The GRACO 188271 is a seal housing component designed for use in GRACO fluid-handling systems. Its material is not explicitly specified in available documentation, but it is typically constructed from durable engineering plastics or metals to withstand the demands of industrial fluid dispensing. The part is intended to house and protect the needle shaft seal within metering valve assemblies, ensuring reliable operation and preventing leaks.

Key Features:

• Seal Housing
• Compatible with GRACO metering valve assemblies, such as those referenced in PrecisionFlo Metering Valve Upgrade documentation
• Designed for secure fit and protection of needle shaft seals
• Supports reliable operation in high-demand fluid dispensing applications
• Ease of maintenance and replacement as part of valve repair kits

Applications:
Used in industrial fluid dispensing systems, particularly in metering valve assemblies for precise control of fluid flow in lubrication, painting, and other fluid-handling applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment. Non-genuine parts may compromise system integrity and safety.
• Ensure the system is depressurized before installation or maintenance
• Follow the manufacturer’s assembly instructions for the specific valve or metering system
• Inspect the seal housing and surrounding components for wear or damage during installation
• Refer to the equipment manual for torque specifications and proper alignment
• Regularly inspect the seal housing for signs of wear or leakage
• Replace the seal housing as part of scheduled maintenance or when damage is detected
• Use only GRACO-approved replacement parts for repairs
