SEPCO QL-50D Zinc-Plated Steel Quicklock Insulated Duplex Flex Connector

The SEPCO QL-50D is a zinc-plated tubular steel Flex Connector engineered for connecting 1/2-Inch flexible conduit to boxes, panels, and enclosures in commercial and industrial electrical systems. Featuring a quicklock connection style and insulated-type construction, this duplex connector is built for electricians who need a dependable, corrosion-resistant fitting that goes in fast and stays secure through the life of the installation. Whether used on new construction or renovation work, the QL-50D is sized specifically for 1/2-Inch flexible conduit runs and configured in SEPCO's duplex style for this model.

Key Features

  • 1/2-Inch Trade Size: Sized to fit 1/2-Inch flexible conduit, making it a direct match for standard flex runs into junction boxes, panels, and enclosures.
  • Zinc-Plated Tubular Steel Construction: The connector body is fabricated from zinc-plated tubular steel, combining mechanical strength with corrosion resistance for a long service life in the field.
  • Quicklock Connection Style: The quicklock design is built for fast, secure engagement with flexible conduit, helping installers move through repetitive connector installations efficiently on rough-in day.
  • Insulated Type Design: An insulated-type throat helps guard conductor insulation as wires are pulled through the connector during rough-in and finish wiring.
  • Duplex Configuration: The QL-50D is manufactured in SEPCO's duplex configuration, the specific connector style designated for this model number.
  • Purpose-Built Flex Connector: Designed specifically as a flexible conduit connector, the QL-50D is intended for use wherever flexible metal conduit terminates at a box, panel, or enclosure.

SEPCO QL-50D – Frequently Asked Questions

1) What does the "duplex" in the SEPCO QL-50D mean?
Duplex is the connector configuration SEPCO builds this model in - a two-conduit style fitting rather than a single. If you need one flex per knockout, order a single-configuration connector instead; the QL-50D is only made in the duplex style.
2) Can I use the SEPCO QL-50D on AC or MC cable as well as flexible metal conduit?
It is catalogued as an AC/MC/flex connector and the stated application is flexible metal conduit (FMC) terminating at a box, panel, or enclosure, in 1/2 inch size. Match the cable or conduit to the 1/2 inch trade size and the duplex style before ordering.
3) Is the QL-50D flex connector insulated for pulling conductors?
Yes - it is an insulated-type connector, with the throat insulated so conductor insulation isn't chewed up as wire is pulled through during rough-in and finish wiring. That is what inspectors look for where flex terminates at a panel.
4) How does a Quicklock flex connector differ from a squeeze or set-screw connector?
Quicklock is the connection style on the QL-50D: the conduit pushes in and locks, so there is no screw to drive on every fitting. On a rough-in with dozens of terminations that saves real time. Squeeze and set-screw connectors need a tool at each fitting, which some specs or inspectors still call for - check the drawing before you substitute.
5) Will a zinc-plated steel flex connector hold up in a damp or industrial space?
The QL-50D body is zinc-plated tubular steel, which gives you steel strength plus the corrosion resistance of the plating for commercial and industrial installs. For continuously wet or corrosive locations you'd want a fitting specifically listed for that environment.
6) What is the exact part number to order the SEPCO 1/2 inch insulated duplex flex connector?
Order SEPCO model QL-50D. That is the full manufacturer part number and it covers the single configuration this fitting is built in: 1/2 inch, duplex, insulated, Quicklock, zinc-plated steel.
