The GRACO 190401 is a pipe adapter designed to connect components with differing thread sizes—specifically, 1" NPT (male or female, depending on product documentation) to 1 1/2" NPT (male or female, depending on product documentation). The material is typically steel or brass, but for this specific part, the material is not specified in available sources. Its intended use is to facilitate secure and leak-free connections between pipes or fittings in GRACO fluid handling equipment.

Key Features:

• Pipe adapter
• 1" NPT x 1 1/2" NPT
• Designed for use with GRACO fluid handling equipment requiring connection between 1" NPT and 1 1/2" NPT fittings
• Facilitates secure and leak-free connections
• Enables compatibility between different pipe sizes

Applications:
Used in fluid transfer and lubrication systems where adapters are required to connect pipes or fittings of different sizes. Commonly found in industrial, mining, and agricultural equipment maintenance and installation.

Installation Notes:

• Using genuine GRACO adapters ensures proper fit, leak prevention, and system reliability. Non-genuine parts may compromise system integrity and safety.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant or tape to prevent leaks
• Hand-tighten before using a wrench to avoid cross-threading
• Check for leaks after installation and during system operation
• Regularly inspect adapters for wear or damage
• Replace adapters if signs of corrosion or thread damage are present
• Follow manufacturer torque specifications if available
