Cones for union nuts
I'm hoping that someone will know this. I have looked everywhere and can't find a sensible answer.
What is the inclusive angle for tapered part of the cone for union nuts and is this the same across all sizes?
Hoping you can help.
Regards
Hi Deric ,
There is no actual standard but many model engineering applications use 60 degrees inclusive – the same as a centre drill .
90 degrees inclusive would actually be a better choice but is seldom used .

Thankyou Michael. Much appreciated
