NPT threads are tapered, NPS are straight so NPT threads are normally used in a pressure situation as the interference fit seals better.  Still, they will leak unless a sealant is used.  NPS absolutely will leak without additional sealing methods.

If you make something you will probably pay more for the pipe tap than you would for the bushing.  Unless you cut them with a lathe with a taper attachment (or CNC).

Really, this is not that complicated.

Steel, galvanized or PVC usually are not a problem with potable water.  Brass may or may not be allowed depending on the composition.  Grainger, at least, will tell you if brass components are legal for potable water systems.  Don't use any cheap no-name brass fittings in potable systems.
rdl:
Any attempt to "weld" dissimilar plastics seems almost guaranteed to end in failure.

I did a quick search for "IBC tank cap with outlet" and found just about every variety I could imagine. Maybe that will help.
IDEngineer:
Agreed on the NPS threads. They are NOT a sealing connection, always used with an o-ring or other sealing element. Don't rely on thread sealant either. History is littered with failures like that.

You can use something like 3M 5200 adhesive but it will be a permanent connection. Emphasis on permanent. And even then I wouldn't rely on NPS threads.

Fittings are everywhere. Heck, I'd never heard of these water containers before this thread and part of my actual job is managing water through pipes, hoses, and fittings in all sorts of materials. Trust me, what you want is already made by someone and they've already figured out how to do it properly. A few minutes of searching should reveal tons of options.
