Reducer coupling, nipple type, copper, for medical gases 22-12 MG5243 0221200

Intended Use and Application in Medical Installations

This reducing connector, made of 99.99% pure copper (Cu-DHP), has been specifically designed for the safe joining of pipes in medical gas distribution systems. Its primary function is to provide a smooth transition between a pipe with an outer diameter of 22 mm and a pipe with a diameter of 12 mm, enabling flexible installation design in hospitals, clinics, and laboratories. Thanks to the use of a material with high chemical resistance, this component is suitable for circuits transporting oxygen, nitrogen, carbon dioxide, helium, or medical air.

It is important to note that fittings from the Medical Gas series are manufactured in accordance with rigorous hygiene requirements. Each unit undergoes a cleaning and degreasing process prior to packaging, eliminating the risk of contamination of the gaseous medium. This is crucial for maintaining sterility in installations where even minor contaminants can disrupt the operation of medical devices or affect the quality of the supplied gas.

Construction and Installation Principles

This component is a simple reducing nipple that joins two copper pipes using capillary brazing technology. Both connection sides (22 mm and 12 mm) feature socket ends prepared for soft or hard soldering. For installers, this means the possibility of using solders containing silver (min. 2%), which guarantees leak-tightness and mechanical strength of the joint even under large pressure or temperature fluctuations.

The material used – phosphorus-deoxidized copper Cu-DHP – ensures excellent thermal conductivity and corrosion resistance, which is essential when working with aggressive chemical agents or in vacuum systems. The fitting complies with the requirements of standard PN-EN 1254 and can be used with pipes conforming to standard PN-EN 1057. Thanks to precise manufacturing and dimension markings on the product, installation is quick and free from errors in diameter selection.

Key Features and Operational Benefits

When selecting this reducing connector for medical gas installations, it is worth paying attention to its technical specifications, which translate into operational safety. The product is characterized by high-purity material, as manufacturing from Cu-DHP copper (99.99%) minimizes the risk of chemical reactions with the transported gas. Equally important is surface cleanliness – the product is factory-cleaned and degreased, then individually packaged, making it ready for installation without additional preparatory procedures.

For installers, brazing versatility is key, as it allows joining with both soft and hard solders (with silver addition), providing flexibility depending on the specific installation requirements. Dimensional precision also plays a significant role: the dedicated transition between 22 mm and 12 mm diameters ensures perfect fit without the need for additional intermediate reducers. Finally, regulatory compliance should be mentioned – production in accordance with standard PN-EN 1254 and designation for medical gas systems (including oxygen and nitrogen) confirm the high quality of this solution.

These parameters make the connector a reliable component in any professional gas installation requiring safety and durability of copper joints. Detailed data regarding pipe diameters (22 mm and 12 mm) and connection types (soldering socket) confirm its dedication to vacuum systems and the distribution of key medical gases such as oxygen and nitrogen.
