Single Sphere

expansion joint

Constructed from a single elastomeric sphere reinforced with nylon/steel cord, fitted with flanged or clamped ends. The spherical arch provides high flexibility, minimizes turbulence, and absorbs axial, lateral, and angular deflections. The full-faced flange type improves gasket coverage and sealing reliability in critical installations.

Size Range (DN)

DN25 – DN3000
Materials (Elastomer)

Natural Rubber, EPDM, Nitrile, Neoprene, Hypalon, PTFE-lined on request
Reinforcement

Nylon tire cord with steel wire
Movements

Axial, Lateral, Angular
Pressure Rating

PN10 – PN25 (up to PN40 on request)
Temperature Range

–20°C to +120°C (up to +150°C with special elastomers/PTFE lining)

Typical use case: Installed at pump suction and discharge lines to isolate vibration and protect connected equipment.

Other applications: HVAC and chilled water systems, desalination plants, power plants, oil & gas utilities, and marine piping.

Full-faced flange type: Used where enhanced sealing is required, e.g., chilled water, chemical transfer, or offshore systems.

Compact, easy to install, maintenance-free
Excellent vibration, shock, and noise damping
Absorbs multi-directional movements (axial, lateral, angular)
Reduces water hammer and surge loads
Full-faced flange option enhances sealing and gasket protection
Multiple elastomer grades for varied chemical/temperature service
Long fatigue life and reliable service performance

Flanges
