Which Olive - Brass or Copper?

[wild nomad]

Hi There,

Was wondering if anyone knew which olive is the best one to use - brass or copper? Have been using both for a while now and thought I'd ask some opinions on the matter.

Copper for me

Copper all day long!
I always carry 15 and 22mm copper olives on the van and swap the brass ones that come with some fittings......a bit more of an expense but worth the peace of mind! Plus they don't need locking up as tight as brass!

Plastic. Our pressures are up to 5 times greater in oz, and everyone has used plastic for decades with no issue. In very high heat applications use copper

Copper on cold and brass on heating and hot water and copper on plastic

brass for high temps, copper for most things.
