Rubber Expansion Joint OG150 – Flanged Compensator with Steel or Stainless Steel Flanges
The rubber expansion joint type OG150 is a flanged pipeline compensator for absorbing axial,
lateral and angular movements. The rubber bellows dampens pump and compressor vibrations,
compensates thermal expansion and absorbs pressure surges – protecting connected pipelines,
valves and equipment from mechanical overload.
- Nominal sizes: DN25 to DN600 (standard variants: DN32–DN300)
- Flange connection: PN10, PN16 per
DIN EN 1092-1 - Face-to-face lengths: 130 mm, 152 mm, 203 mm
- Bellows materials: EPDM or Nitrile/CR (nylon-reinforced)
- Flange materials: galvanised steel or stainless steel
Three Variants – Choose Bellows and Flange Material
- OG150-LEF – EPDM rubber expansion joint with steel flanges: standard
solution for water, hot water, wastewater, air and aqueous media. −30 °C to +110 °C.
Most cost-effective option for general piping applications. - OG150-LNF – Nitrile/CR rubber expansion joint with steel flanges:
nylon-reinforced bellows (yellow colour code) for oil-bearing media, hydrocarbons,
hydraulic fluids and fuels. Max. +90 °C (pressure-dependent). - OG150-SEF – Stainless steel flanged rubber expansion joint: EPDM bellows
with stainless steel flanges for corrosive environments, chemical and food installations,
and ultrapure water systems. −30 °C to +110 °C.
Applications for the Flanged Rubber Compensator
- Pump stations and pressure boosting – vibration isolation
- Heating, cooling and HVAC systems – thermal expansion
- Water and wastewater treatment
- Chemical process plants and food industry (stainless steel)
- Shipbuilding and offshore – sea and vessel movements
- Power plants and energy technology
- Oil-bearing systems and hydraulic installations (Nitrile/CR)
Special Designs and Linings
For aggressive media or elevated temperatures, Fergo supplies the OG150 with PTFE or Hypalon
linings. Tie rods for axial movement limitation and custom face-to-face lengths up to 1500 mm
are also available on request.
