Heads seacock: thread size?

[Nigel]

I need to replace the larger size of seacock from the heads on my Bavaria 47. Does anyone know what size thread they are?

I don't know the thread count but I know I replaced 2 of the big through hull/sea cocks with 1 1/2".   They were the same size as the original ones.  I'm not sure if you're looking for the diameter or the thread count.

I have a photo of all the valves and numbers, the threads are BSP standard so look up the standard:-


BRASS BALL VALVES
TECHNICAL & DIMENSIONAL DATA
SPECIFICATIONS :
FULL BORE BALL VALVE , TWO PIECE DESIGN, LEVER OPERATED,
SCREWED FEMALE BSP PARALLEL THREADS TO BS21.

Look at Photo and put numbers into Google.
