Are brass stop ends for water the same as for use on gas?

If you are talking about brass compression fittings, the answer's yes.
Be wary you don't overtighten them; if you do, they'll never seal. Please check for leaks with leak detection fluid. Washing up liquid tends to have ammonia, which attacks the brass.

Thanks, its in a house so i will get a Corgi person to check it. Just need to remove old gas fire urgently.

It depends where it is situated on "DOMESTIC GAS" instalations the use of compression fittings isn`t allowed in concealed places eg under floor boards in pipe boxes and voids.
soldered caps can be used.

Not usually.
The ones for water use brass olives, gas should have copper olives.

I think that because it's in a house you will need to get a CORGI person to do it.
Do you have the kit to check that there is no leak on the system before the disconnection , and also after the disconnection? If you are not able to do that test then you certainly are not competent to do the job.
The law has changed since I was a 'Gas man', then you only had to prove competency, I think now you have to be CORGI registered to work on domestic dwellings.
If not then you can't do the job competently.

Pete, I don't want to seem like I know better than any experienced plumber, my gas experience is mostly from fitting and repairing on boats, so to meet the BSS cert requirements. They explicitly require copper olives, because the copper makes a better seal.
I've found that I had to buy ordinary compression fittings, and then buy the copper olives separately.
Can I suggest that you fit a bubble tester? These are fantastic bits of kit, allow anyone to test for gas leaks just by holding down a button. ASAP sell them.
Oh, another quirk of BSS - no soldered joints allowed. Hard/silver soldered are ok. Otherwise, they must be compression.

Hi Alastairdent
I am not a plumber but a corgy registered gas engineer and British gas supply me with all the pipe & fittings I use,
most with brass olives for "DOMESTIC INSTALATIONS"as stated not marine .

It's in a house! So Gas Safety Regs apply (or whatever they are called now)

All sorted now, used a plastic speedfit stopend and checked with lighter and no leak. great.

What you have done is very dangerous. You cannot use plastic fittings for above ground gas work.
The reason being is that they are not fireproof.

Just to drift the thread a bit... if you wanted to have the gas system on your boat checked out, could a normal corgi guy do it or do you need a marine specialist?

If you need a BSS cert, then you need a corgi guy who knows BSS regs - hard to find.
Otherwise, no, any competent corgi reg bloke.

I was told boat/caravan systems are different to Corgi regs. ie different cert.

Corgi registration is not a blanket certificate. There are sub sections.
Any old corgi chap will not do - he has to possess the relevant cert. eg.
boilers
cookers
lpg
lpg marine etc.
Not all gas fitters have all certs.
Make sure your chap has the right cert.
With regard to the brass / copper olive discussion above - I seem to remember that there is a different metals / corrosion factor for the marine market ?
Or maybe the memory is playing tricks ???
Soldering is OK as long as it is hard solder - ordinary domestic lead/tin solder is too low in melting point for marine purposes.
