The GRACO 15T643 is a swivel tee fitting designed to connect fluid lines within GRACO equipment. It is engineered for heavy-duty performance and is typically used in industrial fluid handling systems. The material is not specified in available sources, but GRACO fittings are generally constructed from robust metals or alloys for durability. Its intended use is to provide a secure, leak-resistant connection between lines of different diameters (3/8 NPT and 1/2T) in fluid transfer applications.

Key Features:

• Swivel Tee Fitting
• 3/8 NPT X 1/2T
• Designed for use with GRACO fluid handling equipment
• Engineered for heavy-duty, lasting performance
• Swivel design for ease of installation and alignment
• Reliable, leak-resistant connection
• Quick shipping of genuine parts to minimize downtime

Applications:
Used in industrial fluid transfer systems, including lubrication, paint, and chemical handling applications. Suitable for environments requiring robust, reliable connections such as mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of equipment. Non-genuine parts may compromise system integrity and void warranties.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape as recommended by GRACO
• Hand-tighten before final torque to avoid cross-threading
• Regularly inspect fittings for leaks or wear as part of preventative maintenance
• Perform routine inspections for leaks, corrosion, or damage
• Replace fittings at the first sign of wear or failure
• Follow GRACO’s recommended maintenance schedule for your specific equipment
