These torques are not recommended for tubes of 12.7 mm ( 0.5 in ) OD and larger with wall thickness of 0.89 mm
( 0.035 in ) or less. The torque is specified for 0.89 mm ( 0.035 in ) wall tubes on each application individually. Before
installing and torquing 37° flared fittings, clean the face of the flare and threads with a cleaning solvent or Loctite®
brand cleaner, and apply hydraulic sealant Loctite® 569™ to the 37° flare and the threads. Install fitting, and torque
to specified torque, loosen fitting and re-torque to specifications.
