Stainless steel compression tube fittings are chosen in many different industry settings, due to their durability and quality service.

There are many other materials available for compression tube fittings. However, stainless steel is one of the least expensive yet durable materials used in any sector. It withstands corrosion from various chemicals, is impervious to temperature fluctuations, and maintains proper seals under pressure.


Stainless steel fittings are so durable that they are often used over and over again, through several sets of hoses. If a fitting is damaged in some way, it should, of course, be discarded. However, stainless steel is used for such a wide variety of processes because it will ensure there is no leakage, regardless of pressure or temperature.

In addition, when properly cleaned stainless steel fittings can be used for different hydraulic materials without fear of failure. As long as the fitting is functioning properly, it can be reused for any approved mechanical, chemical, or industrial use.


Corrosion can be a serious issue in some applications. Various chemicals are often present and can corrode joints and the interior of non-approved fittings. Stainless steel fittings are more resistant to corrosion due to passivation; a vital process enhancing their corrosion resistance. This involves treating the steel with an acid solution, creating a thin protective oxide layer ensuring durability that often outlasts even the hydraulic hoses.


Hydraulic hoses are manufactured within certain parameters relating to the type of fluids or gasses they will be transported. They are also manufactured to withstand pressure from pumps, compressors, and other machinery that propel the fluid or gas.

Stainless steel fittings are ideal for handling the ranges of pressure delivered by tools and machinery. Whether the pressure is steady or fluctuating, the fitting will probably last longer than the hose under various pressure conditions.

Burst pressure may be a problem for some brands of hoses, but stainless steel fittings should be just fine under burst conditions and vacuums as well.

Vibration while under pressure may cause the failure of some materials, but the stainless steel fitting will remain dependable when installed properly.


You can order most stainless steel compression tube fittings according to the desired gauge. You will need to refer to guides to make sure you select an approved gauge for the tube and processes you use. Most of the fittings are high-quality enough that the threads will work properly without galling. The fittings usually install easily and provide a good seal.
