Check components to ensure that fitting and port threads are free of burrs, nicks and scratches, or any form ofcontamination.2. Apply pipe thread sealant (paste type) to external pipe threads.3. Thread fitting into port until hand-tight.4. Torque connector to appropriate torque angle. The Turns From Finger Tight (T.F.F.T.) values are shown inTable 5.14, page 107. Make sure that tube end of a shaped connector (typically 45º or 90º) is aligned to receiveincoming tube or hose assembly. Always finish alignment of fitting in tightening direction. Never back off(loosen) pipe threaded connectors to achieve alignment.5. Clean all residue and any excess thread conditioner with appropriate cleaner.6. Assess final condition of fitting. Pay special attention to possibility of cracks to port opening.7. Mark final position of fitting. If a fitting leaks, disassemble fitting and check for damage.NOTE:Overtorque failure of fittings may not be evident until fittings are disassembled.Table 5.14 Hydraulic Fitting Pipe ThreadTapered Pipe Thread Size Recommended T.F.F.T.
