Reducing nipple connector, copper, for medical gases 16-12 MG5243 0161200

Application in Medical and Vacuum Installations

This reducing connector, made of high-purity copper, is a key component in medical gas distribution systems. Its primary function is to safely connect pipes of different diameters – in this case, transitioning from 16 mm to 12 mm – while maintaining the tightness required for media such as oxygen, nitrogen, medical air, or carbon dioxide. Thanks to the use of Cu-DHP material (phosphorus-deoxidized copper) with 99.99% purity, the fitting minimizes the risk of chemical reactions with the transported gases, which is fundamental for the safety of patients and personnel.

The product has been specially prepared for installations requiring the highest hygienic and technical standards. All components are factory-cleaned and degreased, then individually packaged, eliminating the risk of internal pipe contamination prior to installation. This solution facilitates the work of installers, who do not need to worry about additional end preparation before soldering.

Construction and Installation Principles

The fitting has the form of a simple reducing nipple, ensuring a smooth transition between two diameters without unnecessary collisions or flow disturbances. Both sides of the connector are equipped with push-fit sockets (for soldering), allowing flexible selection of the joining method:

• Soft soldering: Acceptable for some applications but requires precision.
• Hard soldering: Recommended for medical gas installations; requires the use of solders containing at least 2% silver.

The material (Cu-DHP copper) and compliance with PN-EN 1254 standards ensure joint durability even under varying pressure or temperature conditions. It is worth noting that the hydrocarbon content in the material is limited to below 100 mg/m², preventing the formation of deposits inside the pipeline.

Key Features and Compliance with Standards

By choosing this reducing connector, you receive a product meeting rigorous industry requirements. It guarantees corrosion resistance and chemical inertness thanks to the use of Cu-DHP (CW 024A) copper with 99.99% purity. The element is ideally suited for vacuum systems and gas pipelines transporting oxygen, helium, nitrogen, or CO2. Compliance with PN-EN 1254 and PN-EN 13348 standards for fittings used in gas installations confirms its suitability for professional applications. Additionally, thanks to factory cleaning and degreasing, the connector is ready for capillary soldering without requiring any additional processing by the installer.

Thanks to precise manufacturing and appropriate material selection, this connector guarantees leak-tight joints throughout the entire service life of the installation. It is a proven solution for both new hospital projects and the modernization of existing technical media distribution systems. It is worth noting that the reduction from 16 mm to 12 mm is achieved via soldering sockets on both sides of the component.
