Liquidtight Flexible Metal Conduit Fittings
Series 5331GR
External Bonding Liquidtight Flexible Metal Conduit Connectors
Application
• Used where external bonding jumper
is required around liquidtight flexible
metal conduit
• To positively bond conduit to box
or enclosure
• Used where flexible raceway is
installed in outdoor or indoors
location where exposed to
continuous or intermittent moisture
Features
• Designed with provision to install
bonding jumper in several positions
• Designed to accept mechanical
or compression lug
• Ability to install quickly with low
torque effort
(1) Compressed metallic convolutions;
assures ground contact with low
impedance and high raceway
holding power (A)
(2) Single helical thread on ground cone
is easy to install without cross thread;
accepts variations in raceway diameters
and convolution pitch (B)
(3) Rolled over edge protects conductors (C)
• Sealing ring design has following
exclusive features:
(1) Grips and seals at leading and trailing
edge — will not abrade raceway
jacket (D)
(2) Provided with grooves on inside
diameter for anti-sleeving (E)
(3) Shoulders on both ends for extra
sealing (F)
(4) Symmetrical shape ensures
foolproof assembly
• Can be disconnected and reuse
• Watertight/oil tight installation at
box or enclosure termination is
ensured by:
(1) External taper thread hub on 5331GR
series and use of sealing gasket 5262
series (G)
(2) Taper tapped hole on 5271 series
• Suitable for use in Class I Division 2,
Class II Division 1 & 2 and Class III
Division 1 & 2 Hazardous Locations
per NEC Article 500
• Suitable as a bonding means per
UL 467 and NEC Article 351-9
• Conforms with JIC requirements
