Even high-quality fittings can fail if not properly maintained or installed. Recognizing the root causes of failure is key to preventing future issues and maintaining consistent system performance.

Typical Failure Modes:

• Leaks at the Connection: Often due to improper installation, worn O-rings, or damaged threads.

• Tubing Blowouts: Caused by excessive pressure, weak tubing grip, or incompatible materials.

• Corrosion or Cracking: Happens when fittings are used outside of their rated environment or exposed to aggressive media.

Troubleshooting Tips:

• Inspect fittings and tubing for visible wear or damage

• Check that tubing is fully inserted and straight

• Replace degraded seals or O-rings immediately

• Use correct thread sealant and torque for threaded fittings

Preventive Measures:

• Use fittings rated for your specific pressure, temperature, and environmental conditions

• Avoid reusing old fittings

• Include leak testing as part of routine system maintenance

Summary:

Understanding common fitting failures helps you diagnose and address issues quickly, reducing downtime and ensuring safety. Regular maintenance and proper installation are your best defenses against failure.
