Abstract
A tuned convoluted conduit assembly is especially well adapted for use in hostile environments subject to vibrations which bring on fatigue failures. To prevent the conduit from having a uniform resonance throughout its length, the convolutions have a variable wall thickness. One way this variable wall thickness may be achieved is by forming the conduit walls by wrapping tape in successive layers to form a multiple layered wall. The width of the tape may be such that each alternate convolution has more layers than its two adjacent neighboring convolutions. A sleeve or stocking loosely fits over the conduit and is clamped by a band onto the conduit to prevent vibration of the conduit at that clamped location.
