I have a Westfalia interior, but the hob/fridge doesn't have any gas fittings installed.
All that is there is a short pipe with a thread at the end, one for the hob, and the same for the fridge (see picture, apologies about the quality of it)
It looks like you should be able to just fit a pipe with an olive and nut, but not sure of the thread size due to the age of the appliances. Does anybody know what size thread this is? and what fittings I would need to attach to it?
I've taken mine off many times but apart from saying 'Metric' cus it's German, I really don't know.
You could drive the van to your local plumbers suppliers and I'm sure they wouldn't mind you trying a couple of unions.
Note* as a side note.......Westy regulators run at 50mbar so any british spec hob would need to jetted accordingly or further regulated down to 28/37mbar?
Thanks for the info. does that mean I'd need a 50mbar regulator for the original Westy hob? The regulator I'm using at the moment (not sure of manufacturer of the hob) I think is 28mbar.
I've measured the pipes using a micrometer, the one from the hob is 8mm steel, and from the fridge is 10mm copper.
E D I T: I just tried the nut from a 12mm compression fitting, and this fits fine, so indeed it is a metric thread
Now I just need to find a couple of unions the right size ... somehow

I know...nothings ever as straight forward as you want it to be.
Have you still got your Westy underslung tank? if so, has it still got it's original 50mbar regulator?
Or..are you using a seperate butane/propan bottle?
Obviously the original hob needs a 50mbar gas pressure feed.
My Westy doesn't have the original "kitchen unit", but I've recently acquired one, but without any gas fittings installed whatsoever (no under-tank either, was hoping to use a little 907 inside somewhere), so will need to somehow source a 50mbar regulator too lol
The kitchen unit in the camper at the moment (with completely different hob) is running from a 907 bottle with 28ish mbar regulator
E D I T: There's plenty of 50mbar propane regulators around... I'm wondering if a clever person has invented an adaptor to allow it to fit onto a butane cylinder (wishful thinking lol)
Go on BES.com (plumbing site) find the 8mm stainless steel fittings, these fit the Westy stuff. This is what I did anyway. Buy, say a 8mm coupler. That will get you two nut and olives that are the right size and shape.
If so, I've tried a 8mm nut onto the thread, which was too small, but a 12mm compression nut fits. But due to the shape of the fitting, an olive and nut won't screw on
(at the top is the output from hob, and bottom is the pipe coming out of fridge)
Or I could possibly cut off the silly threads, and fit a 8mm compression straight coupler to the hob pipe (assuming compression will work with steel pipe), and a 10mm to the fridge pipe
Ok, that first picture is of a union fitting, nut and olive wont fit in there. you need the the other part to that fitting. Gunzle might be able to help if you send him a email http://www.vwbusshop.de/epages/GuenzlCl ... ID=1209209" onclick="window.open(this.href);return false;
in the gas section you will see the same fittings i've linked above, they will fit the gas tank, and all the other compression joints, just not that union fitting

Although you are correct there martin, ive been running my UK spec hob with the westy regulator. Doesn't really make much difference, perfect blue flame. The gunzle place do sell a UK spec regulator that you can swap over instead of running two regs if you so desire
As both the pipes are metric (8mm steel from hob, and 10mm copper from fridge), wouldn't it be possible to chop off the union connector and just fit a standard compression coupling?
in short, yes. but steel fittings for steel pipe, copper pipe you can use brass or steel
Also if you put a wanted ad up, someone might be able to supply you with all the internal pipes preloved

Quoting richlaz....does that mean I'd need a 50mbar regulator for the original Westy hob? The regulator I'm using at the moment (not sure of manufacturer of the hob) I think is 28mbar.
Hob is unknown...if British then his 28mbar regulator is fine, if Westfalia then the pressure won't be adequate for a good flame.....applies to the Westy fridge as well, which is likely to keep going out as the flame may not be hot enough to overcome the thermo coupling.
The hob I'm running at the moment is identical to the Semv 927 (not sure if it actually is a Smev, or a lookalike, can't see any branding/logo's anywhere), and an Electrolux RM122 fridge. Both seem to work fine simultaneously (fridge does blow out sometimes if you slam the sliding door too hard, but I think that's inevitable).
Although the Westy fridge is slightly bigger (and more complicated!) than the RM122, so may need more pressure to run it together with the Westy hob
All depends on the jetting......if the RM122 is jetted for the regulated pressure.
What I'm getting at here is....if jetted for 50mbar of pressure the jet size will be smaller, connecting a 28mbar gas souce will result in a small flame. This could result in several problems: Tendancy for the flame to go out/there not being enough heat to overcome the thermo coupling/poor fridge performance.
Chances are the hob & fridge are correct for the pressure...I'm just pointing out possibilities....things you need to be aware of.
