We've brought our gas cooker from Europe, and it has a regulator with a 21mm (1/2") female connector.

I've bought a 2kg gas bottle, but this a standard 3/8" (16mm) male connector. So that doesn't fit.

I've been searching on the web for a 16 to 21mm adaptor, but I can't seem to find it. I see a lot of references to POL connectors, but that doesn't seem to be it.

Where to find an adaptor with 3/8" female to 1/2" male?

That is some kind of European bottle connection. I'm interested to know what the proper name for that connection is.

Flatmate imported a caravan from Germany, and it had that thread. I hacked up that adaptor and brazed on a POL adaptor. So he can use 9kg bottles.

The 3/8 left hand thread on your 2kg bottle is called companion thread BTW. POL is the standard used on 45kg bottles. And 9kg bottles use a valve that accepts both POL and QCC.

Whats the size of the the other end of the hose (the part where it attaches to the cooker)

You might be able to find a new hose and regulator.

Are those euro regulators ok to use in NZ?

Adapters are not safe.

I think you might find that you need to get your cooker certified for use in NZ

Gas appliances must be safe when used with the gas for which they are intended. This is typically either natural gas, which must conform to NZS 5442, or LPG, which must conform to NZS 5435.

Plenty of gas places around that can help you get up and running. I would suggest you dont 'cheap out' and try and hack up a workaround.

POL is the standard fitting on gas bottle for BBQ's and Heaters Etc. usually 9Kg and up but see below for an exception.
"CGA 510 or POL Most widely used in this industry, POL is the common name for the standard CGA 510 connection. Thread specification is .885" – 14 NGO – LH – INT, meaning .885" diameter thread, 14 threads per inch"

SIEVERT/COMPANION is the standard fitting on camping stoves, lamps etc and smaller gas bottles normally less than 4kg, though 4kg bottles can have both types of fittings
pretty sure its 3/8th BSP.

If you replace the regulator - check it's outlet pressure. The German caravan had a 5kpa regulator. Which is not widely available in NZ. Most of the locally available regulators only output 2.8 or so kpa. And it avoided the can of worms that is operating the system at a different pressure to its design pressure.

Thanks all for your replies :)

The current regulator is 1.5KG/hour. On the hose it says it's 8mm. E.g. the one from Bunnings is also 1.5KG / hour and 8mm: https://www.bunnings.co.nz/campmaster-gas-regulator-3-8-lh-w-1000mm-hose-1-4-bsp-outlet_p00881483

The 2kg gas bottle I have is a Companion ( 3/8 BSP) fitting.

So that should work, right?

You need to check the outlet pressures. The bunnings one says it is 2.8kpa, What is your old one?

Post a photo of its rating sticker.

29 mbar = 2.9kpa so should all be good?

All good, just be careful with attaching the hose to the cooker, as there is a variety of different flare and flange style connectors.
