Brass joiner with what ever olive comes with it
Hi I'm new here, I am converting a exLWB crafter into a motorhome.
I am doing the gas at the moment, I am pretty competent and will have it all checked and pressure tested at the end.
It is a fairly simple set up,
-gas bottles at the back, 8mm pipe running the length of the van to a 2way manifold
-One outlet to a spinflo triplex cooker, one to a Dometic fridge.
I obviously need 2 straight couplers to connect my appliances to my copper pipes but the inlet pipes on the cooker and fridge
Seem to be stainless steel??
My question is do you use steel compression coupler and olives or a copper one.
Will a copper coupler bond to the steel pipe, and visa-versa.
Or can you use a steel coupler with a copper olive on the copper pipe side??
No one seems to mention this being an issue, they just say- connect the appliance....
Any help appreciated
Thanks for answer, do you use brass on your copper to copper connections too, or just final one to the appliance.
Also, am I right that the inlet pipes are steel on these appliances it certainty looks like it
Maybe a daft question but do you have the appliances yet? Only ask as mine came with the male, female connector parts and olives / bite-rings.
The only connector I needed to get for an appliance was for the gas hob as it was a domestic half inch bsp so I needed to step it down to 8mm.
Edit. Also, don't forget to fit a pressure test point. Arguably not essential, but for the couple of quid it costs it makes life easier later on.

don't know if it's steel seems to be, but as Witzend says, use whatever olive comes with the joint. i get my 8mm connections from Screwfix and they have brass olives, so that's what i use. i have a feeling you may be worrying about different metals reacting with each other. never known it happen in gas piping in vans
Hi as a gas safe engineer I can confirm there is a BS for the fittings that can be used. I will check on the BS tomorrow in work.
The fittings must have soft copper parallel olives the type found in WADE brass fittings. They are more expensive than your Screwfix fittings. They are available from BES online.
You use the same fitting to connect the bundy tube on appliances.
Hope this helps
I will defo put in a test point, thanks.
Still deciding on whether to get a bulkhead regulator with a built in test point and pigtails or stick with the old way of rubber hose/regulator as I have
A few of them already for various countries.
In which case I'll put a test point in where I convert to the copper
I was mainly just thrown buy the appliances having no connectors and steel pipes as I thought any connectors needed to be of harder
Alloy than the pipes to compress them properly, so I thought that connector would have to be steel. But was concerned that it might not
Seal to the copper pipe properly
They do sell steel 8mm connectors at leisureshopdirect.
