06 VULKAN LOKRINGVULKAN LOKRING. LOKRING tube connections and tools are made by VULKAN Lokring in-house: Development, construction,manufacture as well as sales & service. For the customers, this means “all from a single source” and directly from the manufacturer:customised planning and consultancy, supervision at the time of introduction, and support and service locally wherever required.G ERPRE MANENGINCISIONEERINGRESEARCH AND DEVELOPMENT. VULKAN Lokring is the inventor and developer of the patentedLOKRING tube joint. For the last decades, experienced engineers have built new solutions forcustomers‘ applications in the development centre in Germany.PRODUCTION. Approximately 1,000,000 LOKRINGs per day are produced on modern multi-spindleautomatic machines in Germany, Brazil, India, USA and China. Therefore, for customers, LOKRINGis the optimal partner when it comes to safety, flexibility and logistics.QUALITY. The German standard of quality management is the benchmark for the internationalproduction of LOKRING. The certified quality management and the deployment of highly advancedindustrial image processing systems facilitate 100% quality control.SERVICE. Whether you are seeking planning and consultancy for optimising the refrigeration cyclesystem by using braze-free tube connections, support with the introduction of the LOKRINGtechnology in production or after-sales service – everything is available locally with competentVULKAN Lokring technicians.PRODUCT AND MANAGEMENT CERTIFICATION. TÜV and UL product certification. ISO 9001certification of the quality management system. ISO 14001 certification of the environmentmanagement system. AEO certification. Leak-proof tests. Expert survey reports.CLIMATE PROTECTION. Since our tube connections are hermetically sealed, we can ensurethat no climate damaging refrigerants leak into the environment. Furthermore, LOKRINGmakes the use of environmental friendly but flammable refrigerants (HC) safer and allows theuse of CO2 (R744). Thus, by using LOKRING tube connections you make a contribution to theactive protection of the environment.
VULKAN LOKRING 07THE BEST CONNECTION – WORLDWIDE. Operating with five international production facilities, with 17 VULKAN subsidiaries and an additional 13 agenciesworldwide, we ensure that VULKAN Lokring expertise is available on site throughout the world. This means that our customers have rapid access to our specialistsand that the necessary solutions are quickly available exactly where they are needed.VULKAN production facilityCUSTOMER REFERENCES.

These production-relatedfaults can be compensated quite easily by moistening the tube ends to be connected with LOKPREPfluid before assembly. Thanks to its capillary characteristic, it can even flow into microscopiccavities and fill these out completely. LOKPREP is not an adhesive, rather an anaerobic sealantwhich hardens under oxygen exclusion and in contact with free metal ions.
