Cheers friends, greatly appreciate your assistance
In hindsight I probably should have just asked for the OD on the male joint component since that's the end I'm trying to match and would have tolerance control over.
But based on the dimensions you kind folks supplied for the Tornado head, I'm guestimating the male jointed base is ~9MM OD, with 1MM wall O rings, ~half recessed, which is then being compressed into the ~9.5-9.76 female head?
It's a new high surface area design I came up with based on fluid expansion.
Currently the design is 4" (100MM) long with over 8" squared of internal surface area.
The idea is to do something effective in function but simple enough to manage the price point.
I'll try to post some initial renderings briefly, I just need to finish up a few things.
Appreciate your interest FC!
