American Fittings FLX Steel Flexible Connector with Insulated Throat

The American Fittings FLX Series is a line of steel flexible conduit connectors engineered to join flexible metal conduit (FMC) to boxes, panels, and equipment enclosures. The series is available in trade sizes from 1/2" through 1" (1/2", 3/4", and 1"), so installers can standardize on a single connector line across a range of FMC terminations.

The FLX Series is UL Listed to UL 514B and UL 467 and meets NEMA FB 1 standards for fittings and conduit bodies, making it well suited for commercial and industrial electrical systems where domestic sourcing and strict code compliance are required.

American Fittings FLX100B – Frequently Asked Questions

1) What trade sizes do American Fittings FLX flexible conduit connectors come in?
The FLX steel flexible connectors are ordered by trade size, and the line runs 1/2 inch (FLX50B), 3/4 inch (FLX75B), 1 inch (FLX100B), 1-1/4 inch (FLX125B), 1-1/2 inch (FLX150B), 2 inch (FLX200B), 2-1/2 inch (FLX250B) and 3 inch (FLX300B). Match the connector trade size to the flexible metal conduit trade size, not to the knockout.
2) Are these FLX connectors for flexible metal conduit or for EMT?
They terminate flexible metal conduit (FMC) into boxes, panels and equipment enclosures. EMT is rigid thinwall tubing and takes a set screw or compression EMT connector instead, so don't substitute an FLX here. Typical FLX uses are motor and equipment hookups, panelboard and junction box terminations, and renovation work where flex is run to a device.
3) Will American Fittings FLX connectors pass a Buy American Act spec on a federally funded job?
Yes. The FLX connectors are made in the USA with United States country of origin, and are flagged Buy American Act compliant and ARRA compliant. They are also built to Federal Spec No. A-A-50553, which is the line most government and institutional specs reference for this fitting type.
4) Do I still need a plastic bushing when I use one of these connectors?
No. Every FLX connector has an insulated throat molded in, so the conductor insulation is protected from abrasion as wires are pulled through. That is the point of the insulated throat version, and it saves adding a separate bushing at the box.
5) Are the FLX connectors steel or die cast zinc?
Steel. The FLX body is steel, which gives it mechanical strength and reliable grounding continuity through the fitting. If your spec calls out die cast or malleable iron specifically, this is not that fitting.
6) Can I standardize my whole building on one connector line for flex terminations?
Yes, that is how the FLX series is set up. One steel connector line with an insulated throat covers trade sizes from 1/2 inch through 3 inch, so small device drops and larger motor feeders both terminate with the same fitting family, the same UL 514B and UL 467 listing, and the same domestic sourcing paperwork.
7) Do these connectors meet RoHS and Prop 65 requirements for our institutional purchasing policy?
They do. The FLX line is RoHS compliant, REACH compliant, CA Prop 65 compliant, and certified conflict-minerals free. Paired with the US country of origin, that covers most institutional and government procurement screens in one part number.
