SEPCO 706P Threaded Sealing Locknut, Zinc-Plated Steel Conduit Fitting

The SEPCO 706P Threaded Sealing Locknut is a zinc-plated steel locknut engineered to secure conduit fittings to enclosures, panels, and junction boxes in commercial and industrial electrical systems. This sealing locknut family is available in trade sizes from 1/2" through 4", giving contractors a full range of options to match conduit and enclosure openings across a job site. The zinc-plated steel construction resists corrosion for long-term reliability in demanding conditions, while the threaded sealing design creates a tight, secure connection at the conduit entry point. Built for electrical contractors and maintenance crews who need dependable, code-compliant conduit hardware, the 706P family complements standard conduit fittings, hubs, and connectors wherever a secure mechanical lock is required at the point of entry.

Key Features

  • Trade Size Range: Available in 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 2-1/2", 3", and 4" sizes to fit a wide range of conduit and enclosure openings.
  • Durable Construction: Zinc-plated steel body offers strength and corrosion resistance for demanding job-site environments.
  • Threaded Connection: Precision-threaded design engages securely with conduit and enclosure openings for a tight mechanical connection.
  • Sealing Locknut Design: Sealing-type construction helps resist moisture and debris intrusion at the conduit connection point.
  • Protective Finish: Zinc-plated finish helps guard against rust and wear over the life of the installation.
  • Secure Mechanical Lock: Threaded engagement holds conduit fittings firmly in place, helping maintain a stable connection over time.
  • Job-Site Ready: Steel construction is sized to work alongside standard rigid, IMC, and EMT conduit fitting hardware.

SEPCO SEP706P – Frequently Asked Questions

1) What trade sizes does the SEPCO 706P sealing locknut family cover?
The SEPCO sealing locknut family runs 1/2 inch through 4 inch trade sizes: 1/2 (706P), 3/4 (707P), 1 (708P), 1-1/4 (709P), 1-1/2 (710P), 2 (711P), 2-1/2 (712P), 3 (713P) and 4 inch (715P). Order by the trade size of the conduit or fitting thread, not the enclosure hole diameter.
2) Will a SEPCO sealing locknut work on rigid and IMC conduit, or only EMT fittings?
It is a threaded locknut, so it mates with threaded rigid and IMC conduit as well as the threaded shank of EMT connectors and hubs. The description states the steel body is sized to work alongside standard rigid, IMC and EMT conduit fitting hardware. What matters is that the mating part has a male thread of the same trade size.
3) Do I still need a sealing locknut if the enclosure is outdoors?
That is exactly what the sealing type is for. A plain steel locknut only provides mechanical grip; the SEPCO sealing locknut is built to resist moisture and debris intrusion at the conduit entry, which is why it gets specified on weather-exposed conduit runs and outdoor enclosures. It still does not replace a proper raintight hub where the installation calls for one.
4) Is the SEPCO sealing locknut steel or die-cast, and how does the finish hold up?
Steel body with a zinc-plated finish. Steel gives you more thread strength than a zinc die-cast nut when you are torquing a large fitting down, and the plating is the corrosion barrier for damp or industrial interiors. For continuous salt or chemical exposure most specs call for stainless or PVC-coated hardware instead.
5) Can I use these to standardize conduit entries across a building's panels and junction boxes?
Yes. The sealing locknut family covers 1/2 inch through 4 inch in one part series, so a maintenance or MRO stock of 706P through 715P handles nearly every conduit entry you will meet at panelboards, junction boxes and enclosures without mixing brands or finishes.
6) How many locknuts do I need per conduit entry?
Standard practice is two per threaded entry on a knockout or punched opening, one inside and one outside the enclosure wall, to bond and lock the fitting. If the enclosure has a threaded hub, one nut on the inside is typical. The SEPCO sealing locknut is a threaded nut, so count them the same way you would any locknut.
7) Is the 715P the same part as the 706P, just bigger?
Same SEPCO sealing locknut design, different trade size. 706P is the 1/2 inch and 715P is the 4 inch; everything between is one number per step up, and all of them share the zinc-plated steel construction and threaded sealing design.
