ADAPTER INSTALLATION PROCESS
OM 0495SB-A [56]
JIC THREAD IDENTIFICATION & TORQUE
JIC flare fittings seal with metal to metal contact between the flared nose of the fitting and the flared tube
face in the female connection.
The minimum torque values listed are to provide a benchmark that give optimum results for leak free
connections. Actual torque values should be based on individual application.
NOTE: Do not apply thread sealant (teflon tape) on the JIC threads.
Leaks can result from vibration, thermal cycling and from loads being supported by the connection (i.e.
using the fitting in the connection to support mechanical loads).
IMPORTANT: Use the lowest torque value from the chart when wet torquing.
RECOMMENDED ASSEMBLY
STEP 1: Inspect for possible contamination or
damage from shipping or handling. Sealing surface
should be smooth.
STEP 2: Lubricate the threads and the entire
surface of the cone with hydraulic fluid or a light
lubricant.
STEP 3: Align mating components for hand
connection and turn flare nut until sealing surfaces
make full contact.
STEP 4: Torque nut to the values shown in the
above table.
STEP 5: When torquing nut onto a straight flared
fitting, it may be necessary to also place a wrench
on the flared fitting wrench pad to prevent it from
turning during assembly.
ALTERNATE ASSEMBLY METHOD
STEP 1: Inspect for possible contamination or
damage from shipping or handling. Sealing
surface should be smooth.
STEP 2: Lubricate the threads and the entire
surface of the cone with hydraulic fluid or a light
lubricant.
STEP 3: Align mating components for hand
connection and turn flare nut until sealing
surfaces make full contact.
STEP 4: Lightly wrench tighten the nut until
there is resistance.
STEP 5: Place a wrench on wrench pad next to
nut as near the 6 o'clock position as possible.
STEP 6: Place second wrench on nut as near
the 3 o'clock position as possible.
STEP 7: Turn nut clockwise to no less than the
4 o'clock position, but no more than the 6 o'clock
position. Required rotation generally decreases
as size increases.
