Southwire SIMpull™ NMLT Conduit

December 6, 2024

Type NM SIMpull™ NMLT is manufactured with rigid PVC reinforcement imbedded within a flexible PVC wall. The construction provides excellent impact and crush strength while remaining highly flexible. The conduit resists oils, mild acids and exposure to sunlight.

Construction

• A protective combination of thermoplastic materials formed into a conduit/raceway which seals out water, liquids, abrasives, alcohol, coolants, corrosive fumes and gases, dirt, grease, mineral acids, non-concentrated fixed alkalines, petroleum oils, salt air and spray, and weather
• Smooth interior for easy wire pulling
• UV sunlight resistant jacket
• Rated for temperature range of -30°C to 80°C , 60°C Oil (-22 to +176, 140°F Oil)
• Accepts standard liquid-tight fittings for use with LFNC-B
