The GRACO 117728 is a compression union fitting designed for use in fluid handling systems. It is typically constructed from durable materials such as brass or similar alloys, ensuring reliable connections in high-pressure environments. This part is intended to securely join two sections of tubing or hose within GRACO spray equipment, maintaining system integrity and preventing leaks.

Key Features:

• Compression union fitting
• 3/8 inch
• Brass or similar alloy (not explicitly specified, but typical for this type of fitting)
• Compatible with GRACO spray equipment requiring 3/8 inch compression fittings
• Ensures secure, leak-free connections
• Easy to install and maintain
• Designed for reliability and repeated use in demanding environments

Applications:
Used in GRACO spray systems for joining tubing or hose sections, commonly found in paint, texture, and fluid transfer applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and safety within GRACO equipment.
• Ensure tubing ends are clean and free from burrs before installation
• Tighten compression nut securely but avoid over-tightening to prevent damage
• Check for leaks after installation and during routine maintenance
• Regularly inspect fittings for wear or damage
• Replace fittings at the first sign of leakage or degradation
• Follow GRACO equipment manual for specific installation instructions
