Product Description


                  high pressure flexible air hose

Stainless Steel Flexible Metal Hose are compensating elements for thermal expansion and relative movement in pumps. They consist of one or more metal bellows and connectors at both ends. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. 

Pump connectors are elastic vessels that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. When the pressure or vacuum is released, the bellows will return to its original shape. 


  • Economical end usage
