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.
