The GRACO 15A990 is a heater gasket designed for use in high-pressure fluid heaters, such as the Viscon HF series. It is a sealing component, typically made from durable, heat-resistant materials, intended to ensure a leak-free connection between heater components under high pressure and temperature conditions.

Key Features:

• Heater gasket
• 15A990
• Compatible with GRACO Viscon HF high-pressure fluid heaters (e.g., models 3A2954A, 3A2954R, 309524T)
• Seals high-pressure, high-temperature fluid connections
• Essential for leak prevention and equipment reliability
• Designed for easy replacement and maintenance

Applications:
Used in high-pressure fluid heating systems for variable heating of viscous fluids, commonly found in industrial and professional fluid handling applications.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and safety, especially under high pressure and temperature conditions.
• Always follow the equipment manual for installation procedures.
• Inspect the gasket for damage before installation.
• Ensure surfaces are clean and free of debris before fitting the gasket.
• Tighten fasteners evenly to avoid distortion or leaks.
• Regularly inspect gaskets for wear or degradation.
• Replace gaskets at recommended intervals or if leaks are detected.
• Use only GRACO-approved replacement parts for optimal performance.
