Must agree with the others Andy, proper clips should be used, cable ties can deteriorate or get damaged, I have even know them to come undone.

They don't actually need any type of clamp on them for 30mbar. The barbed connectors are just designed to be used without clamps. The cable ties are actually unnecessary so if they fail it doesn't matter.

Absolutely
Remember the chemistry lab at school and you just got any old bunson burner out the cupboard and wapped it on barbed desktop gas tap
I don't recollect screwdrivers and jubilee clips and cable ties wernt yet invented :whistle:

really ?

that's a new one on me .. where did you get that info from ?


The dangers of LPG
Firstly it is corrosive and it is a "seeking" gas, which means that it is always looking for the easiest way out of its container, be that a cylinder or pipework, or appliance, and it will take advantage of any weakness in the system.

For this reason no soldered joints are allowed, unles they are "Hard Soldered" which is beyond the scope of all but the commercial engineers as it has to be done at 415°C.

So, for practical use, only compression fittings using Soft Copper Olives or "Cutting Rings" can be used on the fixed pipework and the complete system must be leak and pressure tested, requiring specialist test equipment and calibrated gauges.

Low Pressure and High Pressure hoses
As far as the flexible connecting hoses are concerned, either the Low Pressure (from the cylinder mounted regulator system), or the High Pressure (from the cylinder to the regulator on bulkhead mounted systems) there are two types of hose, obviously, Low Pressure and High Pressure.

It is not permitted to substitute a Low Pressure hose in place of a High Pressure hose, but a High Presure Hose can replace a Low Pressure Hose.

Fittings are different for the two types of installation:

For Low Pressure (after the cylinder mounted regulator) the hose must be fully pushed onto the spigot of the regulator and the spigot of the rigid pipework supplying the van, and MUST be secured at each end with either metal 'O' Clips or with Stainless Steel Gas Hose Worm Drive Cilps.

The Gas Hose Worm Drive Clips differ from standard Jubilee Clips in as much as they have a smooth inner surface which does not allow the worm drive to bite into the hose.

These clips should olnly be tightened enough to prevent gas escaping, and not too tight to crush the hose or cause damage by being too tight.

Hig Pressure hoses(from cylinder to bulkhead regulator) MUST have swaged ferrules seecuring the hose to the M20 Nut at one end and the Propane or Butane fitting at the other. No other type of securing is allowed.

Right, keeping this in context, we are talking here about a hose to an appliance (stove or bbq) outside the van, nothing to do with the hose supplying the van from the gas bottle or anywhere else inside the van. The whole purpose of the design of that type of connection is to make a seal between the ridges of the connector and the rubber hose, better than a smooth connection would. The clamp provides mechanical strength i.e. it prevents it being pulled off. 30mbar is less than half the pressure inside an inflated balloon and therefore it is not going to force the hose off the connection. 30mbars is of course only the pressure inside the pipe when the gas is turned off at the appliance. As soon as you switch on the gas at the cooker or bbq the pressure drops. So my point is that in this particular context it is not necessary to have clamps on the pipe.

The spigot only seals properly when a proper clip is used. If you don't believe this, try a soapy water test on one with no clamp..
Without a proper clip or 'O' clamp, Gas could escape and ignite.... or if someone tripped over it.. the hose could be pulled off.

I'm not going to debate further.. If you want to take risks.. fine.. but don't advocate to others that it's a safe method..or an acceptable practice, it's not.. there are sound reasons for using mechanical means to secure the hose to the spigot.

Why take risks for the sake of a two bob clamp?


Flexible Hoses
Use only marked and certified hoses BS3212 or BSEN1763 and which bear the year and name of the manufacturer and clips as LPG attacks and erodes natural rubber. Keep hose lengths as short as possible and less than 2 meters in length. All flexible hoses must be secured with proper hose clips. Make sure that the hoses are kept clear of ‘hot spots’ and inspect them from time to time.
Replace any hose that shows signs of wear or damage.

Mum doesnt eat BBQ she calls it junk food haha
Maybe it's because when the gang are lining up to be served at the bbq the line isn't dancing \ clapping in time with her!:giggle: Now how can I factor "ceilidh" into the equation?:unsure:
Or is there a more fundamental reason (looking back at my previous post).:whistle:

I have hundreds of free cable ties anyone is welcome to try pull mine off anytime :ROFLMAO:

for someone who is so particular about following good electrical practice and to the IEE regulations, which I applaud you for , I find it strange that you show a cavalier attitude toward LPG safety.. .. both kill.. and often when they come into contact with each other..

Gas safety is just as important.

Im my opinion it is safe, it's not tucked away out of sight but a short length used under my nose outdoors and inspected every use. I have no objection to anyone using clips anymore than wearing lycra :LOL:

@Jim editing is cut to 3 mins?

I promise you will snap the hose before they will pull off

I have to say ever since i put my roof torch down on the hose one time and made the smallest of holes i was surprised how big the flames were :rolleyes:. For peace of mind i would sooner use a jubilee clip at the unions. My concern would be , being able to pull them tight enough clamp the rubber hose on but i still might throw some soapy water on my hose.:LOL:

Wish my water works had that pressure, I'm stood there for ages in the mornings now. Looking forward to my prostate test.

Worm drive clips (Jubillee) are more likely to cause a leak than cable ties. They cause the hose to become misshapen by the clip drive assembly on small hoses. The clip or tie isn't there to seal the connection (the correct match of hose to barbs does that) but to prevent the hose being accidentally pulled off.

I use these where it matters (on gas welding hoses in my case). They're neat & easy to fit / remove and don't have sharp edges:

When I have removed a cable tie to fit a new hose or even to cut a few inches off and re terminate, I have always had to remove the section of hose on the fitting with a utility blade. The rubber sticks on brass like shit to a blanket.
This fitted 4yrs ago, if a tie falls off it is immediately noticeable but still does not leak

Guess this will be long gone?
I'm looking for a couple of these and have come across this on e-bay
https://www.ebay.co.uk/p/4pcs-8mm-G...-Motorhome-BBQ-UK/3011638811?iid=292376297910
however are they any good given the price?
Would appear to be "steel"(?) rather than brass.
Anybody use these or better sticking with these

Can't say I think that those bic-ties are a good idea ? :(Proper metal clips are the way to go.(y)
It's 30 odd millibar......a fart has more push behind it.
I didn't bother with any clips as all the hose stubs are barbed and the nut to the cadac valve block was finger tight and checked...no leaks anywhere.

I would like to buy the water version of this plug as we have the socket installed on the van but it was not available when we bought the van S/H. Handy to draw off water outside to save getting in van or washing sand off feet etc
The outside shower is well handy ive used mine a fair bit

Correct John. People go all weak at the knees because the hose says high pressure on it :LOL: :sleep:

I have used in the past a hose pushed onto an 10mm section of copper tube with no leakage detected. Anything below 7psi BTW is not regarded as a pressure unit, for the purposes of Statutory examination. It is however NOT advised, but then most modern "precautions" are based on "overkill" in order to avoid being sued!. Just about every "instruction" manual contains a long list of "Do Not", 99% of which is just common sense, something sadly lacking in the modern "snowflake" world.
