SG-LOK Tube Fittings Malaysia – What is a Double Ferrule Tube Fitting?
SG-LOK tube fittings Malaysia are widely used in instrumentation, hydraulic, chemical processing, oil & gas, semiconductor and pharmaceutical industries. Double ferrule tube fittings provide a leak-tight connection without welding and are trusted in critical applications worldwide.
What is a Double Ferrule Tube Fitting?
A double ferrule tube fitting is a mechanical fitting designed to connect tubing securely while preventing leakage under pressure.
The fitting consists of four components:
- Fitting Body
- Front Ferrule
- Back Ferrule
- Nut
When the nut is tightened, the front ferrule forms a leak-tight seal while the back ferrule grips the tubing firmly. This design provides excellent sealing performance and vibration resistance.
Advantages of Double Ferrule Tube Fittings
Leak-Free Performance
The dual ferrule design creates a reliable seal suitable for high-pressure applications.
Excellent Vibration Resistance
Double ferrule fittings are commonly used on pumps, compressors and process equipment where vibration is present.
Easy Installation
No welding or special equipment is required. Installation can be completed using standard hand tools.
Reusable Design
Fittings can be disconnected and reassembled when maintenance is required.
High Pressure Capability
Suitable for instrumentation systems, gas lines and hydraulic applications.
Common Applications
SG-LOK tube fittings Malaysia are commonly used in:
- Oil & Gas Industry
- Chemical Plants
- Water Treatment Systems
- Semiconductor Industry
- Pharmaceutical Industry

Why Do Tube Fittings Leak?
The most common causes are:
Under-Tightening
Insufficient tightening prevents the ferrules from gripping the tubing correctly.
Over-Tightening
Excessive tightening may damage the ferrules and tubing.
Wrong Tubing Size
Using incorrect tubing dimensions can cause sealing problems.
Damaged Tubing Surface
Scratches and dents can lead to leakage.
Improper Installation
The tubing must be fully inserted before tightening.
