Appleton 4Q-38T Straight Insulated Liquidtight Connector

Product Description

The APPLETON 4Q-38T is a 3/8-inch straight insulated liquidtight conduit connector designed for securing flexible liquidtight conduit to enclosures, junction boxes, and electrical equipment. The insulated throat protects wire insulation from abrasion at the conduit entry point, a critical detail in installations where conductor integrity matters. This fitting is installed by licensed electricians on commercial, industrial, and residential projects where liquidtight flexible metal or nonmetallic conduit transitions to a threaded knockout. The straight body style provides a direct, in-line connection without angular offset.

This connector is suited for use in wet, damp, or oily environments where standard conduit fittings are not adequate. Typical applications include machine tool wiring, HVAC equipment connections, pump and motor terminations, and outdoor electrical enclosures. The 3/8-inch trade size accommodates the corresponding liquidtight conduit diameter. It is a common fitting in light commercial and industrial control panel builds where flexible conduit runs terminate at enclosure knockouts.

Key Features

• 3/8-inch trade size straight body for direct in-line conduit entry
• Insulated throat reduces abrasion risk to conductor insulation at entry point
• Liquidtight design suited for wet, damp, and oily location installations
• Compact profile at 0.160 inches thickness for tight knockout clearances
• Threaded connection for secure attachment to standard knockout openings

Compatibility

Designed as an OEM-style fitting for 3/8-inch trade size liquidtight flexible conduit systems terminating at standard threaded knockouts on electrical enclosures and junction boxes.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC Article 350 for liquidtight flexible metal conduit or Article 356 for liquidtight flexible nonmetallic conduit. De-energize all circuits and lock out the panel before beginning work at any enclosure knockout. Hand-tighten the connector locknut first, then snug with a strap wrench or locknut tool — do not use standard pliers directly on the fitting body, as this can deform the insulated throat. Verify the conduit and connector trade size match before installation.
