Thomas Betts t28-4x-g Type T Conduit Body 3/4 in Nema 4X

Product Description

The THOMAS BETTS t28-4x-g is a Type T PVC-coated iron conduit body from the Ocal-Blue series, rated for NEMA 4X enclosure environments. It provides a pull point, splice point, or direction change in a conduit run while delivering corrosion-resistant protection suited to wet, corrosive, or washdown-rated installations. The body features three 3/4-inch NPT hubs and an internal capacity of 9 cubic inches, meeting Form 8 requirements for conductor fill. Dark gray in color, it is sized at 6.28 inches long by 2 inches wide by 2.31 inches tall. Licensed electricians and conduit installers working in industrial, marine, or chemical environments are the primary installers.

This conduit body is designed for use in raceway systems requiring NEMA 4X-rated components, such as food processing facilities, wastewater treatment plants, marine installations, and other corrosive or high-moisture environments. The PVC coating over the iron base provides an added barrier against chemical attack, salt spray, and prolonged moisture exposure. It is suitable for use with 3/4-inch trade-size rigid or IMC conduit runs where a T-configuration pull or junction point is needed.

Key Features

• NEMA 4X rating provides protection against corrosion, windblown dust, and water ingress
• PVC coating over iron body for enhanced chemical and moisture resistance
• Three 3/4-inch NPT hubs in Type T configuration for inline pull or branch routing
• 9 cubic inch internal capacity meets Form 8 conductor fill requirements
• NPT threaded connection for use with rigid or IMC conduit systems
• Dark gray finish consistent with Ocal-Blue series corrosion-resistant conduit fittings

Compatibility

Designed as an OEM-style fitting for 3/4-inch trade-size rigid metal or IMC conduit systems requiring NEMA 4X-rated conduit bodies in corrosive or wet location installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the raceway before opening or installing conduit bodies. Avoid using pipe wrenches or overtightening on the PVC-coated surfaces, as this can damage the protective coating and compromise the corrosion rating. Ensure the cover gasket and cover screws are properly seated and torqued per the cover hardware requirements to maintain the NEMA 4X enclosure rating.
