The GRACO 123073 is a hex nipple fitting designed to connect two pipe sections with different National Pipe Thread (NPT) sizes—1 inch NPT on one end and 3/4 inch NPT on the other. The fitting is typically made from metal (exact material not specified in available sources) and is intended for use in fluid handling systems within GRACO equipment, facilitating secure and leak-resistant connections between components of varying sizes.

Key Features:

• Hex nipple fitting
• 1NPT x 3/4NPT
• Compatible with GRACO equipment requiring 1 inch to 3/4 inch NPT transitions
• Hex design for easy installation and removal with standard tools
• Reliable, leak-resistant connection
• Durable construction for industrial environments

Applications:
Used in fluid handling and transfer systems, particularly in industrial and maintenance equipment where secure, leak-resistant connections between different pipe sizes are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape for leak prevention
• Tighten securely using a wrench on the hex portion to avoid damage to the fitting
