2-inch (50mm) EPDM threaded connection spherical rubber expansion joint designed for industrial piping systems requiring flexibility, vibration absorption, and thermal compensation.

• High Elasticity & Flexibility: Maintains stable compensation across large expansion ranges to accommodate various pipeline deformation needs
• Corrosion Resistance: EPDM rubber material withstands various media environments for long-term system stability
• Shock Absorption & Noise Reduction: Effectively absorbs vibration and noise to improve system smoothness and reduce equipment wear
• Wide Temperature Range: Operational from -60°C to +110°C with excellent fire resistance properties
• Long Service Life: Superior aging resistance ensures extended performance in demanding applications
• Seismic Performance: Maintains functionality from -40°C to +80°C in low-temperature conditions

• Petrochemical Industry: High-temperature, high-pressure applications with corrosive media to enhance system stability and safety
• Construction & Municipal Engineering: Water supply, drainage, and heating systems to accommodate thermal expansion and reduce vibration
• HVAC Systems: Central air conditioning applications to absorb equipment vibration and maintain operational smoothness

Before installation, ensure both pipe ends are level on a horizontal plane. Screw the threaded rubber joint onto one pipe first, then attach the other end while maintaining level alignment to prevent uneven force distribution. Tighten threaded connections manually or with a wrench, then secure both ends to stable, non-stretching fixtures.
