Some Common Questions for Compression Fittings?

1.What is the most common cause of leaking compression fittings?

It is critical to avoid over-tightening the nut or else the integrity of the compression fitting will be compromised by the excessive force. If the nut is overtightened the ferrule will deform improperly, causing the joint to fail. Indeed, overtightening is the most common cause of leaks in compression fittings.

2.Should you use PTFE tape on compression fittings?

No. PTFE tape is not designed to seal compression fittings and is ineffective at doing so.

3.How reliable are compression fittings?

Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems. In general, compression fittings are not as resistant to vibration as soldered or welded fittings. Repeated bending may cause the ferrule to lose its grip on the tube.

4.Can you reuse compression fittings?

They are safe to be reused and apply to half the movement of the pipe outward from the fitting. In hydraulic process, compression fittings basically assure some secure fit in pipe connections. Leaks are only possible if they are not properly installed to each end of the fluid line.
