Aotearoa folks, it looks like Mitre 10 is getting rid of their brass hose fittings. On the weekend I visited and every single Jobmate brass hose fitting had been removed from the shelf and was in a jumbled box of bargain bits.
These are all Gardena compatible. Get rid of your plastic fittings and replace them with something that has less microplastics. (There are still some minor nylon pieces in them.)
