Threaded Rubber Expansion Joint OG111 – Vibration Damping and Movement Compensation
The threaded rubber expansion joint type OG111 is a twin-sphere compensator for absorbing axial, lateral and angular movements in piping systems. The EPDM bellows with nylon reinforcement dampens vibrations, pressure surges and thermal expansion – protecting connected pumps, valves and pipelines from mechanical overload.

- Connection: female thread per BSPP (F-F)
- Bellows: EPDM, nylon-reinforced, twin-sphere
- End fittings: ductile iron, galvanised
- Face-to-face length: 203 mm
- Max. operating pressure: 16 bar (PN10/PN16)
- Operating temperature: −10 °C to +110 °C
Applications
The rubber expansion joint OG111 is used wherever pipelines need protection against vibrations and thermal stress:
- Process lines and pump stations
- Heating, cooling and HVAC systems
- Wastewater and water treatment
- Shipbuilding and offshore installations
- Industrial piping networks with frequent temperature changes
For aggressive media, optional PTFE or Hypalon linings are available on request.
