The GRACO 102310 is a hex nut with a nylon cap, designed for secure fastening and protection in GRACO equipment. It is made from nylon, providing corrosion resistance and vibration dampening, and is used to fasten components in high-pressure fluid handling systems.

Key Features:

• Hex nut with nylon cap
• No. 10–32 thread
• Nylon cap over metal hex nut
• Compatible with GRACO ball valves, check valves, and swivels (e.g., Model 237469, Series A)
• Corrosion-resistant nylon cap
• Vibration dampening
• Protects threads from contamination
• Easy to install and remove

Applications:
Used in GRACO fluid handling equipment such as ball valves, check valves, and swivels, particularly in high-pressure lubrication and maintenance systems.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure applications.
• Ensure threads are clean and free from debris before installation
• Hand-tighten the nut, then use a wrench for final tightening as required
• Inspect for wear or damage during routine maintenance
• Replace if nylon cap is cracked or damaged
