FAQ — tubing and connections for compressed air and vacuum
It depends on the material and construction. Some tubes are designed specifically for vacuum applications and must be selected according to the required negative pressure.
No. Fittings, flow regulators and in-line valves do not perform logical control functions, but handle circuit connection, regulation and safety.
Yes. The components are compatible with most industrial pneumatic systems and enable retrofits and modifications without structural work.
Yes. Fluid System specialists support the selection of the most suitable components for performance, safety and long-term service life.
