Duraflex® Type C-4 Pressure Tight Flexible Metal Conduit
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) Depending upon requirements, Duraflex product can be sold at cut or random lengths. (4) Working pressure ratings are based upon 70°F (21° C) and uniform pressure environments. (5) Working pressure characteristics will be reduced at higher temperatures. (6) Working pressures will vary based upon end connections. | |||||
