The Johnson Controls GRINNELL G-Fire One-Bolt Coupling features a single-bolt design that eliminates alternate tightening and helps contractors perform quicker, more consistent installations with dependable product performance. The one-bolt coupling is pre-lubricated and preassembled for fast push-on installation in both vertical and horizontal applications. It features 360-degree contact for an exceptionally rigid joint; a low-profile spine allows installation in tighter spaces. The coupling’s center-stop gasket ensures proper positioning on the pipe. The one-bolt coupling is UL/ULC-listed and FM-approved with a pressure rating up to 365 psi. It is available in 2” to 8” sizes and both painted and galvanized finishes.
