The GRACO 257709 is a restrictor orifice assembly designed to control and regulate fluid flow within GRACO equipment. It is typically used in lubrication and fluid handling systems to ensure precise metering and distribution. The material is not specified in available sources, but such assemblies are commonly made from durable metals or engineered plastics for longevity and chemical resistance. Its intended use is to maintain consistent flow rates and protect downstream components from excessive pressure or flow.

Key Features:

• Restrictor, Orifice Assembly
• 257709, .025 (likely refers to orifice diameter in inches)
• Designed for use with GRACO lubrication and fluid handling equipment; specific compatibility should be confirmed with equipment manuals or GRACO specialists
• Precision flow control
• Reliable performance in demanding environments
• Ease of maintenance and replacement

Applications:
Used in industrial lubrication systems, fluid dispensing, and maintenance applications where controlled flow is critical. Suitable for mining, agriculture, manufacturing, and other sectors requiring reliable fluid management.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment. Non-genuine parts may compromise system integrity and void warranties.
• Ensure the system is depressurized before installation
• Inspect the orifice for debris or damage prior to installation
• Follow GRACO equipment manual instructions for specific installation procedures
• Regularly inspect and replace the orifice assembly as part of routine maintenance to prevent clogging and ensure consistent flow
