The GRACO 17Y904 is a recirculation manifold designed for use in spray foam and fluid handling equipment. It is typically constructed from durable materials suitable for high-pressure fluid applications, though the specific material is not specified. Its primary function is to facilitate the recirculation of fluids within GRACO equipment, allowing for rapid preheating and efficient system priming.

Key Features:

• Recirculation Manifold
• 17Y904
• Compatible with GRACO spray foam and fluid handling systems (e.g., ProPAK 200S, Reactor 3 E-20 Standard)
• Facilitates rapid preheating of hoses and system priming
• Designed for reliable operation in high-pressure environments
• Ease of maintenance and installation

Applications:
Used in spray foam insulation rigs and other GRACO fluid handling systems to recirculate fluids for preheating and priming, ensuring optimal system performance and reducing downtime.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in high-pressure fluid applications.
• Connect high-pressure, moisture-resistant recirculation lines to the manifold and route them back to the respective supply drums.
• Ensure all valves in the fluid circuit are open during installation.
• Follow equipment manual instructions for loading fluid and setting temperature targets.
• After reaching temperature targets, close fluid valves and remove the recirculation manifold as per manual instructions.
• To prevent air from reacting with isocyanate, attach the block to the recirculation manifold after removal.
• Do not cross-contaminate fluids when recirculating; always recirculate component A to the component A drum and component B to the component B drum.
• Use hoses rated for the maximum working pressure of the equipment.
• Regularly inspect and maintain the manifold and associated hoses for wear and leaks.
