EMT/Rigid Conduit, Liquatite Flexible Raceway, Killark Explosion-Proof Fittings & Industrial Wire
Complete raceway and conductor staging for mechanical rooms, wastewater treatment plants, chemical/lab hoods, and factory machinery drops across the Merrimack Valley, Greater Boston, and Southern New Hampshire.
Industrial Raceway, Liquidtight Whip & Hazardous-Location Fitting Specialists
Industrial environments in New England—from municipal wastewater aeration basins and boiler rooms to food-processing washdown lines and university solvent storage rooms—rapidly destroy standard commercial die-cast fittings. Specifying the wrong flexible conduit jacket or omitting an explosion-proof EYS conduit seal can cause premature insulation breakdown or failed electrical inspections.
Frank P. McCartin Co., Inc. stocks genuine Electri-Flex Liquatite flexible metal and non-metallic conduit alongside heavy-duty malleable iron, copper-free aluminum, and stainless fittings from Crouse-Hinds, Killark, O-Z/Gedney, Steel City, Raco, and Arlington. Our counter cuts portable SOOW cord, multi-conductor control cable, and feeder wire to length for immediate jobsite pickup.

Counter Q&A: Conduit, Liquatite, Killark & Wire/Cable
What is the difference between Liquatite Type LA and Type LT flexible conduit?
Electri-Flex Liquatite Type LA is UL 360 and CSA certified, features a heavier crush-resistant steel strip, and incorporates a built-in continuous copper bonding strip in sizes 3/8" through 1-1/4" for equipment grounding compliance under NEC 350.60. Type LT is a general-purpose oil-resistant flexible metal conduit without the integral copper bonding strip.
