Duraflex® C-4 is an extremely flexible, convoluted, pressure tight metal conduit which exhibits prolonged resistance to vibration, heat, and pressure

Features:
The brass innercore is overbraided with one layer of 1 over 1 under flat bronze wire and a second layer of 2 over 2 under fine bronze wire.

Application:
Industrial Gas Turbine Engines, Electrical Wiring Protection, Abrasion Resistance, Non-Sparking, and Electrical Continuity.

Construction:
Innercore -Brass; Braid - 2 Layers
1st Layer Bronze Flat Wire (1 over x 1 under), 2nd Layer Bronze Fine Wire (2 over x 2 under)

Fittings:
Customers may specify from a wide range of fittings to satisfy electromagnetic hermetic sealing, high temperature, self-locking, or other requirements. Typically, end fittings for industrial applications are made of brass; however, more severe operating environments may call for fittings constructed of other materials.

 (1) * denotes special size
 (2) Run lengths over 25 feet are special order
 (3) Working pressure ratings are based upon 70°F (21° C) and uniform pressure environments.
 (4) Working pressure characteristics will be reduced at higher temperatures.
 (5) Working pressures will vary based upon end connections.
