The GRACO 16A990 is a coupling designed to connect a 1/4 inch inside diameter hose to a 3/8 inch NSPM (National Standard Pipe Straight Mechanical) fitting. Its material is not explicitly specified in available documentation, but similar GRACO couplings are typically constructed from durable metals or alloys for reliable fluid transfer. This part is intended for use within GRACO fluid handling equipment to ensure secure and leak-free connections between hoses and fittings.

Key Features:

• Coupling
• 1/4 Hose ID x 3/8" NSPM
• Designed for GRACO fluid handling equipment and compatible with 1/4" ID hose and 3/8" NSPM fittings
• Secure connection between hose and fitting
• Designed for reliable fluid transfer
• Compact and robust design for industrial environments

Applications:
Used in fluid transfer systems within GRACO equipment, suitable for applications requiring secure hose-to-fitting connections in industrial, maintenance, and lubrication systems.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment. Non-genuine parts may compromise system integrity and safety.
• Ensure both hose and fitting are clean and free from debris before installation
• Hand-tighten the coupling, then use appropriate tools to secure without over-tightening
• Inspect for leaks after installation and during routine maintenance
• Regularly inspect couplings for wear or damage
• Replace at first sign of leakage or degradation
• Follow GRACO equipment manual for specific installation and maintenance procedures
