Wanted: water fitting replacement for 860XL espresso maker.

My 860XL espresso maker has a broken (straight-through) water fitting connected to the milk steamer/frother valve. Water line is ~4mm OD. Replacement part is not available from Breville or aftermarket sources. Anyone have one laying around? I have photos of old/broken fitting if needed.
