flexible pipe connection
1. A nonmetallic airtight connection in ductwork, between a fan and a duct or between ducts, to prevent the transmission of vibration along the duct.
2. In a piping system, a connector, usually fabricated of a combination of metallic mesh and a nonmetallic material; used to minimize the transmission of vibration along the piping system (as between pipes or between a pipe and a pump, etc.) or to reduce pipe misalignment.
3. An electric connection that permits the contraction, expansion, or relative motion between connected parts of rotating machinery.
