The GRACO 15U368 is a cap nut designed to fit and secure components within GRACO spray equipment. Its material is not explicitly specified in available sources, but it is engineered for reliable sealing and fastening in high-pressure fluid handling systems. The part is intended to ensure steady functionality and leak-free operation in GRACO spray applicators.

Key Features:

• Cap Nut
• 1/4-18 NPSM
• Designed for GRACO spray equipment, especially models referenced in GRACO manuals (e.g., Free Flow Applicator models 24B327, 17Z128)
• Engineered for secure fit and leak prevention
• Original GRACO part for optimal compatibility and reliability
• Easy to install and maintain

Applications:
Used in GRACO spray equipment for sealing and securing fluid connections, particularly in portable spray applicators for water-based and solvent-based materials (with compatible seals and hoses).

Installation Notes:

• Using genuine GRACO parts like the 15U368 ensures proper fit, leak prevention, and equipment reliability. Non-genuine parts may compromise safety and performance.
• Ensure threads are clean and undamaged before installation
• Hand-tighten the nut to avoid over-torquing and thread damage
• Check for leaks after installation and during operation
• Refer to the GRACO equipment manual for specific installation procedures
• Regularly inspect the nut for wear or damage
• Replace if signs of corrosion or thread damage are present
• Use only GRACO-approved parts for replacements
