B114T&B FIT TINGS INDUSTRIAL FIT TINGS—Liquidtight flexible metal conduit fittingsSpecificationsRef. CE Code Rule 12-1300Liquidtight flexible metal conduit is a raceway ofcircular cross section having an outer liquidtightnonmetallic, sunlight-resistant jacket over a flexiblemetal core.Liquidtight flexible metal conduit is permittedto be used for exposed or concealed work, in dry,damp or wet locations indoors and outdoors.Heavy-duty marked liquidtight flexible metalconduit is considered an acceptable wiring methodin hazardous location; namely Class 1 Div 2, ClassII &Class III.Liquidtight flexible metal conduit is not permittedwhere subjected to mechanical injury. Theconduit is not permitted to be used undergroundor embedded in cinder fill or concrete. It cannotbe used as a general purpose raceway.Use of liquidtight conduit is not permitted whereany combination of ambient or conductortemperature will produce temperature in excessof that for which the jacket is rated or in locationswhere flexing at low temperature will injure jacket.Liquidtight flexible metal conduit is not permittedfor conductors over 600 volts.Liquidtight flexible conduit is available in 3 8 in.through 6 in. trade size. Conduit is constructedwith galvanized steel, aluminum or stainless steelcore, regular or extra flex. Outer jacket is availablefor a variety of applications, e.g. oil resistant whereexposed to cutting oils and for service temperatureranging from -50 C to 150 C.Listed and certified conduit are constructed ofgalvanized steel core and thermoplastic jacketrated for maximum service temperature up to 75 Cand suitable for exposure to mineral oils but notto gasoline and similar solvents.Conduit is required to be supported adequately,and bending is restricted to 360 degrees total.Please refer to the following for further detailsand complete information:1.

Jacketshall be positively locked to core to preventsleeving. Where used as an equipment groundingconductor, the conduit shall conform toapplicable standards UL 360/CSA C22.2 No. 56. Flexible conduit when installed shall havesufficient slack to avoid sharp flexing andstraining due to vibration and thermal expansion/constriction. Conduit shall be installed in such amanner that liquids will tend to run off the surfaceinstead of draining toward the fittings. Where liquidtight flexible metal conduitterminates into a threaded or threadless opening,the conduit shall be assembled with approvedliquidtight fittings. Fittings used shall be reusabletype of malleable iron/steel construction, electrozinc plated inside and outside, furnished withnylon-insulated throat and taper-threaded hubas manufactured by ABB, series 5331.Approved fittings installed shall be:(1) Designed to prevent sleeving, assure plastic(raceway jacket) to plastic (gasket) seal.(2) Equipped with grounding device to assureground continuity irrespective of raceway coreconstruction. Grounding device if inserted intoraceway and directly in contact with conductorsshall have rolled over edges for sizes under5 inches.—01—02—05—06 At the point of flexing (i.e. where raceway leavesfitting), the thermoplastic raceway jacket shall notbe permitted to be in direct contact with metal. Where liquidtight flexible metal conduit isterminated into a threadless opening using athreaded hub fitting such as series 5331,a suitable moisture-resistant/oil-resistantsynthetic rubber gasket such as series 5262 shallbe provided between the outside of box orenclosure and fitting shoulder. Gasket shall beadequately protected by and permanentlybonded to a metallic retainer. Where liquidtight flexible metallic raceway isinstalled in outdoor or indoor locations andis exposed to environmental conditions thatare more than normally corrosive to exposedsurfaces, PVC-coated liquidtight flexible metalconduit fittings such as series 3321manufactured by ABB shall be used. Fittingsshall be coated with a nominal thickness of0.040 inches PVC and must meet the generalrequirements for liquidtight flexible metalconduit fittings indicated above. Liquidtight fittings required to couple threadedend of a fitting or pipe where rotation of fitting orpipe is limited or restricted shall be reusable typeof malleable iron/steel construction, electro-zincplated inside/outside with taper-threaded hub asmanufactured by ABB, series 41. Fittings shall beequipped with a moisture-resistant/oil-resistantsynthetic rubber gasket. Metal-to-metal seal ormetal-to-thermoplastic seal for this applicationshall be considered unacceptable.—03—04
