The GRACO 164672 is a threaded adapter designed to connect components with 1/4 inch NPSM (National Pipe Straight Mechanical) and 3/8 inch NPT (National Pipe Taper) threads. It is typically constructed from durable metal for reliable use in fluid handling systems, facilitating secure connections between different pipe sizes or equipment within GRACO sprayers and related machinery.

Key Features:

• Threaded adapter
• 1/4 NPSM x 3/8 NPT
• Compatible with GRACO sprayers and equipment requiring 1/4 NPSM to 3/8 NPT thread conversion
• Facilitates secure and leak-free connections
• Durable construction for repeated use
• Standardized thread sizes for easy integration

Applications:
Used in GRACO sprayer systems to connect hoses, pumps, or other components with differing thread sizes, ensuring proper fluid transfer and system integrity.

Installation Notes:

• Using genuine GRACO adapters ensures proper fit, leak prevention, and system reliability. Non-genuine parts may compromise performance and safety.
• Ensure threads are clean and free from debris before installation
• Apply appropriate thread sealant if required by the application
• Hand-tighten before using a wrench to avoid cross-threading
• Check for leaks after installation and during operation
• Inspect adapter regularly for signs of wear or damage
• Replace if threads are stripped or if leaks are detected
• Follow manufacturer guidelines for maintenance intervals
