"O" ring type seal fittings have been used on rack and pinion and integral gear power steering hose line connections since 1980.
Fitting torque specification is 27 N-m (20 lbs. ft.). If a leak is experienced at the fitting area when properly tightened, this condition may be caused by a
damaged fitting "O" ring. Inspect the "O" ring for damage, pipe end for cracks, fitting threads for damage and replace as required.
DO NOT EXCEED fitting torque specification. Additional torque will not increase "O" ring sealing ability and may result in cracking the connection
boss on aluminum gear housings. If a leak is experienced at the connection area with a new undamaged "O" ring under correct torque, inspect housing
boss for possible porosity. A porosity condition will require housing or short gear replacement.
