A complete coupling assembly consists of coupling housing pair, nuts, bolts, and gasket. The coupling housing contains and compresses the gasket, which effects proper sealing of the joint. Piedmont gaskets are designed for a tight seal in high pressure industrial applications.
Piedmont offers two different shapes of gaskets: C-Shaped and Flush-fit. The Flush-fit type is recommended for vacuum services. The inner lip minimizes turbulence in high-velocity applications
