Can anyone tell me the significance of the two species, and are they
interchangeable in different compression fittings?


Copper is best used where the compression fitting is used as a disconnection
device at an appliance. The brass olives can indent the pipe, copper rarely
do this. On each disconnection and re-connection a new copper olive is
used.



Yes but is there an easy way to get the old ones off?

The copper olives are pretty easy to remove. Monument sell an olive remover
tool for 15mm only, for...£25.

When I had a gas fitter around to fit the hob (freakin regs!), I
questioned his use of compression fittings instead of solder, and he
said that they have started to use compression more because "They don't
melt in a fire".

They only use them around appliances.

Time is money. 30s with a proper tool and no pipe damage or a couple
of minutes hacksaw and possible pipe damage. If I was a pro plumber I
know which I'd use and it wouldn't have lots of little teeth.

Yep about £25 for the Monument olive puller.

I heard Brutus went to mount olive?
and Popeye knocked seven bells out of him.

But they don't Most use cheap tools designed the 1920s.

A cheapo dremel clone to nearly split the olive and then a screwdriver
to finish the job (twist open the slot made by the dremel) is quite
quick and easy (and there was no room for a hacksaw).

Ive bought lots of different compression fittings and some have copper
and some have brass. I use whichever comes to hand and as far as I can
tell it doesn't make a jot of difference

Two methods:

Junior hacksaw and big flat bladed screwdriver. Cut through the olive
being careful not to touch the pipe. Put screwdriver into slot and
twist to expand/break the olive. Be aware of sharp bits of metal on
the broken olive.

Copper olives come off very easily.

Sometimes you can ease the olive off by using waterpump pliers to pull the
back of the nut towards the end of the pipe, first at one side then the
opposite.

The operative word is "sometimes".

Using a junior hacksaw cut diagonally almost but not quite right through
the olive - stop just before you'd be cutting into the pipe. Then
insert a flat blade screwdriver into the kerf and twist. The olive will
then ping off. Easy.

I do the same (ish) but it's rarely straightforward. I find the lack of
room to manouevre the saw blade and just getting a starting cut without
the saw slipping always comes into it.

If these olive pullers are as good as I've heard people say they are
then they will definitely be on my tool list.

I know I asked the question, but what I do is adjust a wrench to
slightly larger than the pipe, then use the wrench against the nut and
tap it with a hammer. Not easy and copper olives are not easy!

I'm not sure a puller would deal with an olive form a joint that has
been over tightened. I can't remember if I included a link to the
puller previously but I know the links were to 15 and 22mm olive
cutters.
