The GRACO 116766 is a straight adapter designed to connect components with 3/8-inch NPT (National Pipe Thread) female threads to those with 1-1/16-12 JIC (Joint Industry Council) male threads. Its material is not specified in available documentation, but such adapters are typically made from steel or brass for durability and chemical resistance. This adapter is intended for use within GRACO fluid handling and dispensing equipment to ensure secure and leak-free connections between different thread standards.

Key Features:

• Straight Adapter
• 3/8 NPT x 1-1/16-12 JIC
• Compatible with GRACO equipment requiring 3/8 NPT to 1-1/16-12 JIC thread conversion
• Provides secure connection between different thread standards
• Designed for reliability and leak prevention
• Ease of installation and maintenance

Applications:
Used in GRACO fluid handling, lubrication, and dispensing systems where conversion between 3/8 NPT and 1-1/16-12 JIC threads is required. Suitable for industrial, mining, and agricultural applications.

Installation Notes:

• Using genuine GRACO adapters ensures proper fit, leak prevention, and equipment reliability.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant or tape as needed
• Hand-tighten before using a wrench to avoid cross-threading
• Check for leaks after installation and during operation
• Regularly inspect for wear, corrosion, or damage
• Replace if signs of leakage or thread damage are present
