Is it Ok to use brass compression fittings in an oil supply line.

Looking at the BES website ther are flared fittings (a la car brakes
available as well).

I have to run a feed to oil fired boiler. I intend to do 10mm copper
from tank to fire valve (1st+2nd 10mm to 1/4" BSP convertion) then
10mm to isolation valve (3rd & 4th 10mm to 1/4bsp conversion) then
10mm into boiler (external grant) where it gets converted to 2/8" BSP
to connect to supplied flexible line. The later seems rather long at
900mm given the manufacturers statement that it should not go outside
the boiler case.

Overall supply line is about 5 meters.

Yes, it is AFAIK. I have.

Me too! Can't find anyone to commission the thing, but it all seems to
work and no leaks.

When I installed ours (a Grant), Grant sent out an engineer to
commission it as part of the deal.

I think in theory Worcester will do the same thing, but not as part of
the deal. That's my next option I think. Or buy a flue gas analyser :-)

I don't know specifically. However, a lever ball isolation valve I bought
once had tick marks against Water, Gas, Oil and Steam. It had compression
joints.

AIUI they're OK for gravity systems, but if the boiler (or an oil lifter) is
sucking the oil along then you should use manipulative (flared, bundy-type)
fittings as these are less likely to let in air. The OFTEC web site has some
useful technical docs.

And what do these meters measure? ;-)

Experiments to demonstrate the existence of Sod's Law by dropping
slices of buttered toast all failed. That's Sod's Law.

Sorry 5 metres in length from oil tank to boiler.

Thanks for responses. I also tried to get soft copper olives as that
is what they use in diesel lines on narrow boats, where leaks end up
in bilges. Nice and squishy to fill the compression joints. As most
narrow boats use imperial sizes, which I suspect is gas stuff.
