The GRACO 501511 is a helical compression spring designed for use in GRACO fluid regulators, specifically recommended for the 0–1000 psi (0–7 MPa, 0–70 bar) pressure range. It is a standard component in certain GRACO regulator models and is intended to provide consistent force and reliable operation within fluid handling systems.

Key Features:

• Helical compression spring
• 501511
• Recommended for 0–1000 psi (0–7 MPa, 0–70 bar) range
• Standard on GRACO Model 217576 fluid regulator; may be used in other compatible GRACO equipment
• Provides consistent force for pressure regulation
• Reliable performance in fluid handling systems
• Easy to replace as part of routine maintenance

Applications:
Used in GRACO fluid regulators for pressure regulation in industrial fluid handling systems, including lubrication, paint, and other fluid transfer applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure the regulator is depressurized before replacing the spring
• Follow GRACO equipment manual instructions for disassembly and reassembly
• Inspect the spring for wear or damage during routine maintenance
• Use only GRACO-approved replacement parts
• Regularly inspect and maintain fluid handling systems
• Consult GRACO documentation for specific installation procedures
