Atkore 5144038 Epvc Expansion Joint 3 Inches

Product Description

The ATKORE 5144038 is a 3-inch EPVC expansion joint designed to accommodate thermal expansion and contraction in electrical conduit systems. EPVC, or encapsulated PVC, combines the corrosion resistance of PVC with added structural integrity, making this joint well suited for conduit runs exposed to temperature cycling. Licensed electricians and electrical contractors install this type of fitting where long conduit runs require a controlled flex point to prevent stress cracking, coupling failure, or conduit misalignment over time.

This expansion joint is sized for 3-inch conduit systems and is commonly used in commercial and industrial electrical installations where extended straight runs of PVC conduit pass through areas subject to significant ambient temperature swings. Typical applications include exposed exterior conduit runs, rooftop installations, large commercial building electrical raceways, and conduit systems transitioning between indoor and outdoor environments.

Key Features

• 3-inch trade size fits standard 3-inch EPVC conduit systems
• EPVC construction provides corrosion resistance suitable for outdoor and industrial environments
• Accommodates thermal expansion and contraction to protect conduit integrity over long runs
• Catalog number 5144038 for straightforward procurement and replacement ordering

Compatibility

Designed as an OEM-style replacement and standard fitting for 3-inch EPVC conduit systems in commercial and industrial electrical 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 the circuit and lock out the system before working on any conduit assembly. Follow manufacturer spacing recommendations for expansion joint placement based on expected temperature differential across the conduit run. Do not over-cement the joint slip section, as this can restrict the designed range of movement.
