Good evening all,
My boiler is fitted with 5/16 x 26 clack valve mounts (presumably the maker wanted course threads to avoid cross threading, or perhaps he just had a set of BSB taps and dies!)
Stuart Models offer a 5/16 x 26 threaded clack with 3/16" pipe connection – so a straight 'plug and play' available.
Can anyone advise what the lift of these clacks is like, and if they are suitable for use with injectors (11oz or 3/4 pint).
Kind regards,
David
