LINES AND PORTS.
To keep dirt from contaminating fluid systems when removing and installing lines, perform the following
Clean fittings and surrounding area before disconnecting lines
Cover, cap, plug, or tape lines and ports after disconnecting lines. Use cap and plug set
(item 1, Appendix I) on hydraulic lines. When these are not available, use hand-carved wooden plugs, clean rags
(Item 15, Appendix F). duct tape (Item 21, Appendix F), or other similar materials to prevent dirt from entering sys-
Ensure that new and used parts are clean before installing.
Wait to remove cover, cap, plug, or tape from lines and ports until just before installing
DO NOT use antiseize tape on air lines. Damage to air valves may result if anti-
seize tape is used.
Apply antiseize tape only to pipe threads of male fittings of hydraulic system.
When connecting hydraulic lines and fittings without compression sleeves or packings, antiseize tape
(Item 20, Appendix F) may be used to keep connections from leaking. Use as follows:
Ensure that threads are clean
Start antiseize tape one or two
threads from small or leading edge of fitting, joining
tape together with an overlap of about 1/8 in. (3.18
mm) for fittings with fine threads. For fittings with
coarse threads. tape should be wrapped around
threads two or three times.
Tightly wrap antiseize tape in
same direction as you would tighten a nut. Tape must
be pressed into threads without cutting or ripping.
DO NOT exceed specified torque or use power tools to tighten fittings taped with
antiseize tape. Over tightening could damage fitting threads and cause connection
Using hand tools, tighten fittings to specified torque.
