Application:

EC couplings are used:
ɀ in hazardous areas where a
flexible member is required in a
conduit system to accomplish
difficult bends, or to allow for
movement or vibration of
connected equipment or units

Features:

ɀ Rugged design to withstand
explosive pressure (Class I)

ɀ Mechanical abuse
ɀ Liquid-tight for wet locations
ɀ For use where lack of space

makes use of rigid conduit
difficult
ɀ Wire duct liner in sizes
