The IPEX 400pfa is a 4-inch PVC Schedule 40 conduit female adapter designed to connect rigid PVC conduit runs to threaded fittings, enclosures, or junction boxes. Built from Schedule 40 PVC, this adapter provides a durable, corrosion-resistant transition point in electrical raceway systems. It is installed by licensed electricians working on residential, commercial, and light industrial conduit installations. The female-threaded socket end accepts standard threaded male conduit or fittings, making it a common component when terminating conduit at panels, pull boxes, and equipment enclosures.
This adapter is suited for use in underground, direct-burial, and above-grade PVC conduit systems where a female-threaded transition is required. It fits standard 4-inch Schedule 40 PVC conduit and is commonly installed when terminating runs at electrical enclosures, meter bases, or at the transition between rigid conduit sections and threaded entry points. Its non-metallic construction makes it appropriate for wet locations and corrosive environments where metal fittings would be prone to degradation.
Designed as an OEM-style replacement and standard-fit component for 4-inch Schedule 40 PVC electrical conduit systems.
Installation is performed by a licensed electrician in accordance with NEC requirements for PVC conduit systems. Solvent-cement the conduit end into the fitting socket using a PVC conduit cement rated for the application; do not use plumbing-grade cement. De-energize all circuits and follow lockout/tagout procedures before working inside any enclosure where this fitting terminates. Ensure all threads are clean and fully engaged before securing the fitting to the enclosure or box.
