  Product Description
A 750mm butane pigtail made from stainless steel and designed specifically for caravans and motorhomes. It connects directly to a fixed Euro regulator with an M20 fitting, making it ideal for compact installations where space is tight. The 21.8mm left-hand threaded cylinder connection accepts standard butane bottles, while the M20 nut end locks straight onto your caravan's built-in regulator.

Stainless steel hoses offer genuine advantages over traditional rubber pigtails. They resist permeation, meaning no nasty smells develop over time, and they're engineered to last around 20 years rather than the 5 years you'd get from rubber. The construction prevents oil contamination in your gas system, which can damage downstream equipment like your regulator and appliances. Since these hoses are made of metal, they're significantly more robust and less prone to damage from UV or physical wear. Stainless steel pigtails do need careful coiling to avoid kinking, particularly during storage.

Installation is straightforward if you have a centralised regulator setup. Simply connect the cylinder end to your butane bottle and thread the M20 nut fitting onto your fixed regulator bulkhead. The 750mm length works well for most fixed mounting positions where the bottle sits close to the regulator. You might need a longer hose if your setup requires extra reach. Always verify your existing regulator has an M20 connection point before purchasing, as this determines compatibility.

Frequently Asked Questions

Why do stainless steel pigtails last 20 years compared to rubber at 5 years?
Rubber pigtails deteriorate over time as the material naturally degrades from exposure to temperature fluctuations, UV light, and the gases flowing through them. Stainless steel resists this degradation completely. It doesn't permeate, meaning gases and odours can't escape through the hose walls as they do with rubber. Stainless steel also prevents oil contamination from building up inside the hose, which protects your regulator and caravan appliances from damage. Under normal caravan and motorhome use, a quality stainless steel pigtail remains safe for approximately 20 years from installation.
Will a 750mm pigtail work with my caravan's fixed Euro regulator?
Yes, provided your fixed regulator has an M20 inlet connection. The M20 nut fitting on this pigtail screws directly onto M20 threaded receptacles found on standard Euro bulkhead regulators fitted to most UK caravans and motorhomes manufactured in the last 20 years. Before purchasing, check your existing regulator by looking at the caravan's external bulkhead fitting or consult your handbook. If you're unsure of your connection type, contact your caravan manufacturer or your nearest dealer for confirmation.
What is the 21.8mm LH connection and will it fit standard butane bottles?
The 21.8mm LH denotes a 21.8 millimetre left-hand threaded connection, which is the standard cylinder valve thread found on UK butane gas bottles. The LH marking means the thread rotates counter-clockwise to tighten, which is standard for all butane bottle connections as a safety feature to prevent accidental mixing with propane systems. This connection fits 4.5kg, 7.5kg and larger butane bottles fitted with standard valve blocks. Always verify your butane bottle has the correct valve type before connecting.
How should I store the stainless steel hose to prevent kinking?
Coil stainless steel hoses using a figure-eight pattern rather than wrapping them in circles. Circular coiling creates tension and twisting in the hose, which causes kinks when you unroll it. Using the figure-eight method, you alternate loops over and under each other, which releases tension naturally and allows the hose to lay flat when deployed. Store the coiled hose in a dry location away from direct sunlight and extreme temperatures. Avoid tight elastic bands or clips around the hose when stored, as these restrict flexibility and can create permanent creases in the stainless steel tubing.
Do I need to inspect the pigtail before each trip?
Yes, visual inspection before each journey is good practice. Examine the entire length of the hose for any visible damage, cracks, dents, or areas where the stainless steel braiding might be exposed. Check both connection ends to ensure nuts are tight and fittings are secure. Perform a basic leak test by applying soapy water to each connection while gas is running through the system. Bubbling indicates a leak that requires attention before travelling. Although stainless steel lasts far longer than rubber, regular checks identify any damage early and ensure safe operation throughout your caravan or motorhome's gas system.
Can I use this butane pigtail with a propane bottle instead?
No, you cannot use a butane pigtail with propane bottles. Butane and propane connections are intentionally different for safety reasons. Propane bottles use a right-hand threaded connection with different dimensions, whereas this butane pigtail features a 21.8mm left-hand thread. If you need to switch from butane to propane in your caravan or motorhome, you must purchase a separate pigtail designed specifically for propane use. However, both butane and propane can work through the same Euro regulator, so you only need to change the pigtail to switch gas types.
How do I safely connect the pigtail to my bottle and regulator?
Start by ensuring your gas bottle valve is in the off position. Take the 21.8mm LH end of the pigtail and insert it into the butane bottle's valve connection, then rotate counter-clockwise until it grips securely. You should feel resistance as the left-hand thread engages. Connect the M20 nut end to your caravan's fixed regulator by screwing it clockwise onto the threaded inlet. Hand tighten both connections initially, then use a gas spanner on the bottle connection and an adjustable spanner on the regulator nut to tighten firmly without over-tightening. Test all connections with soapy water to check for leaks before opening the gas bottle valve.
What does the 750mmmm length mean and will it reach my regulator?
750mm means the pigtail is three-quarters of a metre long from the bottle connection to the regulator connection. This length works well for caravans and motorhomes where the gas bottle is stored in a locker or cupboard positioned relatively close to the external bulkhead regulator. If your bottle sits more than 750mm away from the regulator, you'll need a longer pigtail. Conversely, if 750mm proves too long for your installation, you can carefully coil excess hose beneath the caravan or in the cupboard. Crusader produces pigtails in various lengths including 1.5 metres for installations requiring greater reach.
