SEPCO P3 – Frequently Asked Questions

1) What is the Sepco P3 slotted plug used for?
The Sepco P3 is a threaded plug that closes off unused openings on conduit bodies, boxes, and electrical fittings. It threads into the opening and seals it against dust, debris, and moisture while a job is staged or a system is being reconfigured. The head is slotted, so a standard flat-blade screwdriver drives it in or backs it out.
2) Is the Sepco P3 plug steel or zinc, and will it hold up outdoors?
It is die cast zinc. Zinc gives corrosion resistance without a plated coating that can be scratched off, which is why these plugs survive jobsite handling and long service in damp or dirty electrical environments. For strongly corrosive or chemical exposure, specify a plug material rated for that environment instead.
3) Can I use a slotted plug instead of a hex head or square head conduit plug?
Functionally they seal the same opening; the difference is the driver. The P3 slotted head takes a flat-blade screwdriver, which is faster in tight conduit bodies and on an electrician's belt. A hex or square head plug accepts a wrench, so it can be torqued harder, which matters when you want a tighter seal or a plug that resists being backed out. For routine sealing of unused hubs and knockouts on conduit bodies and enclosures, the slotted P3 is the quicker choice.
4) How do I order the Sepco P3 plug, and what is the part number?
The Sepco part number is P3. It is ordered by model as a single item, so specify the trade size you need for the hub or opening being closed.
5) Can I standardize on one plug across panelboards, enclosures, and conduit bodies in my facility?
Yes, within a given trade size. The P3 is used for conduit body and fitting openings, unused knockouts and threaded hubs, and panelboard and enclosure servicing, so an MRO crew can stock it in the sizes their raceway system uses rather than carrying separate plugs per application. Stock by trade size, since each size only threads its matching opening.
6) Will the P3 plug sit flush or stick out of the fitting?
Low profile. The P3 is a compact plug that sits flush against the fitting once threaded home, so it does not snag or protrude where conduit bodies run close to a wall, ceiling, or adjacent raceway.
