The GRACO 257779 is a double nitrogen blanket harness designed for use with GRACO tank feed systems. It is intended to provide a nitrogen blanket over material in tanks, helping to prevent oxidation and contamination. The material is not specified in available documentation, but it is engineered for professional use in industrial environments.

Key Features:

• Nitrogen Blanket Harness
• Double
• 100 psi (0.7 MPa, 7.0 bar) Maximum Working Pressure (for associated tank feed systems)
• For use with GRACO HFR™ and HVR™ plural-component proportioners and compatible tank feed systems
• Designed for dual-tank applications
• Includes insulation blanket and warning label
• Engineered for reliability and ease of maintenance in industrial settings

Applications:
Used in industrial tank feed systems to supply material to plural-component proportioners, particularly in applications requiring inert gas blanketing to protect sensitive materials from oxidation and contamination.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, safety, and optimal performance of the tank feed system.
• Follow all safety instructions and warnings provided in the GRACO manual.
• Ensure proper connection and secure mounting of the harness.
• Regularly inspect for wear and proper function.
• Refer to the manual for specific installation steps and maintenance schedules.
