There are two type of vacuum bellows of Htc's products. "Flexible Hoses" have concertina walls made by pressurizing a thin-wall tube. They can be bent, but not be compressed. The other type is "Flexible Bellows Connections." This type can be bent and compressed.
When possible, design the system so that the bellows make only a single bend or curve. Multiple bends concentrate stress at minimum radius points, reducing life expectancy during flexing or vibration. An elbow on one or both ends will usually eliminate multiple bends. It is difficult to make a short bellows fit between parallel flange faces that are not coaxial.
