The EJ35 2" PVC O-Ring Expansion Joint is an essential fitting designed to protect rigid PVC conduit systems from the damaging effects of thermal expansion and contraction. When PVC conduit is exposed to temperature fluctuations—such as on rooftops, exterior walls, or outdoor installations—the conduit can shift several inches, leading to bending, cracking, or separation. This expansion joint installs inline with 2-inch rigid PVC conduit and features a sliding piston with an internal O-ring seal, allowing up to 4 inches of controlled movement while maintaining a secure, weather-resistant connection. It is ideal for long outdoor conduit runs, rooftop solar installations, parking structures, bridges between buildings, and industrial facilities with exposed conduit. The gray PVC construction is compatible with Schedule 40 and Schedule 80 rigid PVC conduit systems. Designed for electricians and contractors, this fitting helps ensure compliance with NEC requirements for PVC conduit expansion, extending the life of your electrical raceway system and reducing the risk of costly repairs.
