Hubbell RACO 3428 Conduit Fitting

The Hubbell RACO 3428 is a non-insulated liquid-tight conduit fitting designed for electrical installations requiring a 90-degree directional change. It suits contractors and maintenance teams joining flexible metallic or non-metallic Type B conduit to a 2-inch MNPT box connection. The gray malleable iron and steel construction provides mechanical protection for wiring in commercial and industrial environments.

Thermal and Power Characteristics

As a passive conduit fitting, the RACO 3428 generates no heat, produces no noise and draws no electrical power during operation. Its malleable iron and steel body simply channels and protects conductors without introducing thermal load or acoustic signature to the installation. The component remains electrically neutral and thermally inert throughout its service life.

Build Integration and Clearance

The 90-degree elbow orientation routes conduit perpendicular to the enclosure, saving space in tight panel layouts where a straight connector would protrude. It accepts flexible liquid-tight metallic conduit and flexible liquid-tight non-metallic Type B conduit without requiring strain-relief mesh. The fitting threads directly into a 2-inch MNPT hub, leaving the installer to supply compatible conduit, locknuts and sealing materials for a complete liquid-tight assembly.

Questions about this item

How is the 90-degree conduit fitting installed and which step is often missed?

Thread the 2-inch MNPT end into the box, insert the flexible liquid-tight conduit into the body, then tighten the compression nut until the ferrule grips the conduit jacket; the step often missed is fully seating the conduit before final tightening.

What maintenance or replacement will the RACO 3428 need over time?

Inspect the gray malleable iron body and steel compression nut for corrosion or cracked threads; replace the fitting if the ferrule no longer seals the conduit jacket or if the 90-degree bend shows metal fatigue.

What limit appears first when the 3428 fitting runs under continuous vibration or thermal cycling?

The compression seal on the flexible liquid-tight metallic or non-metallic Type B conduit typically loosens before the iron body or steel nut fails, requiring re-torquing to maintain liquid-tight integrity.
