Grooved coupling and fitting
he GRINNELL Rapid Installation Pivot-bolt (GRIP) Figure 740 Coupling technology joins pipe ten times faster than traditional methods and two times faster than standard grooved coupling and fitting without losing the ability to properly inspect the gasket seal. The GRIP Coupling is a more efficient, reliable way to join pipe. There are no loose components and only one bolt to tighten, meaning installation is quick and easy. The coupling features an EHT push-on style gasket that allows the installer to visually inspect for a proper seal.
