The GRACO 156172 is a swivel union fitting designed for connecting hoses or pipes in fluid handling systems. Its material is not specified in available sources, but it is engineered for use within GRACO equipment to provide secure, leak-resistant connections and allow for rotational movement between connected components.

Key Features:

• Union Swivel Fitting
• 3/4"
• Compatible with GRACO fluid handling systems, including Reactor 2 Ratio Monitor Kits (not used with Reactor 2 Integrated systems)
• Allows for rotational movement between connected hoses or pipes
• Designed for secure, leak-resistant connections
• Ease of maintenance and reliable performance in demanding environments

Applications:
Used in GRACO fluid handling and spray equipment, particularly in systems requiring flexible hose or pipe connections, such as in the Reactor 2 Ratio Monitor Kit for polyurethane and epoxy dispensing systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety in fluid handling systems.
• Ensure proper alignment of hoses or pipes before tightening the union
• Inspect fitting for damage or debris prior to installation
• Tighten securely to prevent leaks, but avoid over-tightening to prevent damage to threads or seals
• Regularly inspect for leaks or wear
• Replace if damaged or if leaks are detected
• Clean fittings during routine system maintenance
