SEPCO NTC-100 Series Malleable Iron Compression Conduit Connector

SEPCO's NTC-100 Series Compression Conduit Connector is a malleable iron fitting engineered to join conduit sections with a secure, mechanically sound compression connection within conduit and raceway systems. It is available across the full NTC-100 lineup in trade sizes ranging from 1/2" through 4", giving electrical contractors and maintenance teams a dependable coupling point sized to match nearly any commercial or industrial conduit run. Its malleable iron body offers greater durability and corrosion resistance than lighter-gauge stamped steel alternatives, helping every size in the range withstand demanding jobsite handling, moisture exposure, and everyday wear.

  • Malleable Iron Construction: A rugged fitting body resists impact, cracking, and corrosion better than lightweight stamped steel, extending service life in demanding jobsite conditions.
  • Compression-Style Connection: Mechanically compresses around the conduit to form a tight, secure joint, providing a reliable mechanical connection point within the raceway system.
  • NTC-100 Series: Identifies this connector within the SEPCO NTC series of compression fittings engineered for conduit and raceway applications.
  • Simplified Installation: The compression design allows electricians to make up a solid connection efficiently, helping reduce installation time on the jobsite.

SEPCO NTC-50 – Frequently Asked Questions

1) What trade sizes does the SEPCO NTC-100 Series compression conduit connector come in?
Nine trade sizes cover the range: 1/2, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3 and 4 inch. The part number tracks the size, so a 1/2 inch is NTC-50, a 3/4 inch is NTC-75, a 1 inch is NTC-100, and it runs up through NTC-400 for the 4 inch. Order by the conduit trade size you are terminating, not by the outside diameter of the tubing.
2) Is the NTC-100 a set-screw or compression fitting, and does that matter for my install?
It is a compression fitting. The gland nut squeezes a ring around the conduit, which makes it up tighter and more resistant to pull-out and moisture entry than a set-screw connector. Practical difference on the job: you need a wrench on the nut rather than a screwdriver, and the conduit has to be cut square and reamed so it seats fully before you tighten.
3) Can I use the SEPCO NTC connector to land conduit on a panel or junction box?
Yes. It is a connector, not a coupling, so one end compresses onto the conduit and the threaded end passes through the knockout and is secured with a locknut inside the enclosure. Match the trade size to the knockout: a 3/4 inch knockout takes the NTC-75. Panel and enclosure terminations are one of the listed applications for the series.
4) Why choose a malleable iron connector over a die-cast or stamped steel one?
Malleable iron is the body material on the NTC series, and it takes impact and handling abuse without cracking the way zinc die-cast can, and it holds up better to moisture and corrosion than lighter stamped steel. On industrial runs, loading docks, plant floors and anywhere fittings get stepped on or knocked by equipment, that is the reason to spend on iron.
5) Will a compression connector work for a retrofit where I cannot rotate the existing conduit?
That is exactly where compression fittings earn their place. Because nothing threads onto the conduit itself, you slide the body over a cut end and tighten the nut, so the run can stay fixed in the hangers. Renovation and retrofit electrical work is a stated application for the NTC series, across every size from 1/2 up to 4 inch.
6) What is the exact part number for a 2 inch SEPCO compression conduit connector?
NTC-200 is the 2 inch. The neighbouring sizes are NTC-150 for 1-1/2 inch, NTC-250 for 2-1/2 inch and NTC-300 for 3 inch, so if you are ordering a mixed pull, the number follows the size in hundredths of an inch.
