Designed for carbon dioxide service, this UL-listed regulator features one pressure regulator and one outlet, with 50 mm plastic gauges and a red/green contents gauge for quick supply checks. A tamper-proof screw and cap help prevent unauthorized adjustment, while a check valve on the outlet helps prevent liquid product backflow. Its one-piece encapsulated seat and internal filter protect the PTFE seat from particulate contamination, and a sensitive neoprene diaphragm supports improved pressure control. The regulator has a brass body and black-plated zinc bonnet.
