Publication number: 20240125414Abstract: A bellows member (10) for use in connecting two plumbing interfaces to one another. The bellows member is a generally hollow design with cuff ends (12, 14), each of which connects to an ends of another interface. The bellows member has a flexible bellows body center section that moves to accommodate operational off-axis misalignment, while being able to absorb vacuum and pressure differentials. The disclosed bellows resists vacuum implosion and internal pressurization. The flexible center section is provided with a plurality of convolutes (34, 36, 38) oriented radially outwardly on a horizontal axis. The bellows functions to accommodate misalignment between the two plumbing interfaces.Type: ApplicationFiled: May 4, 2021Publication date: April 18, 2024Inventors: James W.
