Viking Fireking™ Flexible Coupling (VK-FC)
Flexible grooved coupling for connections subject to movement, vibration, and thermal variations.
VIKING Fireking™ Reducing Tee – Grooved (VK-RTG)
- The VIKING Fireking™ VK-RTG Grooved Reducing Tee allows efficient branching from a larger main pipe to a smaller outlet while maintaining mechanical integrity and hydraulic performance. Its grooved ends enable rapid installation and easy system modification.
- Nominal Sizes: 2" × 1" to 12" × 10" (DN50 × DN25 to DN300 × DN250)
- Working Pressure: 12.1 bar (175 psi) up to 34.5 bar (500 psi), size dependent
- Material: Ductile Cast Iron, ASTM A536 Grade 65-45-12
- Connection Type: Grooved × Grooved × Grooved
- Enables efficient transition from main lines to branch circuits
- Reduces system material cost by optimizing pipe sizing
- Eliminates field-fabricated reducers and tees
- Maintains high pressure and fire-system integrity
- Suitable for future system expansion
- Fire sprinkler systems where branch lines require smaller diameters than the main distribution pipe, including floor branches and zone take-offs.
- UL Listed
- FM Approved
