Kraloy 078334 EJ25 PVC Expansion Joint

Kraloy 078334 EJ25 2-1/2" PVC Expansion Joint

The Kraloy 078334 EJ25 2-1/2" PVC Expansion Joint is a purpose-built expansion fitting designed for rigid PVC conduit systems where conduit runs are exposed to temperature fluctuations that cause the pipe to expand and contract. Sized for 2-1/2" trade size PVC conduit, this expansion joint is manufactured from PVC to match the material composition of standard PVC conduit, helping maintain consistent chemical resistance, weather resistance, and electrical continuity throughout the raceway system. As part of Kraloy's EJ25 series of PVC expansion joints, this fitting is engineered to be installed inline with 2-1/2" PVC conduit runs to help relieve stress on the conduit system caused by thermal movement, reducing the risk of cracked or damaged conduit over time. Electrical contractors specifying PVC conduit for commercial, industrial, or outdoor installations can rely on the Kraloy 078334 EJ25 expansion joint to complement their existing PVC conduit and fitting selections.

Key Features

• Trade Size: Sized for 2-1/2" PVC conduit, allowing this expansion joint to be installed directly into 2-1/2" trade size PVC conduit runs without the need for additional reducers or adapters.
• PVC Construction: Molded from PVC material to match the composition of standard PVC conduit and fittings, supporting consistent corrosion resistance and compatibility across the conduit system.
• Expansion Joint Design: Engineered as an expansion joint to help accommodate conduit movement caused by thermal expansion and contraction, which is especially important on long, exposed PVC conduit runs.
• EJ25 Series: Identified as part of the Kraloy EJ25 series of PVC expansion joints, a dedicated product line for PVC conduit expansion applications.
• Model Number 078334: Factory-identified by Kraloy under item number 078334 for accurate specification and ordering.
