Transporting Fluids
In internal combustion engines, rubber air fittings, or air ducts, are the components that enable air to be transported through the air intake system.
Depending on their location within the air intake system, they enable air to be directed:
- Between the air intake and the air filter
- Between the air filter and the intake manifold
- In the turbocharger or supercharger
SACRED EXPERTISE
Very often, the material is a critical aspect of the specification. Our laboratory can develop customised compounds to meet your specific needs in terms of resistance to temperature, oil and ozone. A non-exhaustive list of our materials validated with OEMs includes EPDM, NBR/PVC and AEM, covering a wide range of operating temperatures.
SACRED has expertise in the injection moulding of air fittings, with low-, medium- and high-speed production volumes for ducts carrying a wide variety of weights. We use aluminium or steel injection moulds with optional cold-runner systems, automated-piston or manual-insert systems and fixed or mobile core clamps.
DISTINCTIVE DESIGN
Windings, ribbing and thicknesses are used to adjust the flexibility/rigidity to comply with the requirements of the tests for collapse and engine roll, while ensuring that the air fitting is compatible with the available space. Our design team is able to guide you as you develop the geometry of the component, taking into consideration its functional aspect and manufacturing feasibility.
