In the ever-evolving world of fire protection, trustworthy system performance and efficient installation practices aren’t just important… they’re non-negotiable. Every minute saved on the job site, every component that reduces complexity, and every design that removes guesswork contributes to safer buildings and smoother inspections. That’s exactly why Viking’s newest innovation — the VK970 Quick Response Sprinkler and Flexible Hose Assembly — is such a significant step forward for contractors, designers, and AHJs alike.
This cULus Listed, all-in-one fire sprinkler solution is purpose-built to eliminate one of the most time-consuming challenges in system design and installation: hydraulic recalculations. Thoughtfully engineered for real-world applications and built to Viking’s stringent quality standards, the VK970 is more than just a part number on a spec sheet; it’s a dependable, ready-to-go tool for your most demanding jobs.
Why the VK970 Is a Big Deal
At the heart of the VK970 assembly are two essential components: a factory-installed quick response sprinkler and a flexible braided hose, both designed to work seamlessly together. The standout feature? A pre-calibrated K-factor of 5.6 (80.6 metric), which eliminates the need to apply equivalent length adjustments during hydraulic calculations. That means there’s no estimation, no recalculating friction loss, and no time wasted looking for missing system data.
For contractors working on retrofits, where system drawings may be outdated or nonexistent, the VK970 offers a rare advantage: a dependable, code-compliant solution that speeds up installation and reduces margin for error. And on new installations, it simplifies the design process and ensures consistency across the job.
“This cutting-edge offering streamlines the installation process and reduces the burden of complex hydraulic calculations,” says Martin Workman, Senior Vice President – Product Experience at Viking Group, Inc. “Our commitment to innovation and quality is reflected in every aspect of the product’s design, from its robust manufacturing to its versatile application.”
Designed for the Realities of the Jobsite
Flexibility in the field can mean the difference between a smooth install and a frustrating one. The VK970 is offered in two common lengths: 48 inches and 60 inches. This makes it adaptable to a wide range of ceiling types, structural obstructions, and room layouts. Each hose is constructed with 304 stainless steel and is fully welded to ensure durability over the long term.
With a UL Listed 2-inch minimum bend radius, the hose supports up to four bends without any need for additional tools or supports. That’s a major time-saver for installers working in tight ceiling spaces or around existing infrastructure. And because it’s shipped in packs of five, each complete with recessed escutcheons (Model NP-1 or NP-2), contractors can streamline staging and protect components from damage between the warehouse and the jobsite.
The sprinkler itself is permanently affixed to the hose assembly — a feature that ensures product integrity and eliminates compatibility concerns. Temperature ratings include 135°F, 155°F, 175°F, 200°F, and 286°F, with color-coded glass bulbs for quick visual identification. This range makes the VK970 suitable for a variety of commercial and industrial applications, including areas with elevated ambient temperatures.
A Finish for Every Environment
Because aesthetics and corrosion resistance matter, especially in exposed applications, the VK970 is available in a variety of finishes, including:
- Traditional brass
- Traditional chrome
- White or black polyester coatings
- A corrosion-resistant electroless nickel PTFE (ENT) finish
Whether you’re working in a retail environment, data center, or utility space, there’s a VK970 finish and temperature rating that fits.
