The GRACO 127657 is a black union fitting designed to connect a 3/4" barb hose to a 1" BSP (British Standard Pipe) thread. Its material is not explicitly stated, but it is commonly used in fluid handling systems for reliable, leak-resistant connections. This fitting is intended for use in GRACO equipment, particularly in applications involving fluid transfer such as DEF (Diesel Exhaust Fluid) systems.

Key Features:

• Union fitting
• 3/4" Barb X 1" BSP
• Compatible with GRACO equipment, especially for DEF and fluid transfer applications
• Black finish for corrosion resistance
• Barbed end for secure hose attachment
• BSP threaded end for standard pipe connections
• Compact design for easy integration

Applications:
Used in fluid transfer systems, particularly for DEF (Diesel Exhaust Fluid) and other industrial fluid handling applications within GRACO equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Ensure both ends are clean and free of debris before installation
• Use appropriate tools to tighten the BSP threaded end to avoid cross-threading
• Push the hose firmly onto the barbed end for a secure fit
• Check for leaks after installation and during routine maintenance
