The Viking C3F Lightweight Flexible Coupling installs directly into commercial and industrial fire sprinkler piping assemblies. Its flexible design accommodates pipe movement, vibration, and minor misalignments, which reduces operational stress across the network and protects against mechanical failure.

Built to satisfy stringent life safety regulations, this component complies with recognized NFPA standards for fire protection installations. It carries both UL Listing and FM Approved credentials, satisfying third-party testing requirements for commercial plumbing and early suppression fire distribution systems.

  • Ductile Iron Construction: High-strength material withstands heavy operational stresses in demanding environments.

  • Flexible Movement: Absorbs network vibration and handles pipe misalignment to extend overall system longevity.
  • Grooved Compatibility: Integrates seamlessly with standard grooved pipe networks without requiring custom modifications.
  • Lightweight Build: Simplifies handling on the job site for faster, more efficient installations.
