I am working in New Zealand, I am currently looking for some fittings for copper piping in Aust Sizes. They are 3/8″ and 1/2″ nylon olives, i.e. olives which have ID of 3/8″ & 1/2″ and make from nylon.
I have tried many plumbing suppliers in NZ and Aust, but still no luck. Do any plumbing suppliers in Aust have them? If so please contact me.
