LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing lines, perform the following
a. Clean fittings and surrounding area before disconnecting lines.
b. Cover, cap, plug, or tape lines and ports after disconnecting lines. Use cap and plug set on air
lines. When these are not available, use hand-carved wooden plugs, clean rags (item 10,
Ensure that new and used parts are clean before installing.
d. Wait to remove covers, caps, plugs, or tape from lines and ports until just before installing
Apply antiseize tape only to pipe threads of male fittings of air
system or damage to air valves may result.
When connecting air lines and fittings without compression sleeves or packings, antiseize tape
(item 17, WP 0085) may be used to keep connections from leaking. Use as follows:
a. Ensure that threads are clean and dry.
b. 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 overtighten or use power tools to tighten fittings
taped with antiseize tape. Over tightening could damage
fitting threads and cause connection to leak.
d. Using hand tools, tighten fittings.
