T&B Fittings Industrial Fittings Liquidtight Flexible Metal Conduit Fittings Specifications Ref. CEC Rule 12-1300 Liquidtight flexible metal conduit is a raceway of circular cross section having an outer liquidtight nonmetallic, sunlight resistant jacket over a flexible metal core. Liquidtight flexible metal conduit is permitted to be used for exposed or concealed work, in dry, damp or wet locations indoors and outdoors. With the exception of Class I Division I locations, liquidtight flexible metal conduit is considered an acceptable wiring method in hazardous locations Class 1 Division 2 (CECRule J18-152(6)). Liquidtight flexible metal conduit is not permitted where subjected to mechanical injury. The conduit is not permitted to be used underground or embedded in cinder fill or concrete. It cannot be used as a general purpose raceway. Use of liquidtight conduit is not permitted where any combination of ambient or conductor temperature will produce temperature in excess of that for which the jacket is rated or in locations where flexing at low temperature will injure jacket. Liquidtight flexible metal conduit is not permitted for conductors over 600 volts. Liquidtight flexible conduit is available in 3/8 in. through 6 in. trade size. Conduit is constructed with galvanized steel or aluminum core, regular or extra flex. Outer jacket is available for a variety of applications, e.g. oil resistant where exposed to cutting oils and for service temperature ranging from -50C to 150C. Listed and certified conduits are constructed of galvanized steel core and thermoplastic jacket rated for maximum service temperature of 60C and suitable for exposure to mineral oils but not to gasoline and similar solvents. Conduit is required to be supported adequately, and bending is restricted to 360 degrees total.

B84 w w w.t nb.c a T&B Fittings Industrial Fittings Liquidtight Flexible Metal Conduit Fittings Suggested Specifications for Liquidtight Flexible Metal Conduit Fittings *Liquidtight Flexible Metal conduit used shall be of the type with galvanized steel core inside and outside and outer thermoplastic jacket suitable for the ambient environmental conditions. Jacket shall be positively locked to core to prevent sleeving. Where used as an equipment grounding conductor, the conduit shall conform to applicable standards UL 360/CSA C22.2 No. 56. * Flexible conduit when installed shall have sufficient slack to avoid sharp flexing and straining due to vibration and thermal expansion/ constriction. Conduit shall be installed in such a manner that liquids will tend to run off the surface instead of draining toward the fittings. *Where liquidtight flexible metal conduit terminates into a threaded or threadless opening, the conduit shall be assembled with approved liquidtight fittings. Fittings used shall be reusable type of malleable iron/steel construction, electro-zinc plated inside and outside, furnished with nylon insulated throat and taper threaded hub as manufactured by Thomas & Betts, Series 5331. (2) E quipped with grounding device to assure ground continuity irrespective of raceway core construction. Grouning device if inserted into raceway and directly in contact with conductors shall have rolled over edges for sizes under 5 inches. At the point of flexing (i.e. where raceway leaves fitting) the thermoplastic raceway jacket shall not be permitted to be in direct contact with metal. *Where liquidtight flexible metal conduit is terminated into a threadless opening using a threaded hub fitting such as Thomas & Betts Series 5331, a suitable moisture resistant/oil resistant synthetic rubber gasket such as Thomas & Betts Series 5262 shall be provided between the outside of box or enclosure and fitting shoulder. Gasket shall be adequately protected by and permanently bonded to a metallic retainer. (1) D esigned to prevent sleeving, assure plastic (raceway jacket) to plastic (gasket) seal. *Where liquidtight flexible metallic raceway is installed in outdoor or indoor locations and is exposed to environmental conditions that are more than normally corrosive to exposed surfaces, PVC coated liquidtight flexible metal conduit fittings such as Series 3321 manufactured by Thomas & Betts shall be used.

A Until now, there's been no ideal conduit fitting solution for use in heavily corrosive environments. Traditional metallic fittings corrode and require frequent replacement. nonmetallic fittings offer less strength, lower UV-resistance, and don't stand up well in extreme temperatures. T&B Stainless Steel Liquidtight Conduit Connectors are constructed of 304 stainless steel to resist corrosion while offering high strength, high UV-resistance, and high endurance. Choose among a full range of fittings in straight, 45, and 90 angled configurations for 3/8 in. to 2 in. conduit sizes.
