Auto Rieber Ring for Pressure Pipe

Seal Performance

• Design pressure of the sealing ring 2.5 Mpa(code:2776)/1.6Mpa(code:2775)
• Suitable for both cold and hot drinking water applications.
• Ozone resistance and temperature resistance 40 °C~+150 °C (within 4 hours+280C)
• Low insertion force and can bear medium and low pressure.
• Oil and chemical resistance.

Product Function

• Plastic high, medium and low pressure pipe, Automatic ring fit when pipe make belling.
• The sealing ring has been placed in the Rieber ring type socket pipe during the manufacturing and molding process of the plastic pipe, and there is no matching error between the sealing ring and the Rieber ring-type socket pipe.
• The steel wire reinforced structure of the sealing ring makes it have high radial stiffness and realize high stability and reliability.
• lt can effectively eliminate the risk of extrusion of sealing ring.
• The integrated structure of the sealing ring eliminates the possibility of soil or other foreign particles entering between the sealing ring and the inner wall of the pipeline.
• The sealing ring does not have the problem of on-site installation, which avoids the possible mistakes of many on-site manual installations of the sealing ring.
