The IPEX 312pma is a Schedule 40 PVC male terminal adapter designed for use in conduit raceway systems. This fitting connects a PVC conduit run to an enclosure, panel, or junction box by threading into a female-threaded hub or knockout fitting. It is sized for 3.5-inch conduit and is manufactured from Schedule 40 PVC, making it suitable for both direct-burial and above-ground electrical installations. Electricians use this adapter to terminate conduit runs cleanly at equipment enclosures without the need for additional fittings. Its male-threaded end mates directly with standard female conduit hubs.
This adapter is used in residential, commercial, and light industrial electrical installations where PVC conduit systems are specified. Common applications include service entrance conduit terminations, panel feeder runs, and conduit terminations at junction boxes or meter enclosures. It is installed by licensed electricians working under NEC requirements and is appropriate for dry, damp, and wet location conduit systems where PVC is code-compliant.
Designed as an OEM-style replacement and standard fitting for Schedule 40 PVC conduit systems at 3.5-inch trade size.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits in the enclosure before making conduit terminations. Use PVC conduit cement rated for Schedule 40 fittings on the slip end; hand-tighten the male threads into the hub to avoid cross-threading or over-torquing the PVC threads. Confirm the fitting is fully seated and sealed before pulling conductors through the conduit run.
