“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 Martin Schulte-Frankenfeld, global director 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. The 1.25- and 1.5-inch coupling sizes keep their proven, powder-lubricated gasket, ideal for small pipe diameters, while 2- through 4-inch sizes use a redesigned self-lubricating gasket intended to optimize protection against rolls or pinches. A low-profile spine allows contractors to install couplings in tighter spaces, while 360-degree pipe contact ensures a truly rigid joint.

Pre-assembled 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 assists in more consistent installations and dependable product performance. The coupling has a pressure rating of up to 365 psi and is UL/ULC Listed, FM Approved, VdS Approved and LPCB Approved.
