To make the pigtail, you will need a leak-proof hose. Chose to use a long double-bard union hose. This will now allow you to connect the two different kinds of tanks or gas cylinder bottles. Then, cut the pigtail in half and join the NA POL (the hose segment with covered POL fitting in).
NOTE: You need to follow the provided step by step instructions for doing a tank-to-tank refill, following all safety precautions, as this is known to be an illegal refuelling method. This is a slow and somewhat inefficient process.
My choice was to join the other half of that pigtail you cut in half (the one with the invented POL fitting at the end) to the same regulator fitting + hose, and you will be able to have a gas-tight connection between a gas cylinder and your regulator. Go ahead and use your custom tank-to-tank pigtail. The one connecting your gas cylinder valve to the POL installed regulator.
When you build a custom pigtail (self-made), make sure you diligently perform a soapy test each time you work on the propane system. If you are tempted to install a 12.5kg regulator in conjunction with using a 3kg diaphragm type valve, with hose and adapter, keep in mind the regulator well not fix in the cylinder bottle valve. You might want to check with your gas cylinder bottle whether that will work with the connection.
To do a tank-to-tank refill from a 3kg cylinder bottle, you will need to construct another custom pigtail like the one described for the diaphragm valve type, with a POL fitting connector at one end joined to the POL + hose.
FAQS
Q: Why is a pigtail hose used for gas cylinder refilling?
A: A pigtail is a flexible hose used to connect gas cylinders for refilling purposes. It typically has fittings on both ends to attach to the cylinders securely.
Q: Why is a special custom pigtail necessary for tank-to-tank gas cylinder refilling?
A: Tank-to-tank refilling requires specific fittings and hose materials for safety. A custom pigtail allows for a proper connection between the cylinders, minimizing the risk of leaks or accidents.
Q: What materials are commonly used to make custom pigtails for gas cylinder refilling?
A: Stainless steel and high-pressure hoses are often used due to their durability and resistance to corrosion. These materials can withstand the high pressures involved in gas cylinder refilling.
Q: Are there different types of fittings for custom pigtails?
A: Yes, there are various types of fittings available, fittings which are commonly used for gas cylinder connections. Choosing the correct fitting for your application is very important for a secure and leak-free connection.
Q: Can I make a custom pigtail myself, or should I purchase one from a supplier?
A: Yes, it's possible to make a custom pigtail yourself if you have the necessary tools and knowledge. However, it's generally recommended to purchase one from a reputable supplier. This gives you an assurance that the pigtail meets quality and safety standards.
Q: How do I install a custom pigtail for tank-to-tank gas cylinder refilling?
A: The Installation procedures may vary depending on the specific design of the custom pigtail and the type of cylinders being connected. Be carefully and make sure that all fittings are tightened securely.
Q: What maintenance is required for custom pigtails?
A: Regular inspection for signs of wear, damage, or corrosion e.t.c Any worn or damaged parts should be replaced immediately.
Q: Can custom pigtails be used for other applications besides tank-to-tank cylinder refilling?
A: The truth is, pigtails are primarily designed for tank-to-tank refilling, they may be suitable for other applications where a high-pressure gas connection is required. However, it is important that your pigtail is compatible with the specific gas cylinder involved.
Q: Where can I purchase custom pigtails for gas cylinder refilling?
A: Custom pigtails can be purchased from various suppliers specializing in gas equipment. Or you can get it online, also available on Amazon and other retail outlets.
