4. Inspect ORS-ORS adapter and ORS-TF components for damage. Assure sealing surfaces
are free from all surface gouges, scratches, dirt and contaminants. Inspect O-ring to make
sure that it is properly seated in the groove and is free from damage. Apply a thin film of
compatible lubricant (clean power steering fluid) to the O-ring prior to installation.
5. Place a nut, ferrule and sleeve onto tubing, assuring that the identification groove of the ferrule
is toward the nut (
Figure 15). Assemble the nut to the ORS-ORS adapter until handtight with
the tubing fully inserted into the fitting until bottomed out. Mark the nut in relation with the
ORS-ORS adapter and tighten 1 ½ turns with a wrench (
Figure 16 to Figure 18). The ORS-TF
sleeve cannot be used to preset multiple tube assemblies. It may be used once for presetting.
CAUTION
Tubing must be fully inserted into the fitting and the nut tightened as specified above to ensure
performance and to prevent leakage and potential fitting blow-off. Excessive tightening of the
nut beyond the recommended level may affect performance.
