WARNING
Leave 1 1/2 threads exposed on fitting when applying teflon tape. This will ensure that no teflon tape will
hang down inside the air system. Teflon tape should be wrapped in such a manner that when the fitting is
tightened the tape will not loosen. Failure to wrap teflon tape correctly may result in contamination or
blockage of the air system and subsequent possible injury or death to the diver.
NOTE
Install teflon tape on all fittings and valve threads.
WARNING
Cleanliness is imperative in maintaining and handling diving air system components. All tools and parts
must be kept free of oil, grease, rust, or other contamination in accordance with accepted Army diving
cleaning procedures. Foreign substances within an assembly could result in equipment failure and
possible injury or death to personnel.
