A 'cross' by definition has 4 legs so I got that and "Male O-ring boss"
isn't as clear but the fitting assembly I suggested would accept an o-ring
on each of the four legs where the 815's are threaded into the 937
yielding the 4 male 37 degree flared cones that stands proud. An O-ring
will fit over those male flares to seat against the shoulder of the 815.
See attached fitting chart. Ebay has many AN fittings in alum and hit/miss
in SS and steel.

Just to be certain we are talking about the same thing; this is a four-way
cross with a male o-ring boss (ORB) on each leg?
If so I’d be happy to get six.

I have many of them we don't use. I can box them up and ship them to you

Allan aircraft makes them for hundreds a piece. You can also make them
yourself with an AS5202 port contour cutter from McMaster

I’ve spent most of a week looking for a AN-4 cross (aluminum or
stainless) that will accept o-rings on each mating surface, so far w/o
success.
Is such a part made? Anyone know where I might order several?
Special bonus if one leg were an NPT male....
Slow leaks are proving to be a problem in the buildup of my pneumatic
separation system; the actuated burst valve holds pressure perfectly but
the racing grade AN-4 swivel connectors are leaking down over about 20
minutes at the swivel side.
