Title: Gas Cylinder fittings Post by CWatters on Jun 15th, 2018, 4:33pm 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.. https://gasproducts.co.uk/gas-regulators/pigtails/20-148-propane-gas-pigtail-pol-x-w20.html 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.. https://gasproducts.co.uk/gas-regulators/pigtails/gaslow-easy-fit-1-5m-propane-gas-hose.html 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? |
Title: Re: Gas Cylinder fittings Post by thescruff on Jun 16th, 2018, 12:52pm 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. |
Title: Re: Gas Cylinder fittings Post by CWatters on Jun 18th, 2018, 5:06pm Thanks. The pigtails seem to meet same standards as the all brass type. Hadn't thought about the reduced gas flow rate, will investigate. |
Title: Re: Gas Cylinder fittings Post by CWatters on Jun 19th, 2018, 12:27pm 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. |
