In many piping and instrumentation setups, connections need to be tight and reliable without depending on welding. This is where SS Double Ferrule Union is commonly used.
It is a simple fitting, but in actual use, it plays a critical role in preventing leakage and maintaining a stable connection between tubes.

Construction of SS Double Ferrule Union
A SS Double Ferrule Union consists of a few key parts that work together:
- Body – The main fitting that connects both ends
- Front Ferrule – Provides sealing by gripping the tube tightly
- Back Ferrule – Supports the front ferrule and improves holding strength
- Nut – Tightens the entire assembly and ensures proper compression
The double ferrule design is what makes the difference. Instead of relying on a single grip, the two ferrules work together to create a stronger and more reliable seal.
