The GRACO 121908 is a stainless steel fitting adapter designed to connect components with 3/8-inch NPT (National Pipe Thread) and 1/4-inch NPSM (National Pipe Straight Mechanical) threads. It is intended for use in GRACO fluid handling and lubrication equipment to ensure secure, leak-free connections between different thread types.

Key Features:

• Adapter/Fitting
• 3/8NPT x 1/4NPSM
• Stainless Steel
• Compatible with GRACO equipment requiring 3/8NPT to 1/4NPSM thread conversion
• Durable stainless steel construction for corrosion resistance
• Reliable connection between different thread standards
• Designed for use in demanding industrial environments

Applications:
Used in fluid transfer, lubrication, and spray systems where secure, leak-free connections between 3/8NPT and 1/4NPSM threaded components are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of your equipment.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant if required for the application
• Hand-tighten and then use a wrench to secure, avoiding over-tightening to prevent thread damage
• Regularly inspect for leaks or signs of wear
• Replace if damaged or if leaks are detected
