| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible fittings with 316 stainless steel. | Always use fittings specifically designed and rated for 316 stainless steel to prevent galvanic corrosion and ensure long-term integrity. |
| Over-tightening threaded connections, leading to stress cracking. | Follow recommended torque specifications for threaded connections to avoid damaging the pipe or fittings and ensure a reliable seal. |
