New Drink Tube
new CAM (chemical agent monitor) is being fielded. It’s called ICAM
(improved chemical agent monitor) and it’s a bit different from its ancestor. But,
there are a few things you need to remember about both CAMs. The ICAM,
NSN 6665-01-357-8502, is more reliable and needs less maintenance.
CAM and ICAM
Run it
—If you run both CAMs for 30 minutes
every
week, you’ll prevent 95
percent of all CAM problems. But don’t use expensive lithium batteries to
operate it in the NBC room or during training. Instead, order the BAT (battery

—The ICAM has its own TMs:
TM 3-6665-343-10 and -23&P. If they
don’t come with your ICAMs, have

here are two M40/M42 mask drink
tubes in the field, NBC NCOs, and
you need to know which one you’ve
got.
The new drink tube looks like a
stretched Z—it has two bends. The old
tube has only one bend.
The new drink tube, NSN 4240-01-
441-0557, can be used only with the
new drink tube coupling, NSN 4240-
01-462-0045. If the new tube disap-
pears or if the coupling is damaged,
you can replace them with the proce-
dures that begin on Page 2-54 of TM
3-4240-346-20&P. The new drink tube
and coupling NSNs will be added to
the TM in the next change.
If the old drink tube coupling is dam-
aged, you must turn in the facepiece
for depot repair.
Do not try to use the old drink tube
with the new coupling or visa versa.
That puts the drink tube in the wrong
position for drinking. The old coupling
has a squared base and points upward
toward the front voicemitter and nose-
cup ridge. The new coupling is straight
and points out of the facepiece.
