One-bolt coupling

Issue 6 2022 Fire & Safety

Johnson Controls has announced the next-generation Grinnell G-Fire One-Bolt Figure 579A coupling with customised gaskets for more secure fitting on fire suppression pipe joints. The grooved, rigid coupling is ready to connect right out of the box, providing contractors with a fast and smooth installation experience.

“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 for product management, Johnson Controls. “We’ve improved this next-generation coupling with customised gaskets so contractors can simply position the coupling and tighten a single bolt.”

In addition to speeding up installation, the One-Bolt 579A coupling features centre-stop gaskets customised 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 optimise 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.
