Honest enough question there Peter.
Tha answer is too right, provided they are made for gas and not water.
You probably can't mix them up any way as the gas ones will have a POL fitting in one end easily signifying it is for gas.
Ignore the angry negative responses, they are irrelevant.
Some people do not know how to be polite.
Cheers, Bruce.

thanks for the replies polite and rude I suspect the limit is 1M,,but surely a joiner is available,,and if the line was in a casing to protect from
debris and allowed a flow of air it would be safe,,i will
check out the rules and will report back during the week

Peter I've seen long than 1m lengths available at
BCF. Guy said it was so you could leave the bottle on the roof rack and still be able to reach most portable stove set-ups. Length I saw was 2m or more and no regulator. Was also told (true or false?) that a regulator is only required if the bottle is part of a fixed stove set-up like in a camper trailer or caravan.

sort of true - as long as it's not permanently connected and the gas source isn't in a confined space....

AS5601 part 2 is the gas code that your gasfitter would need to be familar with. The length of hose varies depending on where and how they are used. As a guide,
[2.11.1] Hoses shall be of a minimum practicable continuous length .
[2,11,2 ]Hose assemblies shall only be used between the regulator and rigid piping, and between rigid piping and appliance. For caravans connecting pipework between bottle and appliance that exceed 1m shall be made out of a combination of rigid pipe and if required ,flexilbe hose that is connected to the rigid pipe.
[5.2.5] Hose assemblies shall be- [a] of minimum practicable length not exceeding 1.5m - [b] used only between the regulator and rigid piping and between rigid piping and appliances, or where there is only one appliance, directly between regulator and appliance
[5.1.4.1] deals with the requirements of the high pressure piping between the bottle and regulator including hose assemblies.
This info has been provided as a guide only and yes all gasfitting work is covered under various state laws and only licensed gasfitters can work on any gas system so don,t muck around with it as it is not only you who can be impacted when things go wrong but also innocent bystanders .

rags has the best advice ....
check with a licensed gasfitter.
I remember asking a similar question of my local gas fitting supplier regarding flexible hose from my external gas bottle to my internal stove... this guy knew what he was talking about and launched into a detailed description of regulations regarding distance, high/low pressure, and external vs internal hose fittings .... in the end he looked at me rather exasperated and said, basically get a proper gas fitter to assess and do it !!! easier in thel ong run if you want to stay legal....

This should be a standard disclaimer added to every thread about gas.

I have been to the gaseous man,,,he tells me that rigid pipe encased in hose or similar is required to protect the gas line from damage where it runs external to the chassis
Flexible line is ok between appliances/bottle and the rigid gas line
In vic. you can do your own gas work on a van,,but it must be inspected by a gas fitter to have a certificate issued l

I have just fitted the third gas regulator to my camper trailer. It's a two stage one and has a flexible line from the bottle to the reg, and from the reg to the stove.
Thought after two failures, I would contact the regulator man to see if there was an issue with the mounting or type of unit being used. Shouldn't be failing that often.
Interesting response. They are saying that flexible lines to the gas regulator are being damaged by the gas. It is causing a black goop to form inside the regulator as a result of the rubber in the flexible line breaking down and this in turn is damaging the diaphragm in the regulator. In some cases in 6 months.
Recommendation is to avoid flexible lines from the gas bottle to the regulator. I have just fitted a copper line from each bottle through a line 1/line 2 switch into the regulator. Have formed a pigtail in both lines to the bottles to give some flexibility and to assist when removing bottle for refill.

My problem is the flexible gas line connected to the regulator. The regulator is remote from the bottle and is being damaged. BBQ's have the regulator directly screwed into the bottle so don't have the problem.

Can't do that and it wouldn't fit anyway.
Regulators and installations for trailers and caravans needs to comply with gas regulations for fixed appliances. Regulator is a two stage one mounted vertically so dust and water do not get into the vents.
