DN125 Pn16 Ss304 EPDM Connector IIR Double Sphere Expansion Joint
Rubber joints, also known as flexible rubber joints, rubber soft joints, or rubber expansion joints, are high-performance pipeline connectors featuring excellent elasticity, airtightness, medium resistance, and weather resistance.
These rubber joints leverage rubber's superior elasticity, gas resistance, medium resistance, and weather/radiation resistance to effectively reduce pipeline vibration and noise while compensating for thermal expansion and contraction.
- Extended sphere design provides superior vibration and noise reduction
- Excellent telescopic displacement performance with longer service life than single ball joints
- Compact, lightweight design with excellent flexibility for easy installation and maintenance
- Absorbs displacement after installation
- Effective noise reduction capabilities

- Install bolts symmetrically and gradually pressurize to prevent local leakage
- For working pressures above 1.6MPa, use elastic pads with installation bolts to prevent loosening
- Provide vertical force support at both ends during vertical installation; consider anti-pull-off devices
- Install away from heat sources, ozone, and avoid strong radiation light exposure
- Handle carefully during transportation - avoid cutting surface or sealing surfaces
