UL 1653 Listed ENT Electrical Non-Metallic Tubing (Smurf Tube)

Our UL 1653 listed Electrical Non-Metallic Tubing (ENT), commonly known as "Smurf Tube," is a lightweight, corrugated, hand-bendable conduit designed for fast rough-in wiring in residential and commercial construction. The pliable PVC wall lets electricians shape bends by hand without a bending tool, speeding up installation inside walls, ceilings, and slab floors.

The PENT Series is rated for use within walls, floors, and concrete encasement per UL 1653 requirements, and it carries a flame-retardant rating suited to standard building electrical codes. Its smooth interior bore makes cable pulling easier compared to rigid conduit, while the corrugated exterior keeps the tubing flexible around framing and obstructions.

As the manufacturer, we supply PENT Series ENT tubing in standard coil lengths and custom diameters for large-volume construction and distribution orders, with private labeling available on request.
