Olives for compression fittings
 

I've noticed two different types of these; some are apparently made of
brass and have a completely rounded external profile, whereas others
seem to be copper, and have flat chamfers at either end.

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

Thanks
David

I wondered about that. A lot of the fittings from the plumbers merchant
come with copper ones for some reason, but you can only buy copper ones
in large quantities and the sheds only seem to have brass ones.
Brass are harder, and apparently give more support to the pipes.
Copper are softer, and seem to require less tightening.
I'm sure both should work OK.

Anyone else enlighten us on this ?

I think copper ones are ok on plastic (with the insert) but not brass these
are too hard

Brass for gas couplings i.e fires ect and copper for water pipes i.e taps
ect.

Doesn't explain why its much harder to get the copper ones than brass,
round my way anyway.
You would have thought more water is done than gas. I think compression
for gas is not
a good idea anyway.

Copper olives seem to come with fittings which are
all plastic. Eg, Some Triton electric showers.
Instructions= "hand tighten only" On our bleeding
mains pressure? You must be joking.

I notice also the copper olives don't work very
well if you try to use them a second time. Probably
work-hardening of the copper.

Why?
Dunno !
I thought I heard it said on this group, and decided that a small leak
is more
likely with gas/compression, especially if the pipes got stressed.
But I was simply justifying to myself what I had heard !

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".

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.

Get an olive removal tool:

Copper olives come off very easily.

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.

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.

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

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).

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.

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.

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.
