Installation Best Practices
To install the 15A044 fitting properly, always prepare the port and use the correct installation methods to achieve a reliable seal and prevent leaks.
- Clean the pump inlet port to remove debris before threading.
- Apply NPT-compatible thread sealant to ensure a tight, leak-proof joint.
- Tighten to Graco’s recommended torque specification to prevent damage.
- After assembly, run the pump cautiously at low pressure to check for leaks.
- Inspect periodically during maintenance to ensure the fitting remains secure.
Signs It’s Time to Replace the Fitting
