The GRACO 556636 is a male branch tee fitting designed to connect 5/16 inch (7.94 mm) tubing to a 1/8 inch (3.2 mm) NPTF (National Pipe Thread Fuel) port. Constructed from brass, this fitting is used to branch or split fluid lines in GRACO lubrication and fluid handling equipment, ensuring secure and leak-resistant connections.

Key Features:

• Male Branch Tee
• 5/16 inch (7.94 mm) Tube x 1/8 inch (3.2 mm) NPTF
• Brass
• Maximum working pressure: 2500 psi (17.2 MPa, 172 bar) (varies by source; some manuals list lower pressures for specific equipment, e.g., 150 psi for certain systems)
• Compatible with 5/16 inch tubing and 1/8 inch NPTF threaded ports in GRACO lubrication and fluid handling systems
• Durable brass construction for corrosion resistance
• Designed for secure, leak-resistant connections
• Suitable for high-pressure applications (up to 2500 psi in some configurations)

Applications:
Used in GRACO lubrication systems, chassis lubrication, and other fluid handling equipment where branching or splitting of fluid lines is required. Commonly found in industrial, mining, and agricultural maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system. Non-genuine parts may compromise system integrity and safety.
• Ensure tubing and threads are clean and free from debris before installation
• Use appropriate tools to tighten fittings to avoid over-torquing or damaging threads
• Check for leaks after installation and during routine maintenance
• Follow manufacturer guidelines for maximum working pressure and temperature limits
