Product Overview

This flanged EPDM flexible rubber expansion joint serves as a critical pipeline compensator for industrial fluid piping systems. Constructed with multi‑ply fabric reinforcement inside, it absorbs multi‑directional pipeline displacement, isolates vibration and cuts operating noise. It protects pipelines and connected equipment effectively from thermal stress and installation misalignment. Made of EPDM rubber, it features outstanding weather‑resistance, ozone‑resistance and anti‑aging performance, suitable for long‑term service under outdoor and harsh‑medium working conditions.

Core Features

✅ Multi‑direction compensation: absorbs axial, lateral and angular displacement ✅ Vibration damping & noise reduction for pump and fan connected pipelines ✅ EPDM rubber body: anti‑aging, ozone‑proof, weak acid‑alkali corrosion resistance ✅ Flange connection for easy installation and maintenance ✅ Customizable size, pressure grade and flange material ✅ Widely applied in water treatment, HVAC, sewage and general industrial piping
