Paul, if it's not too late, my comments on your drawings:

My O-ring book shows only a .125 groove width where you show a .146 groove
width-I don't know which would be better.

The ferrule shows to be bored to 1.395 dia.  What size of tube were you
planning to put in there?

The sleave should have a good bevel on the inside to aid in slipping it over
the O rings.  Otherwise, it's a bitch to assemble.

For what it's worth.

I have an Apple Rubber catalog/book on O-rings. Are you using a Parker
catalog?  I need to get a Parker catalog. I expect the width is not all
that critical. 

The tube size is 1 3/8 or 1.375 inch OD .049 wall tubing. I gave it an 
extra .020 on the  dia. or .010 on each side for slightly oval shaped tubes 
and epoxy bond thickness. I left lots of meat so it can be bored out to 
1.5 inch for water pump hose barbs.

Good point on the sleeve bevel. Hold on Keith I will revise the drawing
as per that suggestion.
