INSTALLATION OF ADJUSTABLE FITTINGS
IN STRAIGHT THREAD O RING BOSSES
1. Lubricate the O-ring by coat ing it with a light oil or

These torques are not recommended for tubes of 12.7 mm (1/2 in) OD and larger with wall thickness of 0.889 mm
(0.035 in) or less. The torque is specied for 0.889 mm (0.035 in) wall tubes on each application individually.
Before installing and torquing 37 ° ared ttings, clean the face of the are and threads with a clean solvent or Loctit e
cleaner and apply hydraulic sealant L
OCTITE
® 569 to the 37 ° are and the threads.
Install tting and torque to specied torque, loosen tting and retorque to specications.
