Expansion Joints made of rubber (EPDM) or PTFE

Rubber and PTFE expansion joints are commonly used in industrial, OEM and HVAC applications.
Typical examples are:
- Chemical and petrochemical industry
- HVAC installations
- Shipbuilding
- Piping

The main difference between rubber and PTFE expansion joints is the corrosion resistance and temperature range, in which they are operating:
EPDM: -20°C up to +100°C
PTFE: -70°C up to +260°C
Rubber expansion joints cost less than PTFE products.

Due to their extensive chemical resistance, they can be used in pipeline systems carrying various media such as:
- hot water
- cool water
- warm water
- compressed air
- cooling water
- sea water
- acid solutions
- alkaline solutions
- oil
- oil-containing media
etc. depending on the rubber quality (see tables, downloads)

Rubber expansion joints are particularly suited to:
- compensate mechanical vibrations
- compensate axial and lateral movements
- compensate installation misalignments
- noise reduction
