Quick Question,

It seems there are different knids of olives used in compression
fittings.

Ones with a rounded curved profile and ones with a conical taper on
each end.

Can they be used interchangeably??

I'm replacing a sink this afternoon, the old sink has been removed and
the ball o fix valves have been left on the hot & cold supplies, I'll
have to get some olives and don't know which to get.

Ta.
