The GRACO 19B728 is a cylinder regulator designed for medium pressure applications, specifically as a back pressure regulator with a 10:1 ratio. It is intended to regulate fluid pressure within GRACO equipment, ensuring consistent and optimal system performance. The material is not explicitly specified in available documentation, but similar GRACO regulators often use robust metals and engineered plastics for durability. Its primary function is to maintain the required pressure for smooth and efficient operation of fluid handling systems.

Key Features:

• Back Pressure Regulator, Medium Pressure
• 19B728 (10:1)
• Regulated range: 100–1000 psi (7–70 bar) for 10:1 model
• Designed for use with GRACO medium pressure fluid systems

Applications:
Used in industrial and commercial fluid handling systems where precise medium pressure regulation is required, such as lubrication, paint, and chemical transfer applications.

Installation Notes:

• Using genuine GRACO parts like the 19B728 ensures proper fit, function, and reliability, reducing downtime and maintenance costs.
• Always use thread sealant on connections as recommended by GRACO
• Torque connections to 60–70 ft-lbs (81–95 N•m) for secure installation
• Refer to the equipment manual for specific installation and maintenance procedures
• Regularly inspect for leaks and wear
• Replace with genuine parts to maintain system integrity
• Follow manufacturer guidelines for maintenance intervals
