1. Check Material Labels to Avoid Inferior Products
When purchasing, check the product testing report or material certificate, or perform a magnet test (304 stainless steel has extremely weak magnetism).
2. Pay Attention to Manufacturing Process to Ensure Sealing
High-quality fittings are precision cast or CNC machined, with no cracks or sand holes on the surface and clear threads. The sealing structure (such as O-rings or compression fittings) must match the pipeline to avoid leakage.
3. Choose the Appropriate Specifications to Avoid Installation Problems
Select the corresponding model based on the pipeline diameter, pressure rating, and connection method (such as flared or welded). Consult the supplier for technical solutions if necessary.
