Regulator type
Some cylinders use clip-on regulators and others use screw-fit regulators. A clear photo of the current regulator normally makes matching easier.
Gas fittings guide
Bottled gas fittings made simpler.
Home bottled gas can be confusing: clip-on regulators, screw-fit valves, patio gas, butane, propane, hoses and different appliance labels. This guide helps Dublin home users know what details to send before ordering.
What matters
The fitting must match the appliance and bottle.
For most home users the important parts are the gas type, the regulator connection, the hose condition and whether the appliance is suitable for propane, butane or patio gas.
Hose condition
Do not use cracked, loose, burnt, hardened or damaged hoses. If the hose looks questionable, stop and get it checked before using the appliance.
Appliance label
The appliance label often shows the approved gas type and pressure. Send a photo of it if you are unsure which cylinder or fitting is needed.
Safety first
If you smell gas, turn the cylinder off if safe, keep flames and switches away, ventilate the area and get qualified help. Do not keep testing it.
Butane 11.34KG
Usually matched with a butane clip-on regulator for compatible portable cabinet heaters and similar appliances.
Patio and Gaslight bottles
Often matched with a patio propane clip-on regulator. Send a photo if the appliance or old bottle is not clear.
Propane screw-valve bottles
Common for 10.89KG, 19KG, 34KG and 47KG propane cylinders. Fixed appliances need qualified assessment.
Appliance label
Shows approved gas type, pressure, model number and any appliance-specific requirements.
Current regulator
Show the full regulator, hose and bottle connection so similar-looking fittings can be told apart.
Bottle valve/top
Show the top of the old cylinder if you have one, including the valve and any visible bottle label.
This is a matching guide, not DIY gas fitting instruction.
The Gas Guy Dublin can help identify likely cylinder and fitting requirements from photos. Any fixed appliance installation, repair, alteration or unsafe setup should be handled by a suitably qualified gas professional.
If you smell gas from a bottle, treat it as urgent.
Do not keep testing the appliance. Follow these LPG cylinder safety steps if it is safe to do so:
- Extinguish naked flames and remove ignition sources.
- Turn off gas appliances and do not use electrical switches.
- Turn off the gas supply at the cylinder, tank, pipe or meter if safe.
- If indoors, open doors and windows to ventilate.
- If a butane cylinder is leaking indoors, move it outside to a well-ventilated location only if safe.
- Move away from the leak before calling for emergency help.
For Flogas LPG cylinders call 041 214 9600. For Calor ROI cylinders call 01 291 6229. For mains natural gas call Gas Networks Ireland on 1800 20 50 50.

Common home setups
Which bottle are you trying to connect?
These examples help narrow the conversation before you order. If the appliance has a regulator already fitted, send a photo of it with the cylinder connection visible.
BBQ and patio heater
Often uses patio gas with a patio propane clip-on regulator. The appliance label and existing connection decide what is suitable.
Portable cabinet heater
Often uses butane with a butane clip-on regulator. Check the appliance label before changing cylinder type or regulator.
Home and outdoor appliances
Propane screw-fit regulators are common for 10.89KG, 19KG, 34KG and 47KG cylinders. Fixed appliances need professional assessment.
Lightweight gas bottles
Gaslight 5KG and 10KG commonly match a patio-style propane clip-on regulator. Send photos so the connection can be checked.
Before you order
Send the right details once.
A few photos usually avoid the wrong bottle arriving. This is especially useful when replacing an old cylinder, switching from one gas type to another, or ordering for a rented appliance.
Photo of the appliance label
Look for gas type, pressure, model number and any safety markings. Do not remove panels or dismantle the appliance to get it.
Photo of the regulator
Show the full regulator, connection and hose route. This helps identify clip-on, screw-fit and similar-looking connections.
Photo of the current bottle
Send the cylinder size, colour and valve connection if there is an old bottle already there.
Where it will be used
Tell us if it is for a BBQ, patio heater, mobile heater, cooker, food trailer, shed, site or commercial setting.
Helpful checks
Avoid the common fitting mistakes.
Most problems come from guessing the bottle type, reusing old hoses, or assuming every regulator fits every cylinder. These checks help customers order with better information.
Common mistakes
- Buying propane when the appliance label says butane, or the other way around.
- Assuming red, green or yellow bottles all use the same regulator connection.
- Reusing an old hose that is cracked, burnt, hardened, loose or out of date.
- Trying to connect a fixed appliance without a qualified gas professional.
- Ordering a bottle without checking whether an empty cylinder is available to exchange.
Hose condition checklist
- No cracks, splits or flattened sections.
- No burn marks, heat damage or brittle rubber.
- Hose clips are secure and not corroded.
- The hose route is not kinked, stretched or under strain.
- The appliance is used only where the manufacturer says it can be used.
Can I use propane instead of butane?
Only if the appliance is approved for it and the correct regulator is used. Send the appliance label before changing gas type.
Can you help identify the regulator?
Yes. Send clear photos of the appliance label, current regulator and bottle valve before ordering.
Do I need an empty cylinder?
Most bottle prices assume an empty exchange. The order form lets you choose with or without an empty cylinder.
Can I swap Calor for Flogas?
Yes. Flogas dealers will generally accept competitor empties (including Calor) when you buy a full Flogas bottle — which may mean no new bottle deposit in many cases. Check valve compatibility first: Gaslight uses 27 mm clip-on; many Calor bottles use 21 mm clip-on or POL screw-in. You may need a new regulator. Tell us the empty brand when ordering for doorstep exchange delivery.
Can you connect the bottle for me?
Simple bottle exchange depends on the setup. Fixed appliances, repairs, conversions and unsafe fittings need a qualified gas professional.
Not sure what fitting you have?
Send photos before ordering.
Send a photo of the appliance, label, current regulator and bottle connection. We can help you choose the right gas bottle and flag when a qualified gas professional should inspect the setup.
