Pressfittings for compressed air: how to maintain system efficiency over time

Steel pressfitting systems are perfect for industrial compressed air systems. Let's take a look at some of the winning features of pressfittings combined with some tips to make the system efficient and long-lasting.
Using steel pressfittings to build industrial compressed air systems is a quality choice that is paid back over time.
Many manufacturing activities are heavy users of compressed air for direct processes and for supplying certain types of machinery.

Machinery failures and product imperfections are unexpected problems that can cost time and money. For this reason, a compressed air system must be durable and built out of the best materials.


Steel, especially AISI 304 and AISI 316L stainless steel, is able to resist the impact of any impurities transported with the compressed air.
Some piping systems made with plastic material may become scored inside when they come in contact with impurities that pass through and impact at high speeds. Detachment of this material can further clog the circuit.


If you want a safe compressed air system that is efficient and long-lasting, choose a steel pressfitting system. You can also choose carbon steel pressfittings. But if you want the best value in cost and longevity of the system, you can choose 316L stainless steel fittings combined with 304 stainless steel pressfitting pipes, as explained in this article.

Compressed air with or without oil?

Some industrial compressed air systems allow the presence of oil in the system and some don't.
If there is more than ≥ 5 mg/m3 of oil, we recommend replacing the standard o-ring (EPDM Black) with FPM /red o-rings.

Wet the o-ring with water before inserting the pipe in the fitting



What contaminants are in compressed air?

  • Oil from the environment or placed in circulation by the compressor mechanisms.
  • Humidity present in the environment: the pressure changes inside the circuit promote the formation of condensation inside the utilities.
  • Dust of organic and non-organic origin. Compressing the air also compresses the contaminants in it, increasing the concentration up to 900%.

What are the consequences of a compressed air system with contaminants?

First of all, premature wear of the system and the machinery connected to it.
Second, it can also impact the facility's production with finished products damaged by the presence of oil or even irrevocably damaged because it was hit by projected particles.
Finally, the presence of water inside the circuit can clog the utilities, blocking system functionality.

How can we keep a compressed air system efficient while safeguarding the quality of the air delivered?

By positioning certain machinery that ensure the quality of the air delivered and, consequently, the longevity of the system:
  • Conduit system made with steel pressfittings: maximum performance over time due to the superior quality of the material;
  • Ensuring the absence of oil: every industrial process can more or less tolerate the presence of oil. Through three or more stage filtering processes, the presence of oil can be made infinitesimal. If you need a system that is completely free of oil, the only method is to use a compressor without oil as a supply source.
  • Keeping the relative humidity of the system constant, the performance remains efficient over time. The use of dryers, prevents the possible formation of rust (in systems built with carbon steel, dryers are mandatory). They also avert possible problems in the utilities and in general in the overall productivity of the system.
  • Elimination of dusts and contaminants: cascaded filters must be used with a filtering power that goes from largest to smallest.

In an increasingly competitive industrial market, it is good to be able to count on a reliable industrial compressed air system.


Saving by choosing apparently less costly materials and "less complex" filtering systems are potentially penalizing choices, especially when related to an investment that must lead to profit.

Efficiency and production with the fewest possible defects are sources of income. Line downtime and claims are not.
