Interconnecting Air-Supply Hoses
MSA air-supply hoses can be interconnected 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.
WARNING!
Do not use non-locking quick-disconnects to interconnect air-supply hoses. Use only the threaded connector (3/4-16 UNF) or
the locking-type quick-disconnects listed.
Failure to follow this warning can result in serious personal injury or death.
The CEJN chrome and SNAP-TITE/Parker locking quick disconnects shown below may be used to interconnect air supply
hoses. To connect, push the plug and socket together. To separate, the plug and socket must be pushed together and the
sleeve retracted from the plug.
