This is not in any way my specialist subject... I could do with converting them to 3/8 BSP but don’t know what I’m staring with here... Pretty sure Aiden will know @CPS

UNF, straight thread O ring. Same thread as JIC, you can get a simple JIC/BSP adapter, but may need to face off the taper on the JIC end so it doesn’t bottom out. might need a Dowty washer.

sorry, just had a closer look, it might be a metric, in which case it‘s not so easy. Check the thread against a UNF bolt, if it matches refer to first paragraph.

they look BSP 1/4 or 3/8, for screwing into a block rather than onto a hose end.
They are the fittings into the tilt ram valve block on the Rototilt mate - the captive sealing washers have confused me to be honest. Is that what they will be - straightforward BSP?

Yea, defo 3/8 BSP then (y) I couldn't judge if they were 1/4 or 3/8 cos i couldn't remember if you had really big hands:p

Was gonna say Sykes pickavant when I read this last night but you beat me to it. Occasionally it is handy to have the internal thread scraper on the end but most of the time they get it the way 🙂

Never saw this post first time around- apologies, I wasn’t ignoring you!
Adapters out of a Rototilt.
what were they after .... my local 'guru' at me hyd suppliers once said to me that 90% of hyd ports are BSP .... Kins. being the exception .. always metric. Hence the Q. ;) Those captive seal fittings are always a tad confusing, but'll fit where a bonded / Dowty washer won't
