The GRACO 183883 Plunger Spring is a replacement part designed for use in GRACO fluid pressure regulators and related equipment. It is a small, precision-engineered spring that assists in the movement and positioning of the plunger within the regulator assembly. The material is not explicitly specified, but typical GRACO springs are made from high-grade steel for durability and consistent performance. Its intended function is to ensure smooth, reliable operation of the plunger mechanism in fluid regulation systems.

Key Features:

• Plunger Spring
• 1.2 x 1.2 x 1.2 inches
• Designed for GRACO fluid pressure regulators and related equipment (e.g., part of assembly in GRACO 307886L Fluid Pressure Regulator)
• Precision-engineered for consistent performance
• Compact size for easy integration into regulator assemblies
• Reliable operation in demanding industrial environments

Applications:
Used in GRACO fluid pressure regulators and similar equipment for precise fluid control in industrial, lubrication, and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system reliability and void warranties.
• Always refer to the specific GRACO equipment manual for installation instructions.
• Ensure the regulator is depressurized before replacing the spring.
• Inspect the plunger and surrounding components for wear or damage during replacement.
• Use appropriate tools and follow torque specifications for reassembly (e.g., 30–35 ft-lb for related regulator components).
• Lubricate threaded parts with an appropriate lubricant when reassembling.
