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 clog a filter and/or
plug an orifice.
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.
ORB - O-Ring Boss (SAE J514)
Note straight threads
and elastomer O-Ring .
Prior to installation, to prevent abrasion during tight-
ening, lubricate O-Ring with clean hydraulic fluid.
Use no sealants (tape or liquid) on ORB 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.
