PVC adaptors that fit 2 liter soda bottles?

Well, now you've got me thinkin! What interesting creation are you trying to make?

Since a pop bottle is a straight thread, i'm wondering if a garden hose connector or maybe a fitting to connect the water to a toilet fill valve? maybe if you took the bottle cap it would fit inside a standard glue on fitting and you could glue it in and then drill out the center. I guess now I'll have to go out to the garage and find out.

Not 100% positive but they should be the same as a garden hose thread (GHT) which is 3/4 x 11 1/2 tpi. Best way to check is take the top off a bottle and screw it to a hose and see how they fit. We actually make a drain that uses a garden hose thread and a 2 liter plastic bottle cap fits it nicely.

2 Liter Bottle Connector

Even though plastic is super cheap to manufacture, probably just to save money. I remember those. It was sort of like a cup to set the bottle in. Isn't it funny how a 2 liter costs around a $1.20 and so does a single serving of soda (20 ounce). Less plastic, same price.

well there in itself lies a problem. threads on a 2 liter bottle are not ips nominal threads. a 3/4 pvs ftg is too small and barely will fit. a 1in pvc fitting is just way to big. you will need to make alterations of some sort if you intend to use nominal ips threaded fittings. best luck

Do a search for the MegaBOOM STS. SportsmansGuide sells them and are currently on sale 3/18/2015 for $20. Your question came up in my search for something even cheaper to make 15 to 20 units.

I have been looking for the same thing and have even considering having them made but the cost is prohibitive. Wonder if there is a market besides you and me?

Make your OWN very simple ( I would drill AFTER fusing cars together)
