Next-generation Grinnell One-Bolt Coupling
Next-generation Grinnell One-Bolt Coupling features customized gaskets for faster and easier joining of fire suppression piping
- The new G-Fire One-Bolt Figure 579A is a grooved, rigid coupling ready for out-of-the-box, push-on installation
- The 2- through 4-inch couplings use redesigned, self-lubricating gaskets for the smoothest possible installation experience
- Gaskets are customized to coupling sizes to prevent rolls and pinches for a truly secure, rigid joint
MILWAUKEE – (July 6, 2022) – Johnson Controls, the global leader for smart, healthy, and sustainable buildings, launches the next-generation Grinnell G-Fire One-Bolt Figure 579A Coupling with customized gaskets. The grooved, rigid coupling is ready to connect right out of the box, providing contractors with the smoothest possible installation experience. The 579A Coupling expands the G-Fire One-Bolt Coupling family and makes joining fire suppression system piping faster and easier than ever before.
“Whether contractors are installing a fire sprinkler system in a storage facility or standard commercial space, their time is valuable. Joining pipe shouldn’t be time consuming or laborious,” said Anna Khanova, global VP product management, Johnson Controls. “We’ve improved this next-generation coupling with customized gaskets so contractors can simply position the coupling and tighten a single bolt. We’re excited to offer such a time-saving addition to our One-Bolt Coupling portfolio that gives contractors more confidence in their fire suppression system installations.
In addition to speeding up installation, the One-Bolt 579A Coupling features center-stop gaskets customized to specific coupling sizes to help ensure proper positioning and protect against rolls and pinches. The 1.25- and 1.5-inch coupling sizes use a proven, powder-lubricated gasket, while 2- through 4-inch sizes use a redesigned self-lubricating gasket. A low-profile spine allows contractors to install couplings in tighter spaces, while 360-degree pipe contact ensures a truly rigid joint.
Preassembled and pre-lubricated, the 579A Coupling features an innovative, three-piece housing and just one bolt to tighten. The coupling’s single-bolt design eliminates alternate tightening and results in more consistent installations and dependable product performance. The couplings have a pressure rating of up to 365 psi and are UL/ULC Listed, FM Approved, VdS Approved and LPCB Approved.
