A Guide to Assembling Twin Ferrule Compression Fittings

Twin Ferrule Compression Fittings are generally great for leak-free connections, which is often the case with process instrumentation and industrial applications.  

Aimed to meet the requirements of the oil & gas, petrochemical, power-based industries, twin ferrule compressions are one of the most demanded options in fittings.

In addition to guaranteeing best possible performance and value for high-pressure or vacuum fitting needs, they work equally well for increased or decreased temperatures, vibrations and quick loading, and acerbic or dangerous surroundings. 

Stated below is a quick guide to assembling twin ferrule compression fittings; keep on reading:

A Few Pre-Assembly Instructions

Step#1 – Cling to a pre-assembly tool in a vice. A vice is basically an automatic instrument that’s used to protect an object to facilitate work to be undertaken. Then, bring the joint together by following the instructions laid down in the product’s manual. 

Step#2 – Detach the tube from the pre-assembly tool. 

Step#3 - Place the tube assembly into the body and then track the instructions for re-assembling found in the same manual.

Pre-Assembly Guidelines and Considerations

Generally, pre-assembly tools are made using toughened Maraging Steel. Maraging steel is basically a steel alloy that comprises 25% nickel and other metals. Moreover, they are intended to hold out recurring assemblies. In addition, pre-assembly tools are also utilized to ascertain that the joints are accurate.

For best results, it is important to guarantee that assembling tools are clean, sanitized and well lubricated. 

If you’re thinking why pre-assembling procedures are important, here are some reasons: the assembling process can bring forth a host of complications and obscurities, particularly if the compression fittings are to be utilized in limited spaces. Generally, broad wall tubes and adaptors of vertical pipes (extending from water supply) can also sprout multiple problems. Pre-assembly guarantees that the fittings are placed and installed in the most precise manner. 

Lastly, pre-assembling lessens installation problems when the size of tube goes beyond 1/2" (12mm) OD. 

Assembling the Twin Ferrule Compression Fittings

Step#1

Slash the tube as per the needed length. However, make sure you leave the ends straight to the axis of the tube, getting rid of all rough projections.

Step#2

Now, fit in the prepared tube within the fitting assembly, making sure that the end of the tube completely makes way into the fitting and covers the supporting diameter. Ensure the nut is tightly fixed.

Step#3

For sizes such as 1/16", 1/8", 3/16", stiffen the nut 75% of a turn to conclude the assembling process.

As far as the other sizes are concerned, 1.25 turns from finger-tight will work fine.
