A compression fitting joins metal tubing to a port or to another tube without welding. On instrumentation lines the usual stainless pattern is a double-ferrule (front + back ferrule) nut that bites annealed tube when you tighten to the body.
Why export buyers use them
- No hot work on the panel
- Remakeable joints for maintenance
- Metric and imperial tube OD in one catalog family
FerruleX manufactures stainless steel compression fittings in SS304 / SS316 / SS316L with NPT, G and metric thread ends.
Compression vs threaded vs weld
| Need | Typical choice |
|---|---|
| Removable instrument tube | Compression (double ferrule) |
| Pipe thread ports only | Threaded adapters / valves |
| Permanent process joint | Weld ends |
Factory RFQ tip
Send tube OD, thread on the port end, material and quantity. Soft annealed tube seals more reliably on gas service — ask if you are unsure about hardness. Browse the compression category or request a quote.
