These braided bellows hose are often used as flexible couplings and have 2.75 inch Conflat flanges (2-3/4 CF vacuum connections). These flexible couplings have a protective stainless steel braided covering which helps protect the delicate bellows hose from puncture or mechanical wear when used in applications with constant vibrations, such as roughing lines on mechanical pumps. This braided covering is not designed for over pressure protection. These conflat flange (CF) flexible couplings have CF 2-3/4 inches vacuum flanges, are 18.75 inches long, and have an external braid for protection, are made of stainless steel, and have Agilent Varian part number FLB01501875.
