Are these rupture-proof pigtails?

I'm replacing my regulator with a Truma Duo crash sensor regulator. I think my existing pigtails are rupture-proof - is it possible to confirm by looking at the photo? Thanks.

No they are not, the rupture proof fitting has a red button to reset. However if those bottles are refillable then afaik they have internal protection that does the same job. You will need to check with the bottle supplier.

Answering my own question it seems that rupture-proof will have a green button on it, which mine don't have.

I assume since it's a gaslow system that it will require a UK, propane, pigtail as shown on this page https://www.caravanparts.co.uk/regul...4_365_366.html

Looking at the pics of my cylinders above, will these pigtails fit?

The Gas-It bottles I fitted this year have such an arrangement. I checked with the supplier who confirmed this. He stated that the feature is so good that if they get a new bottle that will not seal properly then just opening the valve fully will trigger the rupture protection & shut off the supply. Apparently if they need to empty a new bottle they have to open a little & then let the bottle empty slowly, takes around a week he said. When I replace my pigtails next I will be able to fit plain pigtails at around £10 each not rupture protected pigtails at £40 each.

It seems that my system is too old to have the rupture-proof technology incorporated in the cylinder.

So either I buy the CS regulator and CS pigtails (around £300 fitted) or I buy 2 new R67 cylinders which have integrated crash sensors (around £370 fitted) with the possibility of selling the old cylinders to offset the extra cost.

Seems a no-brainer to me, spending an extra £70 to get a more streamlined system and cylinders that will last another 10yrs or more.

What think you? Am I missing something?

Won't Gaslow exchange your old cylinders for the newer type for a lower cost?

The person who installed the originals said I'd have to sell them myself.

The trouble is there is a date stamp on the cylinders, by which time i suppose they have to be changed?

Just a thought, might help you decide. I have not seen CS pigtails in stainless only rubber which will need replacing every 5 years at £40 each. Truma do not sell the pigtail hose separate from the CS fitting, however you can separate the 2 items, left hand thread, and change from rubber to stainless. You could keep the existing bottles so that should you change vans you can keep the new ones. Not sure what the recommended life span of these bottles is.
