Fitting for gas hob

[TullioK]

We are having a gas hob installed by a gas safe plumber on a labour only basis and I need to source something to connect to the 1/2" male thread on the hob to the pipework. I was under the impression that any 1/2" female fitting that will join to 15mm copper by solder or compression fitting would be fine, but I notice a lot of fittings in DIY stores say 'not suitable for gas' on the pack. Searching online and I haven't found anything that says specifically that it is suitable for gas. So my first question is: where should I go to source a fitting like this which is suitable for gas?

Second question: I notice a lot of flexible gas connector hoses for sale. Is this what would normally be used to connect a hob or is rigid pipework also normal? A flexi hose certainly seems easy if the hob ever needs to be temporarily removed in the future.

Third question (of lower importance): will a 10m run of pipe to a 5 burner hob be OK in 15mm or would I benefit from 22mm?

Thanks in advance!

As long as it doesn't say "not suitable for gas" anyone will do.

Follow the manufacturer's instructions.

Yes.

Hob fittings are as basic as they get, if your plumber doesn't have these already there is something wrong.

When an oven or drawer unit is fitted below the hob is is highly unlikely you can comply with the hose manufacturers requirements hence rigid copper pipework is universally used.
Where you do come across hoses it is 99.99% fitted by illegal gas workers.

I would hope any gas fitted turning up to fit a hob would carry a standard 1/2 FI fitting.

Thanks to you both. That's all useful to know.

I think I've found a suitable product now https://www.screwfix.com/p/endex-brass-end-feed-adapting-female-coupler-15mm-x/70202

Ha yes, you would hope so. He is semi-retired now and mostly does boilers so I guess he doesn't have a huge stock of parts these days.

I am also semi retired, but I would not expect the customer to supply the fittings.
I smell bulls hit.

It's because gas and water tend to use different threads

Is a gas tap also normally installed adjacent to a hob - there is one under our hob.

Normally under the hob, it is a service valve not an emergency control
