Product Details

A ‌rubber joint‌ (commonly called a ‌rubber expansion joint‌, ‌flexible rubber connector‌, or ‌compensator‌) is a flexible connector used in piping systems to absorb movement, reduce noise/vibration, and compensate for misalignment.
 
‌Core Functions
1.‌Thermal Expansion‌: Compensates for pipe elongation/shrinkage due to temperature changes.
2.‌Vibration Damping‌: Isolates vibrations from pumps, compressors, or machinery.
3.‌Misalignment Tolerance‌: Accommodates minor pipe offsets (angular, lateral, or axial).
4.Prevents transfer of forces to valves, flanges, or equipment, extending system life.
 
Key Applications
1.‌HVAC Systems‌: Chiller/pump connections, ductwork.
2.‌Water/Wastewater‌: Treatment plants, pipelines (absorbs water hammer).
3.‌Industrial Piping‌: Chemical plants, power generation, marine/shipbuilding.
4.‌Hydraulics & Pneumatics‌: Dampens pulsations in high-pressure lines.
