Thomas & Betts 5330 Insulated Liquidtight Connector

Description:

The Thomas & Betts 5330 One-Piece Straight Insulated Liquidtight Connector is used to securely terminate 5/16 inch liquidtight flexible metal conduit (LFMC) to electrical enclosures while providing a watertight, oil-tight, and dust-tight seal. Commonly installed in industrial machinery, control panels, HVAC equipment, manufacturing facilities, and commercial electrical systems, this one-piece steel connector protects conductors and maintains enclosure integrity. Maintenance teams and electrical contractors use this fitting for repair, retrofit, expansion, and replacement of liquidtight conduit installations.

Applications:

The Thomas & Betts 5330 is designed to connect 5/16 inch liquidtight flexible metal conduit to threaded electrical enclosures, junction boxes, and equipment housings. Its one-piece construction simplifies installation while the thermoplastic insulated throat protects conductor insulation from abrasion. The electro-zinc plated steel body provides corrosion resistance and creates a positive seal against moisture, oil, liquids, and dust, making it suitable for indoor and outdoor industrial and commercial applications.
