Appleton XJ1504 Explosion Proof Expansion Joint Coupling

Appleton XJ1504 Explosion-Proof Expansion Joint Coupling is a rigid expansion fitting for long runs of rigid metal conduit across structural expansion joints in hazardous locations, delivering up to 4 inches of movement without stressing the conduit. This 1-1/2 inch trade-size coupling measures 6-5/8 inches long with an outside diameter of 3-1/2 inches, and is manufactured from malleable iron with a hot-dipped galvanized finish to resist corrosion in challenging environments. It is UL 467 listed (UL file E14814) for explosion-protected service and is designed for use with rigid/IMC conduit, with compatibility for bonding jumper BJ41520 to maintain grounding continuity across joints. Part of the Appleton XJ expansion fittings family, XJ1504 provides concrete-tight, weatherproof performance between building sections, ensuring reliable electrical protection and code-compliant installation where expansion joints are present. These expansion couplings are intended to maintain electrical continuity and protect conduit runs in facilities with long, segmented construction, absorbing movement at joints while preserving a safe, grounded connection.
