Emt Flex la400mr 4 in Liquidtight Flexible Metal Conduit

Product Description

The EMT FLEX la400mr is a 4-inch Type-UA/LA liquidtight flexible metallic conduit (LFMC) designed for wiring runs that require both mechanical protection and resistance to moisture, oils, and contaminants. The steel core provides structural integrity and crush resistance, while the gray PVC outer jacket seals the assembly against liquids. This conduit is sold cut to length, making it suitable for custom runs on jobsites where standard pre-cut sections are impractical. Licensed electricians install this product in commercial, industrial, and residential applications wherever flexible, liquidtight wiring protection is required by code.

Type-UA/LA liquidtight flexible metallic conduit is commonly used for final connections to motors, compressors, HVAC equipment, pumps, and other machinery where vibration isolation and moisture resistance are both required. The 4-inch trade size accommodates larger conductor bundles and is frequently specified in industrial and heavy commercial installations. Cut-to-length purchasing reduces waste and allows precise measurement before installation.

Key Features

• 4-inch trade size Type-UA/LA liquidtight flexible metallic conduit
• Steel core construction provides crush resistance and mechanical protection
• Gray PVC outer jacket seals against moisture, oils, and contaminants
• Sold cut to length for custom jobsite runs
• Suitable for use with standard LFMC fittings and connectors

Compatibility

Designed as an OEM-style replacement and standard-use flexible conduit for 4-inch trade size liquidtight metallic conduit fittings and connectors in commercial, industrial, and residential electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 350 governing liquidtight flexible metal conduit. De-energize all circuits completely before making connections to existing wiring systems. Use listed 4-inch LFMC fittings rated for the installation environment. Avoid sharp bends that exceed the conduit minimum bend radius, as this can damage the PVC jacket and compromise liquidtight integrity.
