UL Certifies Heavyduty Steel Conduit for Industrial Safety

In demanding industrial environments, protecting electrical wiring from moisture, oil, and physical damage is paramount. Engineers and electricians often face the challenge of finding conduit that combines rugged durability with high flexibility.

The 1-1/4-inch heavy-duty steel flexible conduit, dual-certified by Underwriters Laboratories (UL) and the Canadian Standards Association (CSA), emerges as the ideal solution. Featuring a resilient steel core structure sheathed in oil- and moisture-resistant PVC (polyvinyl chloride), this conduit delivers exceptional mechanical protection and environmental isolation. Its liquid-tight design effectively prevents fluid ingress, ensuring electrical system safety in wet or oily conditions. Whether for exposed installations or concealed wiring spaces, this conduit meets the rigorous demands of heavy-duty applications.

This conduit's primary strengths lie in its superior protective capabilities and broad applicability. The sturdy steel core provides outstanding resistance to compression, tension, and torsion, enabling it to withstand various mechanical stresses in industrial settings. The external PVC jacket not only serves as an effective barrier against moisture and oil but also offers excellent abrasion and chemical corrosion resistance, significantly extending the conduit's service life.

The conduit's design prioritizes installation convenience and flexibility. Its pliable structure allows easy bending to accommodate complex routing layouts, minimizing cutting and connection work during installation. The integrated bonding strip design simplifies grounding connections, enhancing electrical system safety.

With its exceptional protective performance, the 1-1/4-inch heavy-duty steel flexible conduit finds wide use in various industrial and commercial settings, including:

• Manufacturing Facilities: Safeguarding electrical wiring in machinery and production lines from oil, metal shavings, and humidity.
• Outdoor Installations: Providing reliable protection for electrical systems exposed to rain, moisture, or corrosive substances.
• Commercial Buildings: Serving areas requiring high-strength, durable electrical protection such as data centers and laboratories.
• Public Transit Systems: Ensuring secure signal and power transmission in damp, high-impact environments like subways and tunnels.

• Inner Diameter: 1-1/4 inches (approximately 31.75 mm)
• Outer Diameter: Varies by specific product model (typically slightly larger than nominal inner diameter)
• Material: Steel core with PVC outer jacket
• Color: Gray
• Length: 50 feet (approximately 15.24 meters) standard coil packaging
• Type: UA (denoting heavy-duty liquid-tight flexible steel conduit)
• Certifications: UL, CSA
• Features: Liquid-tight, heavy-duty, integrated bonding strip

In industry parlance, this product may also be identified by various manufacturer-specific codes such as 980050023719, 114LTULX50, or LFMC (Liquidtight Flexible Metal Conduit). Familiarity with these alternate designations facilitates accurate product identification during procurement and technical discussions.

The 1-1/4-inch heavy-duty steel flexible conduit stands as an essential component in industrial electrical installations, offering unmatched protective performance, rigorous safety certifications, and flexible installation characteristics to ensure long-term reliability for electrical systems in even the most challenging environments.
