The GRACO 122731 is a hydraulic adapter designed to connect 1/4 inch NPT (National Pipe Thread) female to SAE 04 (O-ring Boss) male threads. It is typically constructed from durable materials such as carbon steel and is intended for use in hydraulic systems to ensure secure, leak-free connections between components within GRACO equipment.

Key Features:

• Hydraulic Adapter
• 1/4 NPT Female x SAE 04 Male
• Carbon Steel (typical for similar GRACO adapters)
• Compatible with GRACO hydraulic systems and equipment requiring 1/4 NPT to SAE 04 connections
• Straight thread design for secure fit
• O-ring boss (ORB) for leak-free sealing
• Durable construction for demanding hydraulic environments
• Ease of installation and maintenance

Applications:
Used in hydraulic systems for connecting hoses, pipes, or components with differing thread standards. Suitable for industrial, agricultural, and mining equipment where reliable hydraulic connections are required.

Installation Notes:

• Using genuine GRACO adapters ensures compatibility, reliability, and safety in hydraulic systems, reducing the risk of leaks and equipment failure.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant or use O-ring as specified for the connection type
• Hand-tighten before using a wrench to avoid cross-threading
• Check for leaks after installation and during system operation
• Regularly inspect for signs of wear, corrosion, or leaks
• Replace O-rings or adapters if damage is detected
• Follow GRACO maintenance guidelines for hydraulic systems
