The GRACO 167057 Stud, Swivel Union is a high-pressure swivel fitting designed to connect hoses or equipment with 3/8-inch and 1/2-inch threads. It is typically constructed from robust materials such as steel or brass for durability and is intended for use in lubrication, hydraulic, or fluid transfer systems within GRACO equipment. Its swivel design allows for flexible, leak-free connections under high pressure.

Key Features:

• Swivel Union
• 3/8 x 1/2
• Steel or similar robust material (not explicitly specified for this part number, but typical for GRACO swivel unions)
• Compatible with GRACO lubrication and fluid transfer equipment requiring 3/8-inch and 1/2-inch threaded connections
• Swivel design for flexible, leak-free connections
• Robust construction for high-pressure applications
• Reliable performance in demanding environments

Applications:
Used in lubrication systems, hydraulic systems, and fluid transfer applications where flexible, high-pressure connections are required. Suitable for industrial, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO replacement parts ensures compatibility, reliability, and safety in high-pressure applications. Non-genuine parts may compromise system integrity and performance.
• Ensure threads are clean and undamaged before installation
• Use appropriate thread sealant or tape as recommended by GRACO
• Tighten securely but avoid over-torquing to prevent damage
• Check for leaks after installation and during routine maintenance
• Inspect swivel unions regularly for wear, leaks, or damage
• Replace worn or damaged parts immediately to prevent system failure
• Follow GRACO’s recommended maintenance schedule for lubrication equipment
