45° elbow with SC 42 stainless steel - stainless / polished, model 2326 Sanpress 435363

Application and System Characteristics

This Sanpress Inox series fitting, made of stainless steel (grade 1.4401), is designed to create durable connections in piping systems with a diameter of 42 mm. Its primary function is to change the flow direction of the medium by 45 degrees, enabling flexible pipe routing in hard-to-reach areas or when bypassing architectural obstacles. Thanks to the use of noble steel alloyed with molybdenum, the fitting exhibits high corrosion resistance, making it an ideal choice not only for water supply installations (including potable water) but also for industrial systems such as compressed air, fire protection, and refrigeration technology.

The sealing material is made of EPDM rubber, ensuring tightness across a wide range of temperatures and pressures. The maximum operating pressure is 16 bar at 20°C, meeting the requirements of most standard building and industrial installations. It is worth noting that the seals are an integral part of the design – they require no additional assembly or lubrication before pressing, which speeds up the installer's work and eliminates the risk of human error during connection preparation.

Installation Safety and SC-Contur Technology

A key feature of this fitting is the use of SC-Contur (Safety Connection) technology. This is a specially shaped groove on the surface of the pressing sleeve that serves as a visual indicator of correct installation. If the installer forgets to press the connection or does so incorrectly (e.g., using the wrong die), the characteristic green dot visible on the sleeve's screen will remain exposed or will not be fully crushed. Consequently, during system tightness tests (even at low pressures from 0.1 MPa), a controlled leak will occur at the point of error, immediately signaling the problem. This solution significantly enhances the safety of the entire installation and eliminates the risk of failure after walls or floors have been closed.

The pipe joining process is fast and repeatable:

• No welding or brazing is required – avoiding the risk of pipe damage from high temperatures.
• No additional seals or adhesives are needed – sealing is provided by the factory-installed EPDM ring.
• Installation is performed using dedicated hydraulic or manual crimping tools that comply with manufacturer standards.
• The connection is durable and withstands thermal expansion cycles without loss of tightness.

Applications Across Industries and Operating Conditions

Due to its material (stainless steel 316) and the chemical resistance of the EPDM seals, this fitting can be used in environments with increased corrosion requirements. This is particularly important for marine installations (shipbuilding), agricultural applications (e.g., irrigation), or industrial settings where pipes may be exposed to atmospheric moisture or aggressive media. The external pipe dimensions it accommodates are 42 mm, and the length of each sleeve arm is 57 mm, facilitating spatial planning in tight pipe layouts.

The fitting features a one-piece construction, meaning there are no additional moving parts or threaded components that could loosen during operation. The availability of VdS certification for certain diameters confirms compliance with rigorous fire safety and technical standards in Germany and Central Europe, which is crucial when designing fire protection systems or public facilities with enhanced safety requirements. Thanks to this solution, installers have confidence in the quality of the connection even before commissioning the water supply or heating system. All operational parameters – such as an operating pressure up to 16 bar and operating temperature – have been selected to ensure reliability under typical installation conditions without the need for additional mechanical safeguards.
