The LCC27 is a new type of gas cylinder connection that is replacing the older Type 21 (or POL) fitting. The LCC27 fitting is designed to be safer and easier to use than the POL fitting.
The POL fitting relies on the user to tighten the connection, if not tightened properly, it can leak gas. Additionally, the POL fitting tightens in the opposite direction of most other threaded connections, which can be confusing for some users.
Here are some of the benefits of using the LCC27 fitting:
The new LCC27 fitting is being phased in for 9kg and 4-4.5kg LPG cylinders with POL valves. This change does not affect camping cylinders with upright 3/8 BSP fittings or large 45kg domestic cylinders. It is also not applicable to Natural Gas or small disposable Butane canisters.
The change to LCC27 valves began on April 1, 2021, when gas cylinder suppliers started fitting the new valves to new LPG cylinders.
If you have an appliance and cylinder with POL fittings, you can continue to use it as normal until your cylinder reaches its 10-year testing date. At this point, it will need to be fitted with a new LCC27 valve. The LCC27 valve is backwards-compatible, so you can continue to use the POL fitting on your appliance.
However, new appliances with the LCC27 fitting will not connect to a cylinder with a POL valve. This is important to note if you utilise an exchange program for your cylinders, as there may be a mixture of valves available for swap until they have all surpassed their 10-year re-testing requirements.
Here is a summary of the key dates for the change to LCC27 valves:
