Closure Plug · 1/2 in NPT · Weatherproof Gray · TayMac CP5050S
1/2 in NPT weatherproof closure plug for sealing unused threaded openings in cast or weatherproof boxes and covers. Gray metallic plug, commonly sold in boxes of 50, for outdoor and wet-location box assemblies where an unused hub needs to be closed.
What this product is for
This 1/2 in NPT closure plug is used to seal an unused threaded opening in a weatherproof or cast box, cover, or similar enclosure. It helps maintain the enclosure assembly when a hub or opening is not being used.
Use for
Use for 1/2 in NPT threaded openings in weatherproof boxes, cast device boxes, covers, and related fittings. Commonly used in outdoor branch circuit work, service areas, and light commercial installations where an unused opening must be closed.
Avoid for
Avoid using this plug in non-threaded openings or where a listed sealing method other than a threaded closure plug is required. Do not assume environmental performance beyond the box and cover assembly rating.
Best for
Best for electricians needing a simple threaded closure for unused 1/2 in hubs on weatherproof metallic boxes and covers. Suitable when matching a gray weatherproof box system.
Installed in
Typically installed in cast aluminium or metallic weatherproof boxes, covers, extension adapters, and similar enclosure accessories. Approximate plug face dimensions listed by distributors are about 0.81 in x 0.81 in (21 x 21 mm), with about 0.31 in depth (8 mm).
Why this product exists
Unused threaded openings can leave a box incomplete and exposed. This closure plug provides a matching threaded means to close the opening and finish the enclosure properly.
Compared with similar products
Compared with push-in or knockout seals, a threaded 1/2 in NPT closure plug is intended for threaded weatherproof openings. Compared with plastic alternatives, this model is listed by distributors as metallic and gray for use with matching weatherproof box systems.
