Hubbell Raco 1" Liquid Tight Conduit Fitting

This straight conduit fitting connects 1-inch flexible non-metallic liquid-tight Type B conduit to a 1-inch MNPT box entry. The grey nylon body provides insulation without a separate insulated throat. It is supplied new and carries no hazardous location rating.

Suits installers pulling non-metallic conduit into

Not for metallic conduit systems or applications requiring an external grounding lug. Installers needing strain-relief mesh or hazardous-area certification must select a different fitting.

1-inch MNPT box connection

The fitting threads directly into a 1-inch male NPT opening, determining compatibility with the enclosure. Conduit trade size matches at 1 inch for a secure, liquid-tight seal.

Questions about this item

Will this 1" straight nylon fitting thread onto the 1" MNPT knockout boxes I already have installed?

Yes, the fitting has a 1" MNPT box connection that matches standard 1" knockout hubs, so it threads directly into your existing boxes.

How can I confirm the fitting is properly sealed after I tighten it onto the conduit?

When the compression nut is hand-tight plus one wrench turn, the nylon ferrule compresses evenly around the Type B liquid-tight conduit and the gray body sits flush against the box face, indicating a watertight seal.

Does the package include the locknut and sealing ring, or do I need to buy them separately?

The fitting ships as a single-piece nylon body with integral threads; a 1" steel locknut and a neoprene O-ring must be purchased separately to complete the box connection.
