Let’s talk catch cans/oil separators and connectors.

i’m keen to fit a catch can to my TDI, and maybe the wife’s TSI if we decide to keep it long term. I’d like to use original style fittings wherever possible.

So is anyone able to tell me the name of these style fittings? I’ll need one for the take-off at the breather, one for the intake just before the turbo. The catch can I choose (am leaning towards Provent for price and local Aus availability) may use different fittings - but that isn’t relevant just yet.

Can an anyone help with a name, and possibly an Aus seller of these hose fittings?
