Sodestream bottle problems.

Sorry philip, just realised that you are one of our friends from down under..Please disregard last post! :uhoh:
But Rhys, remember its certified or its 50psi!

I found camping gas bottles with a 1/8 bsp tread on the neck. Those are safe up to 20 bar (290 psi)

Sodastream or paintball bottles are overkill, as they can take 2000psi+. These are to heavy for this purpose

Yeah, Im planning to stay firmly within the rules. The sodastream bottle has lots of stuff embossed onto the actual bottle, so Im guessing that means its certified? I noticed 250 bar max on there, so as Im only running them at 10bar (at the absolute most) Im assuming I wont have a problem getting through tech check with this?

just took one of my old soda stream bottles apart and it apears to have a 3/8th bsp male thread on it underneath the brass adaptor. Unless 18*1.5 metric is a very close compairison to 3/8th bsp. Im sure you could get a 3/8th female fitting from technobots and put it on to use the bottle as a buffer tank.

If you want the bottle its urse, no cost.

Rhys .....Did you get my email?

RE:-Pnuematic Air Tank 2.5 Diameter - 4 Long?

It should be perfect for you .......being a purpose made commercial item for this sort of application.

I didnt, but I have got it now. They look pretty cool. Ill defo have one of them if you win. Let me know the full price when you get them and Ill send the payment over. Cheers Woody.

Dave, Ill still have that bottle off you as well. let me know the price for postage and Ill get the cheque sent over.

A 3/8bsp is close to a M18*1.5 the 3/8 bsp is 16.6mm diamter outside, and the M18*1.5 does tell enough.
But close doesnt mean a sigar. The closer , direct metric tread-alike- to a 3/8bsp is the M16*1.5
