The ATKORE 5140103 is a 0.5-inch EPVC male terminal adapter designed for use in electrical conduit systems. This fitting creates a threaded male connection at the terminal end of an EPVC conduit run, allowing the conduit to terminate cleanly into enclosures, junction boxes, or panel knockouts. It is manufactured from EPVC (encased PVC), a material suited for direct-burial and corrosive-environment electrical installations. Licensed electricians and electrical contractors install this type of fitting during conduit rough-in and termination work.
This terminal adapter is used in residential and commercial electrical installations where EPVC conduit systems are routed into enclosures or electrical panels. The 0.5-inch trade size makes it appropriate for smaller conduit runs carrying low-voltage or branch-circuit wiring. It is classified as an enclosure accessory and is a standard component in underground and embedded conduit applications where PVC-based systems are specified.
Designed as an OEM-style fitting for use with 0.5-inch EPVC conduit systems in standard electrical enclosure termination applications.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for conduit fittings and enclosure entries. De-energize all circuits in the affected panel or enclosure before making terminations. Use appropriate PVC conduit solvent cement on mating EPVC conduit ends per manufacturer and code requirements. Do not overtighten the threaded connection into enclosure knockouts, as EPVC fittings are not rated for the same torque as metallic fittings.
