What is the LCC27?

LCC27 is the acronym for the Leisure Cylinder Connection Type 27.  It is an evolution of the current portable gas appliance connection the Type 21 or as it is commonly referred to a POL connection.

About the current POL valve

The current Type 21 or POL connection is fitted to 8.5 kg or 3.7 kg LPG leisure cylinders.   It has a handwheel operated valve, an internal thread for connecting to the appliance, a pressure relief valve, ullage filling and a dip tube.

What has evolved in the LCC27?

The LCC27 cylinder valve retains all of the POL features including the internal thread for connecting to your gas appliance.  It also has an easy-to-use right hand threaded external ACME connection, a thermal cut-out when used with the correct gas hose connection and a back check valve that must be engaged by having a positive connection to the appliance hose before gas can flow.

How can I tell the difference?

Has a visible external thread on the valve Does not have a external thread on the valve

What does the new appliance connection look like?

You can tell the new connection because of the broader handwheel and sheltered brass connection

Why are we changing?

This change is a collaboration between the Gas Technical Regulators Committee (GTRC), the Gas Appliance Manufacturers Association of Australia (GAMAA) and Gas Energy Australia (GEA) to improve the consumer experience and maximise safety outcomes.   This collaboration requested changes be made to Australian Standards that will benefit everyone.  The original project proposal by GEA to Standards Australia is available on the Standards Australia website.

When will I see the new valve and appliance connection?

You may see the LCC27 cylinder in stores or exchange cages from 1 April 2021. The details on regulatory approvals for the sale of valves and appliances can be found in the GTRC Technical Guidance Bulletin 14 LPG Cylinder connection transition.

Will my old barbecue still work?

Yes, the LCC27 retains all of the connection features of the POL connection on your portable gas appliance.  The LCC27 is also designed to work specifically with a new easier to use appliance connection.

No thread on outside of valve

Do I need an adaptor?

No you don’t need an adaptor and they are specifically precluded from use in the Australian Standards.  The LCC27 can be used with both a POL and LCC27 appliance connection.  A LCC27 appliance connection can only be used with a LCC27 valved cylinder.

When making a selection for your next LPG portable appliance remember

The next time you need more gas for your barbecue. “when making your selection match your appliance connection”.
