Cuala are back-to-back AIB All-Ireland Club Senior Hurling champions.
Quick-fire second-half goals from Nicky Kenny and Mark Schutte helped the Dalkey men overcome Na Piarsaigh by 2-17 to 1-17 in their replay in O'Moore Park in Portlaoise.
The Limerick champions never gave up and that six point lead was reduced in the final quarter with Na Piarsaigh edging ahead on the stroke of 60 minutes.
It was left to dual star, Con O'Callaghan, to level the game for the eighth time.
He then won a free, which was converted by David Treacy, before laying off a pass after a super catch for Mark Schutte to secure another point for the Dublin, Leinster and once again, All Ireland champions.
