Reducer coupling, copper, for medical gases 22-12 MG5240 0221200

Intended Use and Application in Medical Installations

This reducing connector is a key component for safely joining pipes in medical gas distribution systems. It is specifically designed for use with media such as oxygen, nitrogen, carbon dioxide, helium, and medical air, as well as in vacuum installations. Thanks to the use of phosphorus-deoxidized copper (Cu-DHP) with a purity of 99.99%, this material exhibits high corrosion resistance and does not release harmful substances into the flowing gas. This is crucial in hospital environments where medium purity is a priority.

The fitting allows for a smooth transition between pipes of different diameters, which frequently occurs at branch points in installations or when connecting end devices. In this specific model, the reduction is from an outer pipe diameter of 22 mm to 12 mm. Both connection sides are manufactured as push-fit sockets (for soldering), ensuring leak-tightness and durability after capillary soldering.

Construction and Installation Principles

The product is made from high-quality Cu-DHP copper, meeting the requirements of standard PN-EN 1254. This material selection guarantees that the connector is suitable for both soft and hard soldering (with silver addition). For installers, this means flexibility in choosing the joining method depending on the circuit specifics and project requirements. It is important to ensure that pipe ends are properly prepared before installation—cleaned and degreased—which is standard practice when working with medical gases.

It is essential to use solders containing at least 2% silver during hard soldering. This procedure ensures a mechanically strong and pressure-tight joint. These fittings are factory-cleaned and individually packaged, eliminating the risk of internal pipe contamination by dust or grease prior to installation. Dimension markings directly on the product facilitate quick identification during installation work on-site or in hospitals.

Key Technical Features

The most important properties of this connector result directly from its construction: the material is Cu-DHP copper with 99.99% purity, making it corrosion-resistant and safe for medical gases. Universal push-fit socket connections (for soldering) are used on both sides, compliant with standard PN-EN 1057 for copper pipes. The specific feature of this model is the pipeline diameter reduction—from 22 mm to 12 mm—which is ideal for connecting main lines to branches or measuring instruments. The simple (concentric) shape ensures uniform gas flow without turbulence, and the entire product meets the rigorous requirements of standards PN-EN 1254 and PN-EN 13348 for medical gas installations.

Thanks to precise manufacturing and quality control (including hydrocarbon content below 100 mg/m²), this connector is a reliable component in systems requiring the highest standards of safety and reliability.
