Appleton 4Q-38 Straight Liquidtight Connector 3/8 Inch

Product Description

The APPLETON 4Q-38 is a straight liquidtight conduit connector designed for 3/8 inch trade size conduit. It provides a secure, watertight termination point where flexible liquidtight conduit meets an enclosure or junction box knockout. This type of connector is a standard component in industrial, commercial, and residential electrical installations where moisture resistance is required at conduit entry points. Licensed electricians install these connectors when running flexible conduit to motors, HVAC equipment, pumps, and other machinery that requires both flexibility and environmental sealing.

The 4Q-38 is suited for use with 3/8 inch flexible metallic liquidtight conduit in straight-run applications where conduit enters a box or enclosure at a direct angle. It is commonly found in mechanical rooms, rooftop HVAC installations, pump stations, and light industrial environments where conduit must transition from rigid wiring to flexible whips. This straight configuration is appropriate where conduit alignment to the knockout does not require an angled fitting.

Key Features

• Straight connector body for direct, in-line conduit entry
• Sized for 3/8 inch trade size liquidtight flexible conduit
• Liquidtight design provides moisture-resistant seal at enclosure knockouts
• Suitable for use on motors, HVAC units, pumps, and similar equipment connections

Compatibility

Designed as an OEM-style replacement or standard-use straight liquidtight connector for 3/8 inch trade size flexible liquidtight metallic conduit terminations at electrical enclosures and junction boxes.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 350 governing liquidtight flexible metal conduit. De-energize the circuit and verify lockout/tagout procedures before making any conduit connections at live enclosures. Thread the connector into the knockout and tighten the locknut securely to maintain the liquidtight seal. Do not over-tighten to the point of deforming the fitting body or gasket.
