Tough forged brass body and bonnet are designed for years of on-the-job service and provide durability for service in corrosive atmospheres.  Heavy duty construction provides long trouble-free operation; brass bonnet features colorcoded label for easy gas identification.  Reverse flow check valves are installed on oxygen and fuel gas cylinder regulators to protect against reverse flow of gases.  The oxygen (Item 12-4014) and acetylene (Item 12-4016) regulators come with Hard Hat™ Gauge Guard which helps prevent broken gauges which can lead to gas leaks, costly repairs and expensive down time.  Replacement Gauges also available (see chart). Our Replacement Gauges can be used with other brands of regulators.
