• Optimized for dynamic environments with frequent pressure changes and rapid cycling.

Technical Specifications

Performance Benefits

• Delivers stable force under frequent cycling, reducing drift and maintaining calibration.
• Extends component life by absorbing shock and preventing rapid fatigue of adjacent parts.
• Helps maintain accurate pressure control and fluid delivery in finishing equipment.
• Ideal for industrial environments where reliability and precision are essential.

Installation & Maintenance Advice

• Verify correct spring orientation and preload during installation to ensure proper operation.
• Confirm seating surfaces are clean and free of debris or damage before final assembly.
• Track operational cycles and replace the spring when compression set or fatigue becomes evident.
• Ensure system design permits proper spring travel and avoid over-compression which reduces life.

Conclusion

The Graco 105291 Compression Spring is an essential precision component in high-performance spray and fluid control systems. Its durable construction, accurate force characteristics and compatibility with demanding applications make it a reliable choice for enhancing system stability, reducing downtime and maintaining operational consistency in professional coating and fluid delivery equipment.
