Under the ‘Hydroflex ™ brand, Maineport is a leading global supplier of precision bellows and assemblies for diverse applications and market sectors.

The versatility of metallic bellows as an engineering device means that they are found not only in every-day products such as thermostatic valves, but also in high technology equipment found in aerospace and medical applications.

Bellows can be produced using various technologies, depending on the application, to produce single or multi-ply units with a number of convolutions – the term used for the shape of the bellows form.

Most precision bellows are manufactured by the hydroforming process, where a thin-walled plain tube is internally pressurised and simultaneously collapsed along its axis to form convolutions in the tube wall.

The tube may be only a few microns thick, and therefore the selection and manufacture of appropriate materials is critical to bellows performance and integrity.
