The GRACO 21694-25 is a material hose assembly with a 1/2" internal diameter, designed for use in GRACO equipment to transfer materials such as polyester resin and gel-coat in RTM (Resin Transfer Molding) injection systems. It is a critical component for ensuring safe and efficient material flow between the pump and application point.

Key Features:

• Material hose assembly
• 1/2" ID
• Compatible with GRACO RTM injection systems (e.g., Spartan, Spartan 2, Spartan 3) for use with polyester resin and gel-coat
• Designed for reliable material transfer in high-pressure injection systems
• Integral part of the material recirculation and application circuit
• Supports consistent operation and maintenance of GRACO equipment

Applications:
Used in GRACO RTM injection systems for transferring polyester resin and gel-coat in composite manufacturing, mold filling, and similar industrial applications.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, safety, and optimal performance of the equipment.
• Ensure all connections are secure and leak-free before operation
• Follow the equipment manual for specific installation and maintenance procedures
• Regularly inspect the hose for wear, damage, or leaks and replace as necessary
