Liquid-tight cord connector

The Hubbell Raco 4704-3 provides a liquid-tight seal for a single cord measuring .63 to .75 inches in diameter. Its straight nylon body threads into a 1-inch MNPT opening and extends 1.75 inches from the box face. The gland is colour-coded purple while the connector body is black, and the assembly is insulated. It carries no hazardous-location rating.

Replaces open knockouts or non-sealed fittings

Use this connector when an enclosure must stay dry and the existing opening is a 1-inch MNPT threaded hub. The jump is worth it where moisture, oil or dust would otherwise enter around an unsealed cable entry. Installers who do not need an external strain-relief device will find the low-profile design simpler to fit.

Handles one cord in the .63 to .75 inch range

The connector accommodates a single conductor within that diameter window and seals against liquids at the gland. It runs out of headroom when the cord exceeds .75 inches or when a second cable must pass through the same fitting. Applications requiring hazardous-location approval or an integrated strain-relief component are not served by this model.

Questions about this item

What size knockout does the 1 in MNPT thread require?

The connector uses a 1 in MNPT thread, which fits a standard 1 inch trade-size knockout in the enclosure.

How do you tighten the gland nut without damaging the .63 to .75 in cord range?

Insert the cord through the body, then hand-tighten the gland nut until the purple gland compresses evenly around the jacket; overtightening can crush the insulation.

When should the nylon body or purple gland be replaced?

Replace the connector if the nylon body shows cracks, the purple gland stays deformed after cord removal, or the threads no longer seal at the 1.75 in installed length.
