The ATKORE 6141633 is a 5-inch EPVC (encased polyvinyl chloride) conduit coupling designed to join two sections of EPVC conduit in a continuous, protected raceway. EPVC couplings are specified where conduit must be encased in concrete or buried underground, providing a secure, solvent-weld joint that resists moisture, soil chemicals, and mechanical stress. This fitting is installed by licensed electricians on commercial and industrial projects where code requires encased conduit systems.
This coupling is used in underground electrical distribution systems, duct bank installations, and direct-burial applications where EPVC conduit is specified. It is suited for commercial construction, utility infrastructure, and industrial site work requiring large-diameter conduit runs. The 5-inch trade size accommodates high-capacity feeder and service conductor installations.
Designed as an OEM-style fitting for use with 5-inch EPVC conduit systems in underground and concrete-encased electrical raceway applications.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for underground and encased conduit systems. De-energize all circuits in the raceway before working on any connected conduit run. Clean pipe ends and apply listed EPVC solvent cement per manufacturer instructions before joining. Do not use standard PVC cement in place of EPVC-rated solvent cement, as material compatibility is required for listed performance.
