SECTION VII.
PREFORMED PACKINGS
3-19.
GENERAL
Preformed packings are used to seal lines, connections between lines, and containment areas.
After a packing is
installed, it absorbs a small amount of the fluid within the line and expands to prevent leaking.
In repair of lines and
components damaged in battle, it may become necessary to remove and install saturated preformed packings.
A
procedure is available to recondition used preformed packings if standard replacements are not available.
