Overview

The ABB XJG44-EMT is a 1-1/4" conduit expansion coupling engineered for Electrical Metallic Tubing (EMT) systems requiring thermal movement compensation. This coupling accommodates up to 4 inches of linear expansion and contraction, preventing conduit deformation in environments with significant temperature fluctuations. The integrated internal bonding jumper eliminates the need for external grounding straps, ensuring continuous electrical continuity while meeting NEC® Article 250.98 requirements for metallic conduit systems. The coupling features a tamper-proof design with a protected internal jumper, reducing labor time and material costs during installation. Constructed from zinc-plated malleable or ductile iron, the XJG44-EMT provides corrosion resistance and durability for both indoor and outdoor applications. Installation is simplified with no disassembly required—slide the fitting onto the conduit until it stops at the internal sliding bushing, tighten the gland nut for a raintight seal, and thread the next conduit length into place. Ideal for long conduit runs, risers, or areas exposed to thermal cycling, this coupling is a direct replacement for rigid or non-expansion couplings where movement compensation is necessary. The design includes a keyed internal sliding bushing for alignment and a bonding bushing to maintain system integrity.

How to Install the XJG-EMT Expansion Joint

This guide provides instructions for installing the XJG-EMT Expansion Joint with Electrical Metallic Tubing (EMT) to accommodate thermal expansion and contraction, ensuring a continuous electrical conductor and weatherproof seal.

Estimated time: 15m

Tools needed:

Pipe wrench

Supplies needed:

Electrical Metallic Tubing (EMT)

  1. Insert Electrical Metallic Tubing (EMT)

    Insert the Electrical Metallic Tubing (EMT) into each end of the pre-assembled XJG-EMT Expansion Joint. The gland nut is partially tightened from the factory to facilitate easy insertion of the tubing.

  2. Tighten Gland Nuts

    Using a pipe wrench, tighten the gland nut at the end of the EMT connector. Refer to the Torque Chart for correct torque values: 90.4 N•m (800 lbl-in) for 3/4” and smaller, 113 N•m (1000 lbl-in) for 1”, 1-1/4”, & 1-1/2”, and 181 N•m (1600 lbl-in) for 2” and larger. This action compresses the Teflon packing, creating a rain-tight seal.

  3. Position Internal Bushing

    Position the internal bushing in the middle of the expansion joint fitting to allow for equal movement (2 or 4 inches) in both directions from the center of the fitting. This ensures proper functionality for thermal expansion and contraction.
