Gas Hoses FAQs

What is the Type 27 (LCC27) thread connection and how does this affect Type 21 (POL)?

In Australia, the Type 21 (POL) connection has been superseded by the LCC27 (Type 27) connection. LCC27 is now the standard connection used for leisure gas cylinder valves. Over a 10-year period, LCC27 will be phased in as old gas cylinders get re-tested and changed over. Read more

Can adaptors be used to connect cylinders with a POL connection to appliances with an LCC27 (Type 27) connection and vice versa?

Gas adaptors must NOT be used to connect an appliance with a new connection to a cylinder with an old POL valve as they give an additional leakage risk. The change between threads means that when tightening one side of the adaptor, the other end is at risk of creating a new leak.

If a customer purchases a new gas appliance with the LCC27 connection, they must replace or swap out their old LPG cylinder (with a POL valve) to one with a LCC27 connection.

Can I use a hose extension for gas outlets?

We do not recommend using hose extensions as adding an extra hose on the line will increase the chance of a leak and/or breakage. Instead, replace the hose with a longer hose. At Bromic, we supply gas hoses up to 3000mm in length.
