Exhaust Connectors

Senior Flexonics is regarded as a world leader in the manufacture and supply of automotive exhaust connectors (flexible decouplers). The exhaust connectors enable customers to meet stringent environmental emission standards and are also used for motion compensation, noise isolation, minimizing vibration and to mitigate harshness in exhaust systems.


Interlock Hoses

Senior Flexonics interlock hoses are used in a variety of applications and available in a range of sizes. Pre-formed stainless steel strip is wound around a mandrel to form interlocking convolutions with excellent flexing capabilities.


Co-axial Heat Exchangers

We manufacture co-axial heat exchangers developed by our sister company. The co-axial heat exchangers are highly thermal compliant and ideal for intermediate/additional cooling.


Concentrated Solar Bellows

Our Concentrated Solar Power (CSP) bellows prevents the heat transfer medium from escaping at high temperatures and pressures to generate sustainable and environmentally friendly power. The bellows compensates for thermal expansion, vibration and assembly misalignment.

Exhaust Gas Recirculation (EGR) Tubes and Bellows

Our corrugated thin-wall, flexible EGR tube provides high-temperature durability and minimizes installation problems.

Our purpose-designed EGR bellows reduce vibration between the EGR cooler and the engine. These EGR solutions are available to both the passenger vehicle and heavy-duty diesel engine markets.

Load-Bearing Connectors

Our sturdy, load-bearing connectors decouple engine movements and vibrations. An internal sub-assembly with interlocking wire mesh ring restricts axial movement, giving it load-bearing capabilities.

Industrial Products

Senior Flexonics has 13 world-class manufacturing plants in 11 countries. Senior Flexonics Cape Town is therefore able to source products for industrial process control applications from these sites and supply them to energy, petrochemical, steel, vacuum, HVAC, wood and paper manufacturing operations in Southern Africa.
