Dave,

Yeah, I've been to those exact pages, & will note for the record that
none of those pages mention an o-ring for sale, however, the pictures do
indicate that the parts come with said o-ring. If not, like I said, I
would like to know the particulars for when I go a calling the very well
informed A&S sales people (tongue firmly in cheek here).

OK, a hydraulic guy here ... don't know if oyu are after rubber type
or size.

These are what are normally called "SAE" fittings and use (usually) a
90 durometer nitirle material. It looks like they are SAE #6 (thread
is 3/8-24), but just for grins,

size thrd ID section
-4 7/16-20 .351 .072
-5 1/2-20 .414 .072
-6 9/16-20 .468 .078
-8 3/4-16 .644 .087

These do not appear to be in the AS568A dash number series but are
available at any fluid power fitting source.
