Product Description

The DN65 Screw Threaded Rubber Flexible Joint Pipe Connector is expertly crafted to provide effective noise reduction, vibration isolation, and the flexibility needed to handle thermal expansion in piping systems. Its rubber body, combined with reinforced fabric and a metal threaded connection, gives it the ideal balance of strength and flexibility.

When installed, the connector offers excellent elasticity, absorbing vibrations that would otherwise be transmitted through the pipe system, thereby reducing the noise levels significantly. The rubber compound used in the connector ensures superior corrosion resistance, even in harsh environments, making it the perfect choice for pipelines carrying sea water, oils, gases, and other media prone to chemical exposure.

Experience the benefits of a quieter and more stable system, where vibrations and shocks are absorbed efficiently, extending the lifespan of your piping system and reducing the need for frequent maintenance.

With its high-quality materials, flexibility, and ease of installation, it is the ideal choice for industries requiring long-lasting, reliable, and efficient pipeline solutions.

Whether you're working with HVAC systems, water treatment facilities, or any industrial application that requires flexible pipe connections, this product provides the stability and performance you need for seamless operations.


Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage.


Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage.

Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system.

Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
