Gas pipe connections (1 Viewer)

[funman]

Can anyone help me here, I wonder? I have a refillable LPG bottle (Safefill brand) and the pigtail that fits it. At the end is a female connector which is 20 mm internal diameter, right handed thread. This would connect to a regulator to drop the pressure and thence to the gas stove, fridge, etc. I have a portable fridge and / or a Cadac barbie, which I want to run from this gas supply. How can I connect the pigtail to the Camping Gas regulator or another one I could buy, so I end up with a male push-fit outlet which I can connect to my fridge using standard rubber gas pipe? I don’t know the jargon name for the 20 mm connector, and all the regulators on the internet fail to show the inlet connection. The attached photo shows this 20 mm connector and the Camping Gas regulator input. If anyone knows who could supply either a 20 mm male to Camping Gas female connector, or a regulator with a male 20 mm input and a male rubber hose output, I would be immensely pleased! Put simply, I want to join the thing on the left of the photo to the thing on the right of the photo!

For connecting genuine portable appliances, ditch what you've got and buy a standard POL regulator (which the Safefill uses) and hose for each appliance. If you want to run both appliances at once, get a POL splitter which both regulators can attach to. If these appliances aren't actually portable, but fitted, the answer is different.

BTW, if you want to use the pigtail and run to fixed appliances, you'll need "bulkhead" regulator. However, these normally run to fixed copper pipework (i.e. 8mm/10mm) rather than portable hoses. I suggest you find a gas engineer to sort it out if this is the case, as there would be something fishy about running fixed appliances from hose.

Thanks for your help. The POL regulator shown on the eBay link looks like this (2nd pic) whereas to pigtail which came with the Safefill bottle looks like this (3rd pic), though both seem to have the same left handed thread. Would the POL one you suggest seal ok, do you think? There is a rubber seal in the bottle (1st

pic).

Also, I was wondering about the output pressure of the regulator. My portable fridge requires propane at 37 mbar or butane at 28, but it seems that LPG can be either! I would have got the gas years ago at an ordinary filling station somewhere in Western Europe, probably France or Germany or England. Hmm...

I don't recognise the first picture as a Safefill bottle. Safefill bottles are plastic (perhaps it is old and they used sell metal ones). I think this bottle might still be a POL based connection, but I suspect the rubber is actually part of the tail, not the bottle valve and has fallen off and needs to be fished out. POL connectors can either be brass or rubber at the end to make the seal. I'd favour connectors with a handwheel rather than nut, as you don't need a spanner.

Pressure wise, a regulator attached to your bottle will be 37mb. 28mb is for butane, which you don't have. A bulkhead regulator will be 30mb for both propane and butane. Most modern appliances will run off any of these pressures or gas. However, if an appliance is very old, it may be designed purely for 37mb and will struggle with 30mb. This isn't a problem for you, as you will be using 37mb anyway.

OK thanks. Sounds good. I'll have a go at fishing out the rubber ring shortly! By the way, the bottle is Safefill, it's plastic with a little window through which you can see how full it is.

Ah, the lighting made it look like steel!

The rubber ring appears to be glued in, rather than wedged in by mistake. I'll see how it goes as it is. Thanks again.

I bought a regulator as you suggested in the local motorhome shop £4.99 - works a treat. Lovely job.
