I was looking at buying a pizza oven and the search found an oven with a new gas fitting for a 9 or 4.5 kg gas bottle.

As the title says it is an LCC 27.

Basically this new valve will not allow gas to discharge if the fitting is loose on the bottle.

The new bottles are identified by a black knob. I hope this is ok to describe it this way.

You may read all about them in this link.

We may find new vans being fitted with these bottles so it is important with *swap and go services* that you swap for the correct bottle
