Johnson Controls is expanding its GRINNELL G-Fire One-Bolt coupling product line by adding two new sizes: 1.25 and 1.5 inches. The new, smaller couplings will reportedly allow contractors to perform quicker installations on smaller diameter piping and in tight spaces. As part of the One-Bolt family, both couplings feature the unique, single-bolt design that eliminates alternate tightening while resulting in more consistent installations and dependable product performance.

“First launched in 2018, our GRINNELL One-Bolt coupling product line now offers more choices for contractors working on a wide variety of projects, from storage facilities to standard commercial projects,” said Dave Nelligan, global product manager at Johnson Controls. “By adding these two new sizes, our customers can now have a complete range of One-Bolt couplings where speed matters most.”

The One-Bolt couplings allow fast and easy push-on installation thanks to a pre-lubricated gasket and pre-assembled design. The couplings can be used in both vertical and horizontal applications across wet, dry and freezer systems. They feature 360-degree contact for an exceptionally rigid joint and a grooved, rigid coupling design to make joining pipe faster and easier.

A low-profile spine allows for installation in tighter spaces and a centre-stop gasket ensures proper positioning on pipe. The couplings are UL/ULC Listed and FM Approved, with a pressure rating of up to 365 psi.
