37BG01 is a Justrite® safety snap cap for gas cylinders with low pressure-coarse threads. These safety snap caps are designed to reduce potential accidents and theft of gas cylinders. These safety snap caps can fit atop most North American gas cylinders, which restricts access to the main cylinder control and regulator attachment that prevents unauthorized use. To use, simply mount the cap to the cylinder and attach the regulator, close cap and attach a padlock. The design allows access to the valve without having to remove the cap and replace the regulator each time. It has a welded steel construction with a powder coat finish that provides chemical resistance.
