Liquified Petroleum (LP) gas cylinder adaptors that convert old Type 21 (POL) cylinder valves to new Type 27 (LCC27) banned in Western Australia

Following a recent gas related incident resulting in serious injury, the Director of Energy Safety has issued a prohibition order (the Order) which took effect on 29 December 2023.

The Order prohibits the sale, hire and use of LP gas cylinder adaptors that convert old Type 21 (POL) to new Type 27 in Western Australia. The Type 27 is commonly called the Leisure Cylinder Connection Type 27 (LCC27) or Quick Connect Coupling (QCC).

What is an LP gas cylinder adaptor?

It is a fitting that is used to convert an old POL cylinder valve outlet to the new LCC27, allowing the older POL cylinders to be used with the new LCC27 appliance connector.

What are the safety risks when using adaptors?

Adaptors override the improved safety features of the new LCC27 valves.

The new LCC27 valve provides a positive isolation of gas supply preventing the gas to flow unless a gastight seal or connection is formed between the valve and barbecue hose connector. These adapters undermine this safety feature which can lead to dangerous gas leaks.

The threads of LCC27 to POL adaptors are opposite, meaning a POL thread is left-hand and an LCC27 is right-hand. Tightening an LCC27 connection onto an adaptor may loosen the POL connection at the cylinder valve due to the opposing threads. This can lead to dangerous gas leaks.

These safety hazards contribute to the risk of explosion and injury when operating LP gas appliances, such as a gas-powered barbecue.

What to do

• Use a gas cylinder with the new LCC27 cylinder valve with a new LCC27 gas appliance connector; and
• Do not use an adaptor to connect your old POL gas cylinder with the new LCC27 gas appliance connector.

Reminder

• Old appliances with a POL connection hose can be used with a gas cylinder with the newer LCC27 valve.
• Replace or swap your old POL gas cylinder to a gas cylinder with the newer LCC27 valve.

More information on the safety features and transition of the newer LCC27 valve is available on the barbecue gas cylinder changes webpage.

Gas appliances can be dangerous if they aren't properly used and maintained. Gas cylinder connection, operation and maintenance should always be considered. For more information visit gas barbecue safety.
