[kevplumb]

in which case you need a couple of these

put them on the pipe and the flexi will screw straight on


15 compression x 1/2"" bsp male

But is the male designed flat to bed against the washer
And while you're here can I trust the thread + 2 Oseal tap fix and should I have used vaseline

 

[kevplumb]

yes the male end is flat

as for the vaseline it's ok on o rings not washers
