HYDRAULICS
TIGHTENING STRAIGHT THREAD FITTINGS
The straight thread hydraulic fittings require precise tightening. Over-tightening of the hydraulic fittings will ruin
the sealing surfaces and will require the replacement of the damaged parts.
Do not use any teflon tape or thread sealant on any JIC fittings or in o-ring port cylinders.
Proper initial tightening procedure depends on the mating parts being connected. Proceed as follows:
• An adapter fitting (37 flare) connected to a double flare tube assembly requires that the fitting be
tightened finger tight and wrenched 1/2 turn (for single flare, 1/4 turn), 150-500 in. lbs.
• An adapter fitting (37 flare) connected to a hose requires fitting to be tightened finger tight and
wrenched 1/4 turn, 150-500 in. lbs.
• An o-ring adapter fitting connected to a solid port requires the fitting to be tightened so that the backup
washer contacts the face of the boss after the fitting has been properly positioned.
To re-tighten after initial tightening, as in service work, both tube and hose connections should be tightened
finger tight and wrenched 1/4 turn, 150-500 in. lbs. O-ring fittings should be tightened as for initial assembly.
