RACO 4728 Liquid-Tight Conduit Connector

The RACO 4728 is a straight, two-inch liquid-tight conduit fitting made from grey nylon. It connects flexible non-metallic Type B conduit to a matching knockout or threaded box entry. The connector suits electricians and maintenance crews who need a corrosion-resistant, non-metallic termination for wet or outdoor locations.

Replacing metallic or non-insulated fittings

This nylon fitting replaces metal connectors when weight, chemical resistance or non-conductivity are priorities. The jump is worth it when the installation demands a lightweight, grey-coloured termination that will not corrode and does not require an insulated throat or external grounding lug.

Simple straight-thread installation

The connector threads straight onto a two-inch MNPT box connection or knockout; no strain-relief mesh or special tools are required. Common issues arise if the conduit is not fully seated before tightening or if the threads cross on the non-metallic conduit, so verify alignment before final torque.

Questions about this item

What size knockout does the RACO 4728 connector fit?

It fits a 2 in trade-size knockout for straight-through entry into a box or enclosure.

How do you secure the conduit to the nylon body without damaging the threads?

Hand-tighten the compression nut until the ferrule grips the flexible Type B conduit, then add one-quarter turn with a wrench; over-torquing strips the nylon threads.

When should the gray nylon fitting be replaced after exposure to sunlight?

Replace it if the gray body shows chalking, cracking or loss of flexibility, which indicates UV degradation of the nylon material.
