LIQUID-TIGHT FLEXIBLE METALLIC CONDUIT ( LFMC)

Product Introduction and Applications: 
Liquid-tight Flexible Steel Conduit is a raceway of circular cross section having an outer liquidtight, nonmetallic, sunlight-resistant jacket over an inner flexible metal core with associated couplings, connectors, and fittings for the installation of electric conductors. 
Liquidtight flexible metal conduit (LFMC) is intended for  use in wet locations or where exposed to mineral oil, both at a maximum temperature of 140°C.
LFMC shall be permitted to be used in exposed or concealed  locations as follows:
• Where conditions of installation, operation, or maintenance require flexibility or protection from liquids, vapors, or solids
• As permitted by 501.10(B), 502.10, 503.10, and 504.20 and in other hazardous (classified) locations where specifically approved, and by 553.7(B)
• For direct burial where listed and marked for the purpose
Features:
• Protection for wiring circuits located in extremely wet or damp areas
• Suitable for machines and equipment where ruggedness is required
• For use on presses, welders, pumps, blowers, grinders,conveyors, automated lines
• Galvanized steel core for mechanical protection
• Abrasion resistant PVC jacket won’t wrinkle or shrink from cut ends
• Exceptional crush proof quality
• Smooth interior for easy wire pull-through
• Complete protection against most liquids and moisture vapor
• Resists sunlight, heat, oil and chemical degradation 
• Rated: -20° C to +60° C (-5° F to +140° F)
• Accepts standard UL Listed liquid-tight connectors
• Superior protection for circuits located in hostile environments
• Installs quickly and easily from handy payout carton
