Single Sphere

SINGLE SPHERE RUBBER EXPANSION JOINTS

Product Overview

TOTFLEX T270 Single Sphere Rubber Expansion Joints are engineered flexible connectors designed to reduce vibration and noise, compensate thermal expansion, and accommodate minor pipeline misalignment in HVAC, water, and industrial piping systems. Available in multiple rubber compounds and flange drilling options for common piping standards.

Advantages

- Vibration & noise isolation to protect connected equipment
- Thermal movement compensation (expansion/contraction in pipe runs)
- Misalignment tolerance for easier installation and reduced strain
- Lower stress at pumps/valves to support longer service life of components
- Selectable rubber compounds to match media and temperature needs
- Multiple flange drilling options (EN / ANSI) for broad compatibility

Application Areas

- HVAC: chilled water, hot water, condenser lines
- Pump rooms: suction/discharge lines (stress reduction at equipment nozzles)
- Water & wastewater: treatment plants, distribution, utility rooms
- Industrial process lines: general service fluids (compound selection dependent)
- Compressed air lines (compound selection dependent)
