Johnson Controls has announced that it 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 allow contractors to perform easy and quick installations on smaller diameter piping and in tight spaces.

GRINNELL G-Fire One-Bolt

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 David (Dave) Nelligan, Global Product Manager at Johnson Controls.

Dave adds, “By adding these two new sizes, our customers can now have a complete range of One-Bolt couplings where speed matters most.

Fast and easy push-on installation

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.

The GRINNELL G-Fire One-Bolt couplings feature 360-degree contact for an exceptionally rigid joint and a grooved, rigid coupling design to make joining pipe much faster and easier.

UL/ULC Listed and FM Approved

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

The couplings also have a single-bolt design that cuts out alternate tightening, thereby providing for seamless installation and efficient product performance.
