Hydraulic Connectors and Torque
Refer to Figure 22 (a hypothetical fitting)
Leave any protective caps in place until immediately
prior to making a connection.
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 tightening,
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.
