Technical Specifications

Why This Adapter Is Important

The Graco 127324 plays a crucial role in maintaining consistent pressure and preventing leaks within your sprayer system. It’s especially useful when connecting NPT pump ports to JIC hydraulic hoses. The durable carbon-steel body withstands high operating pressure, making it reliable for contractors and professional painters.

Installation & Best Practices

• Use PTFE tape or approved thread sealant on the NPT threads only (never on JIC flare).
• Ensure both sealing surfaces are clean and undamaged before assembly.
• Tighten to proper torque to avoid leaks or thread damage.
• Check fittings periodically during heavy use, especially in high-pressure applications.

Safety Notes

Always depressurize your sprayer before replacing or tightening fittings. Improper installation or using non-matching threads may result in leaks, equipment failure, or injury.
