LOKRING tube connections can be manufactured without a great deal of effort using simple hand assembly tools and guarantee an absolutely clean, indissoluble and purely mechanical pipe connection with a permanent hermetic seal. LOKRING is one of the most economic and reliable methods to connect refrigerant pipelines.

LOKRING tube connections are used in the production of refrigerators and freezers, air conditioning units and heat pumps, in the installation and repair of refrigeration plants and air conditioning units and vehicle air conditioning units and in the repair of household devices and small refrigerating machines.

LOKRING tube connections are a preferred alternative to soldering as they are more cost effective, provide a better quality with lower failure and leakage rates and also save time on every connection. They also offer the option of converting pipes and components in the cycle into cost-saving substances (e.g. aluminium).

LOKRING directly saves costs for silver solder and trained staff. In addition to this, LOKRING often reduces subsequent costs of soldering such as leaky points, corrosion, harmful vapours, damage, burns and pipe preparation. LOKRING can even decrease the number of connections which are necessary and the use of expensive copper components.

A correctly implemented LOKRING pipe connection ensures absolute freedom from failures and impermeability both in the plant and in the field.

Using LOKRING SINGLE RING TECHNOLOGY, refrigerant pipes made of metal can be combined such that they are permanently hermetically sealed. VULKAN Lokring uses raw materials, dimensions and tolerances to construct customer-specific LOKRING tube connections and the corresponding assembly tools for any application. The main area of use is the refrigeration circuit in the series production of refrigerators and freezers.

This technology is also used in evaporators for vehicle air conditioning units, in heat exchangers for heating and cooling technology (e.g. the production of heat pumps) or in the series assembly of cooling and air conditioning technology (e.g. air conditioning systems for buses). Whether you’re looking for cost optimisation, an improvement in quality or a solution to a customer-specific problem – LOKRING SINGLE RING is the answer!

VULKAN Lokring has been a supplier to all leading manufacturers of refrigerators and freezers for more than 36 years. During this time, more than 1,500,000,000 LOKRING® tube connections have successfully been installed in the industrial series production of refrigerators, freezers and vehicle air conditioning units.
