Four Key Factors to Consider when selecting Instrumentation Tube Fittings

Four Key Factors to Consider when selecting Instrumentation Tube Fittings

One of the first phases in manufacturing a leak-free instrumentation system is choosing the applicable tube for the chore. No system stability is complete without this necessary part and its suitability with the other components. In this post, you will go over four key considerations to keep in mind when selecting a conventional instrument tube to be used with tube fittings.


Techtube Instrumentation Fittings have been designed for a wide range of applications that need the highest level of product consistency. Their suitability with the specified tubing is critical for ensuring a high level of reliability over time.


Four Key Factors

  1. Material of Tube Fitting

Consider the operating conditions, such as temperature, pressure, and media, while choosing the proper material for tube fittings. The approximate life of such tubing, as well as its expense and environmental suitability, must all be evaluated.


Corrosion-resistant materials should be used in most sectors. Stainless steel, copper, carbon steel, and tubing are the most popular materials utilized. Because the tubing is corrosion-resistant, this is one of the preferred materials.

  1. The texture of Tube Fitting

The tubing should be lighter than the materials used in the fittings. For leak-free couplings, however, a specific tubing hardness must be reached.


When it belongs to stainless steel tubing, there is a range of hardness criteria that perform well in various situations. All of our tubings have been thoroughly tested for great performance and to provide the best importance in terms of construction costs.


To achieve perfect joints, installers should complete a 1-1/4 turn. This is particularly the case with tougher tubing with more torque. For instance, stainless steel tubing ought to have a hardness value of Rb 80 or less.

  1. Wall thickness of Tube Fitting

The tube fitting is convenient in a combination of wall thicknesses. Their strength grades demonstrate their suitability for specific usage.


Thickness typically ranges from 0.028 to 0.109 inches. Tube Fitting up to 1-inch diameter should have these wall densities. The wall thickness of larger tubes, which can vary from 0.125 to 0.167 inches, may be gained.

  1. Surface coating for tubing

Depending on the application requirements, a variety of surface coatings are offered.


Metal tubings, for instance, are often covered with corrosion-resistant coverings, particularly in climates where such consequences are familiar. Still, the ideal alternative is to use Techtube UNS S32205 Instrumentation Fittings.



Any instrumentation fitting's design, selection, and installation are critical to the conserving energy, performance, and management of any fluid and gas process of production. The device is safer, more robust, and has a longer service life when leakage is reduced, friction is reduced, and corrosion resistance is ensured. Automated processes must be optimized for maximum efficiency, which can only be accomplished through proper safety and installation considerations.


When design requirements are met, fewer cycles are required to meet manufacturing deadlines, resulting in increased productivity and lower operating costs.
