Hubbell H0381 3/8 in Liquid-tight Conduit Connector

Product Description

The HUBBELL WIRING DEVICE-KELLEMS H0381 is a straight, compression-style conduit connector designed for use with liquid-tight flexible conduit. Constructed from malleable iron and steel, it provides a durable, insulated termination point where liquid-tight conduit meets an enclosure or junction box. The H0381 carries a 3/8 inch trade size and delivers a watertight, dust-resistant seal when properly installed. Its compression connection method ensures a secure mechanical grip on the conduit without requiring additional fittings or adhesives. Licensed electricians and electrical contractors install this type of fitting during conduit runs in industrial, commercial, and residential applications where moisture or particulate exposure is a concern.

This connector is suited for environments requiring dust-resistant and watertight conduit terminations. Typical installations include machinery wiring, HVAC equipment connections, control panel wiring, and any application where liquid-tight flexible metal or non-metallic conduit must be terminated at a 3/8 inch knockout. The straight profile makes it appropriate for direct, in-line conduit entries into enclosures where angled clearance is not a limiting factor.

Key Features

• 3/8 inch trade size fits standard 3/8 inch liquid-tight flexible conduit
• Compression connection type provides a secure, tool-assisted mechanical grip
• Malleable iron and steel construction for durability in demanding environments
• Insulated fitting reduces risk of ground fault at the conduit termination point
• Straight connector shape allows direct, in-line conduit entry
• Rated for dust-resistant and watertight applications

Compatibility

Designed as an OEM-style replacement connector for 3/8 inch trade size liquid-tight flexible conduit systems in residential, commercial, and industrial electrical installations.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit and verify absence of voltage before making any conduit connections at an enclosure. Ensure the knockout diameter matches the 3/8 inch trade size before installation, and use appropriate hand tools to tighten the compression nut to a secure, watertight fit without overtightening malleable iron threads.
