Installing Hydraulic Fittings and Hoses
NOTE: Overtightening JIC hose fitting ends
will result in a fractured fitting.
DO NOT
use thread sealant/tape on fittings or hoses.
This could damage the product. Always use two
wrenches, or a wrench and pliers, to ensure proper
alignment and tightening of fittings and hoses.
Procedure for Installing SAE O‑Ring Fittings
in Valve Block and Rams:
1.
Turn jam nut on fitting as far back as possible.
2.
Lubricate the O-ring with clean hydraulic fluid.
3.
Screw the fitting into the port by hand until the
washer contacts the port face and shoulder of
the jam nut threads.
4.
Unscrew the fitting to the proper position—no
more than one full turn.
5.
Using a wrench and pliers, hold the fitting
body in position and tighten the jam nut until
the washer again contacts the port face, then
tighten an additional ⅛ to ¼ turn to lock the
fitting in place. Final torque on the jam nut
should be approximately 20 ft‑lb.
Procedure for Installing Hydraulic Hoses:
1.
Screw the flare nut onto the fitting flare and
hand tighten.
2. Align the hose so there are no twists or sharp
bends and so it will not be pinched or pulled
by moving parts.
3. Using a wrench and pliers, hold the hose in
position and tighten the flare nut ⅛ to ¼ turn
beyond hand tight. Final torque on the flare
nut should be approximately 20 ft‑lb.
4. Reinstall any protective hose wraps in their
original positions.
