FLEXIBLE CONNECTORS
SINGLE SPHERE
FLEXIBLE CONNECTOR
Flexible connectors are used to absorb thermal and seismic
movement, absorb hydraulic shock, provide vibration and
noise dampening, ease installation and correct minor
misalignment of piping and components. They come
in a variety of sizes, materials, and connection ends for
numerous applications.
Similar to the metal exible connectors in application
advantages, single sphere exible connectors are suitable
for pressure and vacuum services. The spherical shape
is stronger than cylindrical elastomer connectors and
disperses pressure evenly over a larger surface area. The
streamline shape also reduces turbulence and sediment
build-up and lessens deformation while under pressure. The
elastomer allows greater movements in the axial, elongation,
lateral, and angular directions and provides a wide service
range due to its chemical resistance characteristics.
