Graco 15G713 Nut Air Plug

Nut – Model 15G713 (Air Plug)

The 15G713 NUT, AIR PLUG is a high-precision sealing nut designed for air-line or air-inlet ports in spray equipment assemblies. This component ensures a reliable, leak-free connection of plug or cap components within the air supply passage of professional spray systems.

Applications & Fitment

Designed to be installed on air-assisted spray guns or pneumatic control modules, this air plug nut secures the sealing plug that closes or defines the air passage. It is especially suited to systems where a clean, robust air-supply connection is critical for consistent performance and safety.

Key Specifications

Product Highlights

• Provides secure and accurate sealing of air-plug connections to maintain system integrity.
• Ensures consistent air supply performance by preventing leaks at the plug interface.
• Manufactured to strict tolerances to fit properly and avoid over-torque or mis-fit.
• Essential maintenance item for spray equipment relying on pneumatic control or air-assisted operation.

Installation & Usage Notes

Prior to installation of the 15G713 nut, ensure the air supply is disconnected and the system is depressurized. Remove the existing plug nut or cap, clean the threads and sealing surface, then thread the new nut on until properly seated. Tighten to the manufacturer’s recommended torque to avoid air leakage. After installation, reconnect the air supply and check for any air-leak sound or pressure drop to confirm integrity.

Maintenance & Care

• Inspect the nut and its surrounding area periodically for signs of wear, thread damage or air leakage.
• Ensure the plug and nut interface remain clean and free of debris that could compromise sealing.
• If leakages are observed or thread engagement is poor, replace the nut to maintain reliable air system function.
