The GRACO V-51205K322 is a stainless steel (316) reducer fitting designed to connect 3/4-inch NPT (National Pipe Thread) to 1/4-inch NPT pipe threads. It is intended for use in fluid handling systems, including those found in GRACO spray equipment, to adapt between different pipe sizes while maintaining a secure, leak-resistant connection.

Key Features:

• Reducer fitting
• 3/4NPT x 1/4NPT
• Stainless steel (316)
• 4K (likely refers to 4,000 psi rating, but confirm with manufacturer)
• Compatible with GRACO fluid handling systems and other equipment requiring 3/4NPT to 1/4NPT adapters
• Female-male (FM) thread configuration; corrosion-resistant 316 stainless steel construction for durability and reliability in harsh environments

Applications:
Used in fluid transfer and spray equipment systems where pipe size reduction is required, such as in paint sprayers, lubrication systems, and industrial fluid handling applications.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and safety in high-pressure fluid systems.
• Ensure threads are clean and properly lubricated before installation. Hand-tighten first, then use appropriate tools to achieve a secure, leak-free connection. Do not overtighten to avoid damaging threads.
• Regularly inspect for leaks or wear. Replace if signs of corrosion or damage are present. Always use thread sealant compatible with the application and material.
