Abb E945E-CAR Pvc Expansion Coupling 3/4 Inch Conduit

Product Description

The ABB INSTALLATION PRODUCTS E945E-CAR is a two-piece PVC electrical conduit expansion coupling designed to compensate for length changes caused by temperature variations in exposed conduit runs. The fitting features a 4-inch travel distance, allowing the piston to move freely as the conduit expands and contracts. A molded-in midpoint indicator on the piston gives installers a clear reference for centered positioning during installation. Lubricated seals and two O-rings are built into the assembly to prevent leakage and maintain smooth movement over the life of the fitting. Licensed electricians and conduit installers use this coupling in exposed above-ground conduit systems where thermal cycling is a concern.

This expansion coupling is intended for use with Schedule 40 and Schedule 80 PVC conduit in 3/4 inch trade size. It is suited for exposed outdoor and indoor conduit runs that span long distances or cross building expansion joints, where thermal movement must be absorbed without stressing the conduit system. The two-piece molded design supports both vertical and horizontal installation orientations, making it adaptable to a wide range of routing configurations in commercial, industrial, and utility electrical work.

Key Features

• 4-inch travel distance accommodates significant thermal expansion and contraction
• Molded-in midpoint indicator on the piston for accurate centered installation
• Two O-rings provide a sealed, leak-resistant connection
• Lubricated seals enable smooth piston movement throughout the product life
• Two-piece molded construction for straightforward field assembly
• Installs vertically or horizontally to suit varied conduit routing

Compatibility

Designed for use with 3/4 inch Schedule 40 and Schedule 80 PVC electrical conduit.

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 confirm the conduit run is not under tension before installing the coupling. Ensure the piston midpoint indicator is centered at time of installation so the fitting has equal travel capacity in both directions. Do not use solvent cement on the expansion coupling joints, as the sliding fit must remain free to move.
