Overview

ABB Installation Products T&B Series 3/8" Liquidtight Fitting (SKU: 5331SST6HT) is a corrosion-resistant stainless steel fitting designed for flexible metallic conduit in harsh environments. Constructed from type 316 stainless steel, this fitting resists corrosion from chlorides, chemicals, and moisture, making it ideal for coastal, chemical processing, food and beverage, pharmaceutical, and wastewater applications where traditional metallic fittings fail prematurely. The fitting features a durable Duraplated ground cone for secure grounding and electrical continuity, ensuring compliance with NEC and OSHA safety standards. With a temperature range of 0°C to 150°C, it handles high-heat environments such as industrial ovens, solar installations, and outdoor enclosures exposed to direct sunlight. High UV resistance prevents degradation from prolonged outdoor exposure, maintaining structural integrity and sealing performance. NEMA ratings of 3, 3R, 4, and 4X certify protection against windblown dust, rain, splashing water, and corrosion, suitable for both indoor and outdoor use. The fitting measures 1.64" (41.66mm) in length and 1.14" (28.96mm) in width, designed to fit 3/8" flexible metallic conduit. Its straight design simplifies installation in tight spaces while providing a secure, liquidtight seal. Unlike zinc-plated or aluminum fittings, this 316 stainless steel solution eliminates the need for frequent replacements in corrosive conditions, reducing maintenance costs and downtime. Trusted by engineers and contractors, ABB’s T&B Liquidtight Fittings deliver long-term reliability in critical infrastructure, ensuring electrical safety and system integrity.

How to Install the 5331SST6HT Liquid-Tight Flexible Metal Conduit Fitting

This guide provides step-by-step instructions for installing the 5331SST6HT stainless steel liquid-tight fitting onto flexible metallic conduit and securing it to an enclosure or box wall.

Estimated time: 15m

Tools needed:

Hacksaw, Standard screwdriver, Hammer, Torque wrench

Supplies needed:

5331SST6HT Liquid-Tight Fitting, Liquid-tight flexible metal conduit (LFMC), LNSS/038 Locknut (if using a knockout), 5261 Seal Gasket (if using a knockout)

  1. Prepare the Flexible Metal Conduit

    Cut the end of the flexible conduit with a clean, square cut. Use a metal jig, a sharp hacksaw with 32 teeth/inch, or a power band saw (24-32 teeth/inch, not more than 400 ft/minute). DO NOT use an abrasive wheel.

  2. Assemble the Fitting Components onto the Conduit

    Slide the gland nut onto the prepared end of the flexible metal conduit. Next, slide the nylon sealing ring onto the conduit, ensuring it is correctly oriented. Finally, thread the SAFE-EDGE® ground cone onto the conduit.

  3. Install the Fitting into the Enclosure

    Insert the assembled fitting into the desired opening in the box wall or enclosure. For knockout applications, place the 5261 seal gasket (if required for liquid-tight seal) and then thread the LNSS/038 locknut onto the fitting from the inside of the enclosure.

  4. Secure the Locknut (for Knockout Applications)

    If using a locknut for knockout applications, hand-tighten the LNSS/038 locknut and then further tighten it 1/4 turn using a hammer and a standard screwdriver, or an equivalent method. The recommended torque for the LNSS/038 locknut is 70 lb-in (7.9 N-m).

  5. Tighten the Gland Nut

    Tighten the gland nut to the UL recommended value to ensure a liquid-tight seal. For the 5331SST6HT fitting (3/8" NPT), the recommended tightening torque for the gland nut is 235 lb-in (26.6 N-m).
