PVC Male Terminal Adapter · 1-1/4 in Trade Size · Threaded Male End for Box Connection · Westlake Pipe & Fittings RTA25
What this product is for
This PVC male terminal adapter is used to terminate 1-1/4 in rigid PVC conduit into an enclosure, box, or other threaded entry point. It provides a solvent-weld socket on one side and a tapered male threaded end on the other for a secure transition from conduit to equipment.
Use for
Use for rigid PVC conduit runs where you need to enter panels, junction boxes, pull boxes, meter bases, or other electrical enclosures. It is commonly selected for outdoor and indoor raceway systems where non-metallic conduit is specified.
Avoid for
Avoid using this fitting where a different conduit system or fitting type is required, such as EMT, ENT, or direct threaded metallic raceway connections without the proper transition components. Do not treat this fitting as a pressure plumbing fitting.
Best for
Best for electricians and contractors installing 1-1/4 in PVC conduit where a clean box termination is needed. It is a practical choice for service, commercial, utility, and industrial conduit work using standard rigid PVC fittings.
Installed in
Typically installed in electrical rooms, service entrances, exterior wall penetrations, utility connections, and exposed or concealed PVC conduit systems. The 1-1/4 in trade size is commonly used where larger conductor fills or feeder raceways are required.
Why this product exists
This fitting exists to connect solvent-weld PVC conduit to equipment with a male threaded termination. It simplifies box entry while maintaining compatibility with standard rigid PVC conduit systems.
Compared with similar products
Compared with a PVC coupling, this adapter adds a male threaded termination for enclosure entry. Compared with metallic adapters, it is intended for non-metallic rigid PVC conduit systems. As a typical conduit fill rule of thumb, 1-1/4 in raceway is chosen when conductor count or wire size exceeds what smaller conduit can handle, but actual fill must be confirmed to code and conductor type. Actual performance depends on installation conditions, conductor type, layout, and local electrical code.
