The GRACO 16C399 is a stainless steel adapter fitting designed to connect 3/8-inch NPT (National Pipe Thread) to 08 JIC (Joint Industry Council) hydraulic connections. It is engineered for use within GRACO fluid handling and dispensing equipment, providing a reliable and corrosion-resistant interface for high-pressure fluid transfer.

Key Features:

• Adapter fitting
• 3/8 NPT x 08 JIC
• Stainless steel
• 6K (6000 psi working pressure)
• Compatible with GRACO fluid handling and dispensing systems requiring 3/8 NPT to 08 JIC connections
• Corrosion-resistant stainless steel construction
• High-pressure capability (up to 6000 psi)
• Reliable sealing for fluid transfer
• Durable for industrial environments

Applications:
Used in industrial fluid handling, lubrication, and dispensing systems where secure, high-pressure connections between 3/8 NPT and 08 JIC fittings are required.

Installation Notes:

• Using genuine GRACO fittings ensures compatibility, reliability, and safety in high-pressure applications, reducing the risk of leaks and equipment failure.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant or tape as recommended for the application
• Tighten to manufacturer’s torque specifications to prevent over-tightening or leaks
• Inspect for leaks after installation and during routine maintenance
• Regularly inspect fittings for signs of wear, corrosion, or leaks
• Replace fittings if damage or degradation is detected
• Follow GRACO equipment maintenance schedules
