Domestic and Drinking Water

In potable water systems, no compromises are allowed: maximum hygiene must be guaranteed and the risk of bacterial contamination or the release of harmful substances must be stopped. AISI 316L stainless steel is the material that best meets these requirements as per research. Plastic because of its chemical composition, and iron because of its sensitivity to rust & corrosion may release pollutants. Copper, even though it is much noble, can be subject to oxidation. Due to this, for new construction or renovations, the absolute choice for domestic water systems is to use Rhinox stainless steel pipes and fittings.


The Rhinox Press fitting line in AISI 316L Stainless Steel – GAS (M profile) is expressly dedicated to this application and is certified according to current standards. Many installers associate systems to pressed copper but pressed stainless steel is also perfect for the purpose and offers a lot of advantages.The fittings are identified by an anti-tampering label and equipped with an O-ring, specifically designed for combustible gases and particularly resistant to wear. Unlike other solutions that offer a limited range of diameters, the catalogue of Rhinox extends to big size diameters.


Rhinox Stainless Steel Press Fittings carbon steel pipes and fittings are generally used in closed circuit heating system with cast iron, steel, or aluminium radiators. Ultra-modern radiant heating systems require the use of flexible pipes in the ending sections but for first level distribution, rigid metal solutions are often needed to be used in projects with high budgets, stainless steel can be used while carbon steel makes an affordable choice.

Hydronic Air Conditioning

Another Application of the Rhinox Press fitting system especially in the industrial, commercial, hospitality, and hospital sectors is hot/cold climate control with fan coil terminal & Plumbing circuits and s. One of the many advantages of this air conditioning system is that it can be combined with renewable energy sources. Although Stainless steel and Carbon steel both are suitable for circulating hot water, the Carbon steel is not very appropriate for conveying chilled water as the formation of condensation on the external surface could trigger localised corrosion where perfect insulation cannot be achieved. Due to these very reasons, stainless steel with the proper insulation is much more suitable and longer-lasting.

Fire Extinguishing Systems

There are several types of fire extinguishing systems each one based on the type of extinguishing agent used: foam, air, or water with the sprinklers. Though all of these systems are built using old methods of galvanised steel with welded or threaded joints or with groove fittings, the Rhinox Stainless Steel Press Fittings is the best alternative in both carbon steel and 316L stainless steel.

Solar Thermal Energy

Construction and system engineering’s future is also driven by environmental responsibility. The amount of heating obtained from solar energy is a growing industry as it allows emissions and atmospheric pollution to be lowered to an extent. Using Stainless steel is the best choice because it is durable & fully recyclable material.


The system exclusively dedicated to heating, in that system cooling is implemented independently with gas or water solutions as per needs. For industries, coolers supplied with chilled water are the best choice in terms of efficiency and energy savings. For this particular application, the use of Stainless steel pipes and fittings is the best choice due to its durability resistance to corrosion.

Compressed Air

For the distribution of compressed air, mainly in the industrial sector, Stainless Steel Press Fittings proves to be of the best. Stainless steel press fittings support temperatures between -20°C and +120°C and a good pressure. Though Carbon steel is more affordable a slightly more costly alternative but with superior characteristics is using stainless steel pipes & fittings.


The other important industrial application involves systems for the conveying of oily substances such as lubricant fluids and fuels. For this purpose, both the stainless steel and carbon steel systems can be used but the Carbon steel is used only when there is the surety of total absence of air and perfect insulation. In both of these cases, the fittings will be equipped with the O-ring.
