The GRACO 521079 is a compression spring designed for use in GRACO equipment, specifically as a replacement spring for certain regulator assemblies. Its material is not explicitly stated, but it is engineered for durability and consistent performance in industrial fluid handling systems. The spring is intended to allow regulated pressure adjustments within GRACO pumps and regulators.

Key Features:

• Compression spring
• 521079
• Allows regulated pressure from 400 to 1000 psi (28 to 69 bar; 2.8 to 7 MPa) when used as a replacement in specific GRACO regulators
• Replaces spring in 903958 regulator to enable low-range pressure regulation
• Engineered for consistent performance
• Durable construction for industrial environments
• Ease of replacement and maintenance

Applications:
Used in GRACO pumps and regulators for precise pressure control in fluid handling systems, suitable for industrial and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure equipment is depressurized before installation
• Follow manufacturer guidelines for spring replacement
• Inspect spring and regulator for wear or damage before installation
• Consult equipment manual for specific installation procedures
• Regularly inspect and maintain regulator assemblies
• Replace springs as part of routine maintenance to ensure consistent pressure regulation
