Points Worth Checking to Buy Metric Compression Fittings

In the instrumentation and other complicated industrial procedures, proper fittings are a major requirement to ensure leak-proof connections. They facilitate in making a torque-free seal between the tubes and pipes.

When you are looking to improve the overall efficiency of your industrial applications, it is important to choose the right type of fittings. They can maintain the safety during operations and ensure precision required in your applications. The metric compression fittings are a preferred option for such conditions. They aren’t threaded but can be used for making tight connections using their unique design. These fittings have a compression nut and a ferrule to make the connection. There are threads to hold the body of the fitting tightly. The nuts are properly tightened to press the ferrule tightly against the tubing in a connection. Though it does not require special tools for operating, there are some important factors to be considered for making the right selection. Here, they are:

The Torque:

If you want to make a torque-free seal during an instrumentation or process tubing application, you need to buy metric compression fittings with a silver-plated nut. This internal silver plating helps in preventing galling at the extremely high temperatures. This feature helps in reducing the torque when making the assembly.

The Fittings Materials:

The high-grade stainless-steel materials are used for making the high-quality compression fittings. They become resistant to corrosion and aggressive chemicals due to this procedure. The ideal choice in this context is the 316-stainless steel material that follows the industry specifications. This metal is heat-code traceable to the factory settings and this feature enhances the overall safety features of the fittings.

The Sizing:

Along with the perfect materials, you also need to choose the right sizing when looking to buy metric compression fittings. You should look for the appropriate sizing angles that are tapered slightly at the base of a tube socket. As a result, they do not stick to the body of the tube.

The Ferrules:

In the compression fittings, ferrules are used for making the connections. In this regard, you should prefer precision-machined front and back ferrules for a strong grip. With their case-hardened construction, they offer better resistance against vibrations. Here, you should check the edge of front ferrules minutely. It should be uniform to make tight connections between the fitting body and the tube.

The Interchangeability:

The interchangeability of the components is an important consideration when looking for high-quality metric compression fittings. Buy them from reputed manufacturers to avail this feature. In case if the performance and reliability of your fittings get affected, you can replace the components of an interchangeable product.

Pipe Threads:

Typically, these fittings have one male NPT pipe thread and one female NPT pipe thread. They are designed for maximum tolerances and offer better thread engagement for making strong connections.

Gaugeability:

In the engineered products like these fittings, it is important to maintain strict tolerances for better performances. Hence, make a selection accordingly. The fittings with gaugeability can be easily checked before the systems get pressurized for their installation.

Apart from these, you should also check the fittings for their operating parameters like temperature and pressure ratings. Check all these points comprehensively for making a wise selection.
