The main BBQ gas connectors in Australia are LCC27 and POL connectors for portable LPG cylinders, and gas bayonet or approved quick-connect fittings for compatible BBQs connected to a fixed gas supply.
LCC27 and POL cylinder connectors
LCC27 is the current portable LPG cylinder connection. POL, also called Type 21, is the older connection still used on some BBQ regulator hoses.
| Feature | LCC27 | POL |
|---|---|---|
| Connection | Fits over the valve’s external thread | Screws into the valve’s internal thread |
| Appearance | Usually has a large plastic nut or handwheel | Has a narrower threaded fitting that enters the valve |
| Tightening | Clockwise | Anticlockwise because it has a left-hand thread |
| Tools | Hand-tightened | Follow the manufacturer’s instructions; many BBQ versions have a handwheel |
A current Australian LCC27 cylinder valve also has an internal POL thread, so it can accept either connector. An older POL-only cylinder valve does not have the external thread needed for an LCC27 connector.
Never force either fitting or use an improvised adaptor.
Gas bayonet and quick-connect fittings
A gas bayonet or approved quick-connect fitting connects a compatible BBQ hose to an installed gas point rather than directly to a portable cylinder. The appliance hose plug must match the gas-point socket.
These fittings are commonly used as a natural gas BBQ connector, but the fitting alone does not prove which fuel is supplied. Depending on the property, a fixed service may supply natural gas or LPG.
The BBQ’s data plate, hose, regulator arrangement, gas type and required supply pressure must all match the installation. Appliance conversion and fixed gas work are not DIY tasks.
Check compatibility before use
Check the BBQ data plate, manufacturer’s instructions, regulator, hose and available supply labels. Do not use a connector that is damaged, corroded or does not fit cleanly, and never check for leaks with a flame. These warning signs can indicate gas fitting problems rather than a simple connector mismatch.
If you smell gas or suspect a leak, stop using the BBQ, avoid flames, sparks and electrical switches, and move away from the area. Do not attempt repairs or conversion work. Call 000 for fire, injury or immediate danger; otherwise, contact the gas distributor or LPG supplier’s emergency service from a safe location. A licensed Sydney gas-leak team can test and repair the installation once the immediate danger has been managed.
For non-emergency advice about a new fixed bayonet or BBQ connection, contact our Sydney gas-point installation team to confirm the appliance, fuel, hose and socket are compatible.
