INSTALLATION OF FITTINGS
N OT E
Tightening sequence of the fasteners that attach tube assembly or hose assembly to the machine is very crit-
ical to proper function of machine. Sealing surfaces of tube assembly or hose assembly should be secured
squarely. Sealing surfaces of the tube assembly or hose assembly should be tightened to the serviced compo-
nent (control valve, cylinder, hydraulic motor, etc.). Perform this procedure prior to final tightening of any
clamps or slips that are used to fasten the tube assembly or hose assembly to machine.
Fittings have different connections. Fittings may have two completely different ends. Use proper torque for end of fit-
ting. The following list contains some common types of fittings:
Straight Thread O-Ring (STOR)
Adjustable Straight Thread O-Ring (STOR)
O-Ring Face Seal (ORFS)
Tapered Pipe Thread (NPT and NPTF)
37 Degree Flare Fitting
45 Degree Flare Fitting
45 Degree Inverted Flare Fitting
