c. Ensure that flat face of the mating flange comes in full contact with O-ring.
d. Thread tube or hose nut until hand-tight. The nut should turn freely until it is bottomed out. Torque fitting further to the specified number of F.F.F.T (Flats From Finger Tight), or to a given torque value in the table shown in the opposite column.
NOTE: If available, always hold the hex on the fitting body to prevent unwanted rotation of fitting body and hose when tightening the fitting nut.
e. When assembling unions or two hosed together, three wrenches will be required.
