The IPEX 400ppl is a 4-inch PVC conduit plug designed to seal the open end of Schedule 40 or Schedule 80 PVC conduit during installation, storage, or when a conduit run is temporarily out of service. Constructed from PVC, it provides a secure, moisture-resistant barrier that keeps debris, insects, and water out of the conduit system. Electricians and electrical contractors install this plug on exposed conduit ends in residential, commercial, and industrial applications where conduit protection is required before or after wire pull.
This conduit plug fits 4-inch PVC conduit systems and is suited for use in exposed or concealed electrical raceways. It is commonly used on job sites to protect conduit ends during rough-in phases and on installed conduit that remains unused or capped off. The PVC construction makes it appropriate for both indoor and outdoor environments where corrosion resistance is a priority.
Designed as an OEM-style replacement and standard fitting for 4-inch PVC electrical conduit systems.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize any circuits associated with the conduit before handling open conduit ends. The plug is typically pressed or threaded onto the conduit end by hand; ensure the conduit end is clean and free of burrs before seating the plug. Do not use this plug as a permanent pressure-rated fitting.
