Putting my bootles back into van, I notice that one of the pipe connections has a washer whereas the connection on the other bottle does't and by design can't take a washer. Is this correct?

Hi Janet,
Tell us a bit more about your system - what gas bottles are they, are they identical? is it a system with a single regulator on the bulkhead or do you have separate regulators for each bottle?

Thanks Mike
Calor bottles, one butane, one propane. It is the butane that does not have a position for a washer unlike the propane connector which has a washer. The system is one regulator on the bulkhead
Janet
Thanks Mike
Calor bottles, one Propane with a connection that has place for a washer and a Butane with a connection that has no place for a washer. The system has a regulator on the .bulkhead

Hello Janet,
You tell us that the regulator is fixed to the bulk head. This means you have to use short lengths of high pressure pipe (pig tails) to connect the gas bottle.
You probably already realise that butane and propane bottles have different types of connector, so you cannot simply finish a butane and then connect a propane without changing the Pig Tail.
As for the provision of washers or not, different makes of connectors may use washes or 'O' ring seals but without seeing the actual units it is dangerous for anyone to make any assumptions and recommendations.
The safest thing to do is to have a competent gas fitter check the system and to advise if you need washers or not.

Hi Janet,
I'm sorry I can't help you with Calor Butane - I have pigtails for Calor propane, Camping Gaz butane and BP Gaslight propane. I would be surprised if there wasn't a washer but I don't know.
You may yet get a definitive response from somebody on this forum - the post has not been here long. Failing that, you could just take the pigtail to you local caravan dealer and compare it to the one they would supply for the same bottle.
If you are not absolutely satisfied that you have the right answer after that then I echo John's advice that it is worth checking with a competent person.

Hi Janet,
I think you will find that the 4.5 and 6 kg propane (RED) hoses will not have an rubber washers. A seal is made by metal to metal contact. The pigtail will have a male left hand thread.
On the equivalent Butane (blue) the pigtail has a Right hand female thread with a rubber sealing washer.
I think this is right but if not I am sure someone will shoot me down !

Hi James,
I thought that Janet was talking about the other end of the pigails (where they connect to the bulkhead regulator) as she remarked that the calor propane connector was the one that had the washer and I knew that the bottle end connection is the reverse thread metal to metal.
It goes to show that making assumptions is dangerous, I should have asked Janet which end of the pigtails she had the washer.

Hi Mike,
Thats why I waited so long before replying, I wondered why someone hadn't answered Janet. I didnt think of the other end either !!
Cheers Jim
Hello Janet,
as you can see there is debate about what the situation is, so I reiterate my advice which is to seek the assistance of a gas competent fitter, who can actually see the relevant fittings.
There have been other comments to your question, and in two specific areas they are wrong.
Firstly any washer if required will not be rubber, because LPG butan or propane will actually dissolve rubber. any washer or flexible parts will usually be manufactured from nitrile based material.
Secondly and relation to the propane 'POL' type connector some connectors incorporate a non-return valve. Some forms of this incorporate an 'O'ring seal.
For your safety do not assume the answers on this topic are correct - have it checked out by a fitter who can physically see the fittings.
