INTERCONNECTING AIR-SUPPLY
HOSES
MSA air-supply hoses can be inter-
connected up to a maximum length of
300 feet without voiding the NIOSH
approval of the device. MSA offers
both threaded and locking-type quick-
disconnects to interconnect hoses.
The following threaded connector
assembly can be used to interconnect
sections of approved air-supply hose.
Check all hose connections to be
sure fittings are secure. This must
be done to ensure a continuous
flow of air. Failure to follow this pre-
caution can result in serious per-
sonal injury or death.
Do not use non-locking quick-dis-
connects to interconnect air-supply
hoses. Use only the threaded con-
nector (3/4-16 UNF) or the locking-
type quick-disconnects listed.
The CEJN chrome and SNAP-TITE
locking quick-disconnects shown
below may be used to interconnect
air-supply hoses. To connect, push
the plug and socket together. To sep-
arate, the plug and socket must be
pushed together and the sleeve
retracted from the plug.

QUICK-DISCONNECTS
Various quick-disconnect assemblies
that can be used with the system are
shown below. Quick-disconnects are
required to connect air-supply hoses
to the respirator. Additionally, locking-
type quick-disconnects can be used
to interconnect lengths of MSA air-
supply hose. Air-supply hoses can be
interconnected up to a maximum
length of 300 feet. Up to 12 sections
of hose can be used to make up the
maximum working length of hose.
Locking quick-disconnects easily con-
nect by pushing the plug and socket
together. To separate, the plug and
socket must first be pushed together
then the sleeve retraced from the
plug.
