Ipex 300pec Pvc Conduit Expansion Coupling 3 in Sch 40

Product Description

The IPEX 300pec is a 3-inch Schedule 40 PVC conduit expansion coupling designed to absorb thermal expansion and contraction in rigid PVC conduit runs. As PVC conduit heats and cools, it expands and contracts along its length. This fitting allows the conduit system to move without stressing junction points, couplings, or enclosures. It installs in straight conduit runs wherever expansion relief is required, including long runs through unconditioned spaces, exposed outdoor raceways, and large commercial or industrial installations. Licensed electricians and electrical contractors are the primary installers of this fitting.

This expansion coupling is suited for use in 3-inch Schedule 40 PVC conduit systems in both residential and commercial electrical applications. It is commonly installed in long straight conduit runs on exterior walls, rooftops, parking structures, and similar environments where temperature swings are significant. The fitting is especially important in runs exceeding 100 linear feet where thermal movement would otherwise build up stress at fixed coupling points.

Key Features

• Accommodates thermal expansion and contraction in rigid PVC conduit runs
• 3-inch trade size fits Schedule 40 PVC conduit
• PVC construction resists moisture, corrosion, and most chemicals
• Designed for long conduit runs in temperature-variable environments
• Suitable for exposed outdoor and unconditioned-space installations

Compatibility

Designed as an OEM-style replacement and standard fitment for 3-inch Schedule 40 PVC rigid conduit systems.

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 and lock out power before working on any conduit system. Use appropriate PVC conduit cement and primer on solvent-weld joints per manufacturer instructions. Consult NEC expansion joint placement guidelines for proper spacing on long conduit runs.
