pipe size needed asap please folks

[timbo41]

If anyone had a budget Pressure barrel at hand, any chance of measuring or guesstimating the diameter of the tap spout ...I'm not near the cave at moment, ,but want to order some pipe or beerline to go from spout to a demand valve. Cheers all!

Budget PB barrels tend to be 1/2inch internal diameter although some are 3/8th just to confuse things. If you are talking about a demand valve for a beer engine then the one I have is 3/8th inch internal.
I find these invaluable when connecting different pipes:

They contain 3 short pieces of different size tubing that have a multitude of uses.

Cheers boss for quick answer. I reckon I'll order 1/2 inch. A bit of offer and a hoseclip will solve any slack. And that other little link is handy thankyou
