Typical hose end to fitting connection:
Typical o-ring sealed port connection:
Hose End
Connect hose end to 37-degree flare side of union.
Do not connect hose end to cutoff side of union!
O-ring sealed AN style port
O-ring
(Install on union fitting between back of
threads and face of hex nut.)
Typically the ORB (O-ring) side of the union is
installed in the port, leaving the 37-degree flare
side for your hose end connection. In some
cases you’ll install an O-ring on the flare side of
the fitting and use it as a union.
For example, in some systems an ORB to Flare
fitting is used to connect the fuel pump and filter
together, in which case you always install the
ORB side into the fuel pump and the flare side
with O-ring added into the filter.
