The GRACO 168688 is a bushing designed to connect components with different thread types—specifically, 1/2-14NPT (National Pipe Thread) and 1/2-27 UNS-2B (Unified National Special thread). Its material is not specified in available sources, but it is intended for use in GRACO spray foam and spray application equipment to ensure secure and leak-free connections between parts with mismatched threads.

Key Features:

• Bushing
• 1/2-14NPT X 1/2-27 UNS-2B
• Compatible with GRACO spray foam and spray application equipment
• Enables secure connection between components with different thread types; supports reliable and leak-free operation in spray systems

Applications:
Used in spray foam and spray application systems to connect components with mismatched thread types, ensuring proper fluid transfer and system integrity.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of spray equipment.
• Ensure threads are clean and undamaged before installation; use appropriate thread sealant if required; hand-tighten before final torque to avoid cross-threading; consult equipment manual for specific installation instructions.
• Regularly inspect for leaks or wear; replace if damaged or worn; use only compatible parts for maintenance and repairs.
