suction hose /dredging hose

Decription:

 

Suction Hose mostly used with thesehoses are the rubber flange/steel backing

 

flange and theDouble Action flange. They can be supplied in any size,and

 

depending on application, with 100% vacuum capability and high implosion

 

pressures. In some applications heavy spring steel spirals are used to prevent

 

the hose from kinking. Spring steel spirals absorb these peak loads without the

 

risk of collapsing.
