Section 4: Setup
4.0 CONNECTING 4” J-FORCE GEN II
Prior to installing the 4” J-Force Gen II onto the hose, flush the system to
clear any debris.
For 22,000 psi operation (3/4” Type M Male, 9/16”MP LH/RH Inlet)
1. Apply anti-seize compound to the threads of the Type M connection or
to the male 9/16”MP hose/lance end.
2. Install the JF4X22 and tighten to 90 lb-ft.
For 15,000 psi operation (NPT Female Inlet)
1. Apply 3-4 wraps of Teflon thread sealant tape to the male NPT hose
end.
2. Apply anti-seize compound over the sealant tape for protection against
galling in connection threads.
3. Tighten the connection 1-1/2 to 2 turns past hand tight. All NPT pipe
connections should have a minimum thread engagement of 4 threads.
4.1 Prior to installing nozzles in the 4” J-Force Gen II, turn on the pump
and run at low pressure to flush debris from the system. Refer to nozzle
charts in Appendix C to select the proper nozzle configuration for your
application.
NOTE:
Nozzle configurations must be carefully selected to ensure that
they provide the necessary pull and torque. If a non-standard configura-
tion is required, contact a Jetstream representative to verify that it is safe
and that the tool will function properly.
4.2 An anti-withdrawal device (backout preventer) should be used to
prevent the tool from accidentally exiting the pipe under high pressure.
Hose restraints (whip checks) should be used at all high pressure hose
connections including the fluid end discharge. See Appendix B for a list of
backout preventers.
4.3 Contact Jetstream representative for assistance.
