Chicago Plenum Flexible Metal Tubing & Fitting

Our Chicago plenum flexible metal tubing (PFMT Series) is manufactured to meet the City of Chicago's local electrical code, which requires flexible metal tubing rather than standard flexible metal conduit for concealed wiring runs in plenum spaces and other applications specific to the Chicago market. The tubing's continuous, close-wound steel construction provides mechanical protection for conductors while remaining flexible enough for tight routing around structural obstructions.

It is paired with the S27 Series straight, male-threaded fitting, engineered for a secure mechanical connection between the tubing and junction boxes, panels, or equipment housings without the need for additional sealant.

As the manufacturer, we produce both the tubing and fitting in-house, allowing us to offer custom coil lengths, thread sizes, and finishes for contractors and distributors supplying the Chicago metro market.
