The GRACO 15B729 COUPLING is a high-pressure coupling adapter designed to connect 3/8-inch NPT (female) to 3/8-inch NPSM (male) fittings. It is typically constructed from robust materials suitable for high-pressure fluid handling and is intended for use within GRACO spray equipment to ensure secure, leak-free connections at extreme pressures.

Key Features:

• Coupling Adapter
• 15B729 / 3/8 NPT (F) x 3/8 NPSM (M)
• 7250 PSI (500 bar, 50 MPa)
• Compatible with GRACO spray equipment requiring 3/8 NPT (F) to 3/8 NPSM (M) connections at high pressure
• High-pressure rating for demanding industrial applications
• Compact design for easy integration into existing systems
• Reliable, leak-free connection for critical fluid transfer

Applications:
Used in high-pressure spray systems, plural-component sprayers, and other GRACO equipment requiring secure, high-pressure fluid connections.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains equipment warranty and safety standards.
• Ensure threads are clean and undamaged before installation
• Apply appropriate thread sealant if required by the application
• Tighten securely to prevent leaks at high pressure
• Regularly inspect for wear or damage and replace as needed
