The GRACO 257717 is a restrictor orifice assembly designed to control fluid flow within GRACO dispensing equipment. It is typically constructed from durable materials suitable for high-pressure applications and is intended for use in systems handling polyol and isocyanate materials. The part is used to regulate flow and maintain system pressure in professional, indoor environments.

Key Features:

• Restrictor, Orifice Assembly
• 0.039 (inch orifice size)
• Up to 3000 psi (21 MPa, 207 bar) Maximum Fluid Working Pressure (based on system compatibility)
• Designed for use with GRACO GX-16 and similar dispensing systems for polyol and isocyanate materials
• Precision orifice for accurate flow control
• Includes O-rings and cleanout drill bits for maintenance
• Reliable performance in high-pressure environments
• Ease of maintenance and replacement

Applications:
Used in GRACO dispensing equipment for professional, indoor applications involving polyol and isocyanate materials. Not for use in explosive atmospheres or outdoor environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains system safety and performance.
• Ensure the system is depressurized before installation or maintenance
• Use included O-rings and cleanout drill bits for proper assembly and maintenance
• Follow all safety and installation instructions in the equipment manual
• Inspect for leaks and proper fit after installation
