SEPCO NTCC Series Compression Conduit Coupling, Malleable Iron

The SEPCO NTCC Series Compression Conduit Coupling joins sections of electrical conduit into a continuous, secure raceway for commercial and industrial installations, and is available across trade sizes from 1/2" to 4" to cover a full range of conduit runs. Built from malleable iron, this compression-style coupling delivers the strength and rigidity electrical contractors rely on, while the tool-tightened compression connection creates a firm joint without threading. Whether you need a 1/2" coupling for a branch circuit or a 4" coupling for a larger feeder run, the NTCC Series gives contractors a consistent, code-compliant coupling option across the entire size range.

Key Features

  • Trade Size Range: Available in trade sizes from 1/2" to 4" to fit a wide range of conduit runs on a single, consistent platform.
  • Durable Construction: Made from malleable iron for excellent strength, rigidity, and long-term durability in conduit and raceway systems.
  • Compression Connection: A tool-tightened compression joint secures conduit ends firmly without requiring threading, saving setup time in the field.
  • Continuous Raceway: Joins conduit sections end-to-end to maintain a secure, uninterrupted electrical raceway from point to point.
  • Field-Ready Design: Streamlines rough-in installation and reduces labor time on commercial and industrial jobsites where speed and reliability matter.
  • NTCC Series: Part of SEPCO's NTCC Series of malleable iron compression conduit couplings, offering a consistent fit across the full 1/2" to 4" size range.
  • Rigid Assembly: Malleable iron construction resists deformation and maintains a tight mechanical connection under everyday jobsite handling and conditions.
  • Contractor-Grade Fitting: Suited for electrical contractors, maintenance crews, and MRO supply stock that need a dependable compression coupling on hand in multiple sizes.

SEPCO NTCC-50 – Frequently Asked Questions

1) What trade sizes does the SEPCO NTCC coupling come in?
Nine trade sizes, covering 1/2, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3 and 4 inch conduit. Part numbers follow the size: NTCC-50 for 1/2 inch, NTCC-75 for 3/4, NTCC-100 through NTCC-400 for the larger sizes. Order by the trade size of the conduit you are joining, not the outside diameter.
2) Do I have to thread the conduit to use an NTCC coupling?
No threading needed. The NTCC is a compression coupling, so the conduit end goes in as cut and the joint is made by tightening the compression nut with a wrench. That makes it useful on cut lengths in the field where running a threader is not practical.
3) Can I use a compression coupling to join two pieces of conduit already fixed in place?
A compression coupling like the NTCC is the right choice there. Because neither conduit end has to rotate, you can slide the coupling over a cut end and tighten it, which a threaded coupling cannot do between two fixed runs. For that reason it is commonly used on repairs and extensions of existing raceway as well as new rough-in.
4) What is the difference between the SEPCO NTCC compression coupling and the nVent CADDY ERC 2G9S10WB twist coupling?
Both join metallic conduit, but they make the joint in different ways. The SEPCO NTCC is a compression coupling in malleable iron, tightened with a tool onto the conduit ends, and it is offered in trade sizes from 1/2 inch through 4 inch. The nVent CADDY 2G9S10WB is an ERC series twist coupling for metallic conduit, which is made up by twisting rather than by a tool-tightened compression body. If the spec on the drawing calls out a compression fitting, the NTCC is the one that matches; if the crew is standardizing on CADDY ERC twist fittings, the 2G9S10WB stays in that system.
5) Will a 1/2 inch NTCC coupling work for a branch circuit run and a 4 inch for a feeder?
Yes, and that is the point of the range. NTCC-50 handles 1/2 inch branch-circuit conduit; NTCC-400 handles 4 inch feeder conduit. The same compression design and malleable iron body run through every size, so a contractor can standardize on one series across a whole job instead of mixing coupling types by size.
6) I need a conduit coupling in a 3 inch or 4 inch trade size - does the nVent CADDY ERC twist coupling cover that?
For the larger feeder sizes, go with the SEPCO NTCC series, which runs the full 1/2 inch through 4 inch trade size range on one malleable iron platform, including NTCC-300 for 3 inch and NTCC-400 for 4 inch. The nVent CADDY 2G9S10WB is a single ERC series twist coupling rather than a full size ladder, so for a mixed run where you need one coupling type from branch circuit up to a 4 inch feeder, the NTCC keeps the fitting consistent end to end.
7) Do I need one NTCC coupling per joint, or does it come with anything else?
One coupling makes one conduit-to-conduit joint, and each is ordered individually by trade size. Nothing else is required to make the joint up, since the compression connection is integral. Buy quantity to match your number of splices, and match every coupling to the conduit trade size it lands on.
