The GRACO 558794 is a hexagonal bushing designed to connect and adapt between 3/4 inch and 1/4 inch NPTF pipe threads. Its material is not explicitly stated in available sources, but it is a standard industrial fitting typically made from steel or brass. This part ensures a secure, leak-resistant connection within GRACO fluid handling equipment, facilitating proper flow and system integrity.

Key Features:

• Bushing
• 3/4 X 1/4 NPTF
• Compatible with GRACO equipment requiring 3/4 to 1/4 inch NPTF thread adapters
• Hexagonal shape for easy installation and removal with standard tools
• Designed for seamless fit and reliable performance in GRACO systems

Applications:
Used in fluid handling and lubrication systems where a reduction from 3/4 inch to 1/4 inch NPTF pipe thread is required. Commonly found in industrial, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, leak prevention, and system reliability.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant or tape as recommended for NPTF fittings
• Tighten securely using a wrench on the hexagonal body to avoid damage to the fitting or equipment
• Regularly inspect for leaks or wear
• Replace with genuine GRACO parts to maintain system integrity
