Single Sphere Rubber Expansion Joint

Single sphere rubber expansion joints are flexible pipe connectors designed to absorb vibration, reduce noise and compensate for thermal expansion and pipeline movement. They are widely installed near pumps, valves and other equipment in water supply, wastewater, HVAC and industrial piping systems.

XS Pipeline supplies single sphere rubber expansion joints in different sizes, rubber materials, pressure ratings and flange standards to meet different project requirements.

Key Features

Vibration and Noise Reduction
Helps isolate vibration generated by pumps and other pipeline equipment and reduces noise transmission through the piping system.

Movement Compensation
Accommodates axial, lateral and angular movement caused by thermal expansion, contraction and pipeline displacement.

Flexible Rubber Materials
Different rubber compounds can be selected according to the working medium and operating conditions.

Multiple Flange Standards
Flange dimensions can be manufactured according to different international standards and project specifications.

Custom Manufacturing
Size, rubber material, flange material, pressure rating and other specifications can be customized according to project requirements.

Technical Specifications

Rubber Materials

EPDM – Suitable for many water, wastewater and HVAC applications with good resistance to weathering and aging.
