Appleton 4Q-50 Straight Liquidtight Connector 1/2 Inch

Product Description

The APPLETON 4Q-50 is a straight liquidtight conduit connector designed for use with liquidtight flexible metal or nonmetallic conduit systems. This fitting provides a secure, watertight termination point where flexible conduit meets an enclosure or junction box knockout. At 1/2 inch trade size, it is one of the most common connector sizes used in commercial and industrial electrical installations. Licensed electricians rely on this type of fitting to maintain conduit integrity in wet, damp, or oil-exposed environments where standard fittings would not meet code requirements.

This connector is suited for use in residential, commercial, and light industrial applications where liquidtight flexible conduit must terminate at a panel, enclosure, motor, or electrical box. Straight-body connectors like the 4Q-50 are typically used when the conduit run approaches the knockout from a direct angle without requiring a bend at the fitting. Common applications include HVAC equipment connections, pump motor wiring, and outdoor electrical enclosures subject to moisture exposure.

Key Features

• Straight-body configuration for direct-angle conduit terminations
• 1/2 inch trade size fits the most common liquidtight flexible conduit diameter
• Liquidtight design provides a watertight seal at the enclosure entry point
• Suitable for wet, damp, and oil-resistant installation environments
• Compatible with standard knockout openings on electrical enclosures and panels

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch liquidtight flexible conduit systems in commercial and industrial electrical applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) requirements for liquidtight fittings. De-energize all circuits before working on any enclosure or panel where this connector will be installed. Hand-tighten the locknut first, then use an appropriate wrench to secure the fitting without overtightening the conduit or deforming the knockout. Verify the conduit sealing ring is properly seated to maintain the liquidtight rating after installation.
