Just checked Harry.
I have the 12mm fittings but the motorhome tap tail is not the same as a household one, its smaller.
Is this what you are after? I'd need to check to see if there is a 12mm to household size thread.
There is a stockist in Dublin, see https://www.flomax.ie/Catalogu…ht-Adaptor
I think this is what you require.
These are the ones I keep, but won't fit household tails.
