In hydraulic system failures, fitting leaks are among the most common and frustrating issues. They cause fluid loss, environmental contamination, pressure instability, and downtime. While  Bite-Type Tube Fittings are popular for their compact design, achieving a consistent leak-free seal is critical. At  RUIHUA HARDWARE, a trusted manufacturer, we understand that "zero leaks" isn't accidental—it's a result of adhering to strict precision rules. Here are the four key principles we follow to ensure reliability.

Rule 1: Precise Selection & Preparation – The Foundation of Zero Leaks
A correct start is essential. Always ensure the tube OD matches the fitting specification exactly. Use a tube cutter for a square cut and deburr thoroughly. As a manufacturer,  RUIHUA HARDWARE emphasizes that foundation accuracy determines system reliability.
Rule 2: Proper Installation – Master the '1¼ Turns' Method
The sealing action requires the ferrule to both bite into the tube and provide elastic compensation. The standardized process is: assemble, mark, pre-assemble by tightening the nut 1¼ turns (450 degrees), and finalize. Overtightening is a major cause of failure—a key point in  RUIHUA HARDWARE's installation guidelines.
Rule 3: The Heart of the Matter – Non-Negotiable Ferrule Quality
The ferrule is the core of the fitting. It must have sharp edges, proper geometry, and be made from quality steel with correct heat treatment for a hard yet elastic performance.  RUIHUA HARDWARE, as a professional manufacturer, ensures every ferrule meets exacting standards in form, material, hardness, and finish. Never mix ferrules from different brands—always use genuine parts.
Rule 4: Maintenance & The "One-Time-Use" Ferrule Principle
Regular inspection and pressure testing are vital. Most importantly, a ferrule is a single-use component. After any disassembly, it must be replaced. This is a fundamental practice  RUIHUA HARDWARE advocates for long-term system integrity.
