I currently have a pair of 47kg propane cylinders on an auto changer feeding a 6 ring gas hob in the kitchen. The pigtails are all brass, this type..

I'd like to switch to smaller 19kg cylinders and to do that need longer pig tails. Was thinking of switching to this type of pigtail which don't need a spanner..

Obviously that makes the cylinders easier to pinch but I can fit a padlock to prevent that.
I'd like to know if anyone has experience of these? It looks like they have a rubber seal rather than brass on brass. Are they prone to leaking or any other issues I should know about?

Never seen them before so the first question would be there certification and compliance.
More importantly is the gas bottle size v the cooker rating.
The smaller the bottles the lower the off-take so they may not be suitable for your appliances.
example 19 kg bottle in brks.
Kg/hr 2.46 (1.37)
Kw 34 (19)
ft³/hr 46.4 (25.9)
M³/hr 1.27 ( 0.71)
Btu's/hr 116008 ( 64828)
The above is maximum off-takes at 15°C as you can see considerably lower.

Thanks. The pigtails seem to meet same standards as the all brass type.
Hadn't thought about the reduced gas flow rate, will investigate.

Good catch. With all rings going flat out I make the total 20kW. Guess I best stick to the 47kg cylinders.
Think I will still go for longer hoses as it will be easier to connect the bottles. Currently it's very difficult as the hoses are a bit short and with the tall bottles I'm having to work in a confined space under the fixed lid of the cabinet.
