Reference Information
Connector Identification
Refer to Figure 27 (a hypothetical fitting)
Leave any protective caps in place until immediately prior
to making a connection.
Abbreviations
NPT - National Pipe Thread
Note tapered threads, no cone/flare, and no O-ring.
Apply liquid pipe sealant for hydraulic applications
(do not use tape sealant, which can foul filters).
JIC - Joint Industry Conference (SAE J514)
Note straight threads
and the 37
° cone on
“M” fittings (or 37
° flare on “F” fittings). Use no
sealants (tape or liquid) on JIC fittings.
Over-Torque Leak Risk:
JIC (Joint Industry Conference 37
° Flare) fittings do not
require high torque. Excess torque causes leaks. JIC
fittings do not require sealant.
ORB - O-ring Boss (SAE J514)
Note straight threads
and elastomer O-ring .
Prior to installation, to prevent abrasion during
tightening, lubricate O-ring with clean hydraulic fluid.
Use no sealants (tape or liquid) on JIC fittings.
ORB fittings that need orientation, such as the ell
depicted, also have a washer
and jam nut
(“adjustable thread port stud”). Back jam nut away
from washer. Thread fitting into receptacle until
O-ring contacts seat. Unscrew fitting to desired
orientation. Tighten jam nut to torque specification.

High Pressure Fluid and Equipment Damage Hazards:
Bleed only at JIC and NPT fittings.
Never try to bleed a QD (Quick Disconnect) fitting.
Avoid bleeding at ORB fittings. The O-ring is likely to be torn
if any pressure remains in the circuit.
