The IPEX 500pma is a 5-inch PVC Schedule 40 conduit male terminal adapter designed to transition from rigid PVC conduit to an enclosure, panel, or junction box knockout. This fitting threads into a standard female hub or locknut assembly, creating a secure, weatherproof entry point. Built from Schedule 40 PVC, it delivers solid chemical and corrosion resistance in both indoor and outdoor electrical installations. Licensed electricians and electrical contractors handle this fitting as part of larger conduit system builds and service work.
This terminal adapter is used in residential, commercial, and light industrial electrical installations where PVC conduit terminates at an enclosure, meter base, panel cabinet, or other electrical housing. It is suited for direct-burial-adjacent installations and above-grade conduit runs where PVC material is the system standard. The 5-inch size accommodates large-diameter conduit runs typical in main service entry, industrial feeder, or high-capacity branch circuit applications.
Designed as an OEM-style replacement and standard fitting for 5-inch Schedule 40 PVC electrical conduit systems.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits in the affected conduit system before making connections at enclosures or panels. Use appropriate PVC conduit cement and primer when joining this adapter to conduit, following the cement manufacturer's cure time before pulling wire. Do not over-torque threaded connections into enclosure knockouts, as PVC threads can crack under excessive force.
