7 08 VULKAN LOKRING LOKRING ASSEMBLY ONE JOINT, TWO RINGS, FOUR STEPS THAT S ALL THERE IS TO IT. A LOKRING tube connection can be made without a great deal of effort. All you need is a LOKRING tube connection, a hand assembly tool and some LOKPREP. The ergonomic hand assembly tool works without energy connection, and the patented lever mechanism means extremely little strength is needed for assembly. Compare it with conventional tube connection methods for yourself, and you will see that»lokringing«has the potential to become a classic. Where DIY experts have their»rawl plugs«or»flex«-cut materials, you and your customers could be»lokringing«in all sorts of situations. The following illustration is only showing the principle of a LOKRING assembly. Always respect the detailed assembly instructions on THE COMPONENTS OF A LOKRING CONNECTION JOINT The shape of the joint to be used is defined by one of the many types, sizes and repair situations. Lokring When assembled, LOKRINGs guarantee a permanent tube connection. Up to a diameter of 12 mm, the LOKRING tube connection is pre-assembled on the fitting when delivered. 3 3 LOKin Stabilisation inserts bring additional safety into the LOKRING connection and must always be used. 3 Lokprep Thanks to its specially developed properties, LOKPREP secures the lifetime airtight seal of the tube connection. Loktool The hand assembly tool reduces the manual force needed during assembly. The assembly jaws are easy to exchange to match the size of the LOKRING to be fitted.

8 VULKAN LOKRING 09 STEP 01 TREAT THE TUBE ENDS AND USE INSERTS To make a tube connection, the tube ends must be metallic bright and free of longitudinal grooves caused by production. To remedy this, clean the tube ends with our sandpaper or abrasive mats. Always insert stabilisation inserts into the tube ends. Please note the instructions about the use of LOKIN stabilisation inserts on page 37. STEP 02 APPLY LOKPREP Next, moisten the whole tube circumference with LOKPREP by guiding the bottle 360 around the circumference of the tube. Apply the LOKPREP a little away from the cut edge to avoid it getting onto the inside of the tube. Depending on the repair situation, there are several different possibilities of applying LOKPREP over an area see page 11. STEP 03 INSERT TUBES Then insert the tube ends with the LOKPREP film into the joint. Make sure that the ends of the tubes are inserted to the inner limit of the joint and remain fixed in this position during assembly. STEP 04 PRESS Finally, set the assembly tool behind the LOKRING and the assembly stop on the joint and press the LOKRING axially onto the joint until it is flush to the assembly stop that s all there is to it!

9 10 VULKAN LOKRING THE LOKRING FUNCTIONAL PRINCIPLE PATENTED AND free to COMBINATIONS HOW LOKRING WORKs The patented LOKRING tube connection works on the basis of»simple«physical laws. It consists of two LOKRINGs and one tubular joint which takes the two tube ends. During assembly, the tube ends are inserted into the joint to the inner limit. Then an assembly tool is used to push the two LOKRINGs axially onto the joint. Due to the conical inner contour of the LOKRINGs and the special outer and inner contour of the joint, the diameter of the joint is reduced during assembly so that the tube and the joint form a metallichermetic connection through surface contact. The lifetime air-tightness of the fitted connection is guaranteed by the state of permanent elastic pre-tension, which is produced by the balance of the radial forces acting in opposite directions from tube to LOKRING. THE LOKRING MATERIAL COMBINATIONS What can you connect using LOKRING tube connections? There s a simple answer to that: All the metallic tubes commonly used in air-conditioning and refrigeration technology. There is almost no limit to the combination variations here. One rule of thumb is: If at least one of the tubes to be connected is made of aluminium, an aluminium LOKRING must be used as well. In all other cases, a brass LOKRING is used. Always use a heat shrink sleeve for connections between aluminium to copper in order to protect the connection against corrosion. In the case of special tube materials, tube coatings or environmental influences on the material we will be happy to help. MATERIAL ASSIGNMENT Copper Brass Steel Aluminium

10 VULKAN LOKRING 11 lokprep HOW TO MAKE YOUR TUBE CONNECTION PERFECT ALL around. 360 LOKPREP FOR THE TUBE NO WORRIES FOR YOU ALL ROUND. Spreading THE LOKPREP Metal tubes can have longitudinal grooves on the surface from production. These production-related faults can be compensated quite easily by moistening the tube ends to be connected with LOKPREP fluid before assembly. Thanks to its capillary characteristic, it can even flow into microscopic cavities and fill these out completely. LOKPREP is not an adhesive, rather an anaerobic sealant which hardens under oxygen exclusion and in contact with free metal ions. Its elastic structure is permanently retained in a temperature range of -50 to +150 C thus compensating material-specific deformations due to fluctuations in temperature. Since LOKPREP does not contain solvents which have to evaporate during hardening, the finished connection is ready for use shortly after assembly. POSSIBILITY A Rotate the moist tube through 360 inside the joint. POSSIBILITY B Rotate the joint through 360 around the end of the tube. POSSIBILITY C Move the nozzle 360 around the tube to distribute the LOKPREP evenly. LOKPREP L0w-Temperature (LT) And High-Temperature (HT) Since LOKPREP s curing time depends on the ambient temperature, we have developed two fluid types. The curing time of the LOKPREP LT has been optimally matched to ambient temperatures up to 30 C. LOKPREP HT develops its optimum characteristics only at temperatures above 30 C. This gives you maximum assembly flexibility at all times and increases safety at the same time. -10 C 14 F LOKPREP LT up to 30 C / 68 F 0 C 32 F 10 C 50 F 20 C 68 F 30 C 86 F LOKPREP HT from 25 C / 77 F 40 C 104 F 50 C 122 F 60 C 140 F LOKPREP application depending on the ambient temperature in C/ F 70 C 158 F

11 12 VULKAN LOKRING WHEN WE SWAP RINGS, WE RE MAKING A PROMISE. GUARANTEED BY QUALITY CONTROL, TÜV AND UL CERTIFICATE. LOKRING QUALITY AND environmental MANAGEMENT The name VULKAN LOKRING has been standing for top quality for 30 years. Our quality and environmental management system has been certified by the material testing authority in North-Rhine Westphalia according to DIN EN ISO 9001:2008 and DIN EN 14001:2005. To guarantee this quality permanently, we manufacture our LOKRING tube connections using our own production and control procedures. Thanks to highly developed systems for industrial image processing, we manage to carry out dimension tolerance checks on all the LOKRING tube connections produced. As an original equipment manufacturer to the automotive industry, we are used to not making mistakes. MPA NRW.

12 VULKAN LOKRING 13 LOKRING TUBE CONNECTIONS Type-examination tested R134a R290 R404 A R407C R410A R600A TÜV APPROVAL FOR ALL REFRIGERATION SYSTEMS AND HEAT PUMPS The EU standard (EN 378-2), German TÜV (Technical Control Board) and»new«refrigerants such as R 410 A make high demands on tube connections in refrigeration and air-conditioning technology. For the first time, each of these requirements can now be met through a solder-free tube connection. The type-examination tests carried out by the TÜV were not only passed without exception by the LOKRING tube connection, the requirements were even exceeded as far as air-tightness, durability and reliability were concerned. Here is an extract from the tests carried out by the TÜV: Test Requirement Result Leak test Airtight (< 2 x 10 6 mbar l/s helium 4.6) Hermetically sealed Temperature and alternating pressure resistance test Air-tightness after 2600 cycles with temperatures changing between 10 C and 110 C and pressure loads alternating by ± 40 bar during a cycle period of 15 min. Burst test 5 x rated pressure (250 bar) bar (tube burst) Inner pressure threshold test Pressure test Alternating bending test 2 x 10 5 load change from 1 50 bar At least 1.1 x rated pressure (gaseous) 2 x 10 5 load change, inner pressure 50 bar In addition to the comprehensive TÜV tests, the LOKRING tube connection was tested to maximum extreme loads in tensile tests. The result is impressive: The connection can withstand a pullout force of up to 40 kn without any problems. This corresponds to a weight of approx. 4 tonnes, in other words the weight of a fully grown elephant! TECHNICAL FEATURES Hermetically sealed metal/metal tube connection through surface compression, i.e. no O-ring or cutting ring seal. Permanent tube connection according to EU standard EN Purely mechanical tube connection, i.e.»cold«tube connection without thermal method such as soldering or welding. permissible areas of application Operating pressure:* 50 bar with 5-fold safety, i.e. 250 bar.

13 14 VULKAN LOKRING LOKRING RATHER THAN SOLDERING THE BEST CONNECTION FOR REASONS OF SAFETY AND ECONOMY. During the installation and service of refrigeration and airconditioning technology, the connection of refrigerant pipes is one factor critical for success. For decades, soldering was the only albeit unpopular method used for this. Because complex and time-consuming assembly work, potential leaks and soiling were all accepted as part of the package. In other words, soldering is a necessary evil?! Not any more, because the patented LOKRING tube connection now provides you with a procedure that is as absolutely reliable as it is efficient. with LOKRING Solder-free tube connection with TÜV certification Permanent hermetic seal Cost and time savings Assembly possible during business operations No fire protection required Simple assembly without power connection Clean, fast, and customer-friendly

27 28 LOKRING brass reducer adaptors flexibility for all applications become more flexible by reducing your stock The variety of reducing T-connectors and also reducing elbow connectors needed for combining all the different tube diameters which are nowadays being used in air conditioning systems is constantly growing. In order to stay flexible installers needed to build a huge stock of all the different connectors. With the new NRA reducer adaptors VULKAN LOKRING has launched the solution for this problem. You just need the standard T-connectors and standard elbow connectors and make the reduction by connecting the correct NRA adaptor. Thus you will always have the correct connection available directly on-site. Example of use

They support the calibration of the ends of the copper tubes, thus guaranteeing the safe use of LOKRING tube connections. Tensile tests carried out by an independent institute have shown that the pull-out force can be doubled when a stabilisation insert is used.* * Test with hard copper tube (R290) according to EN , ø 35 mm x 1.5 mm

36 LOKRING 37 LOKIN x VH MS y Stabilisation insert LOKIN brass stabilisation inserts* Stabilisation inserts bring additional safety into the LOKRING connection and must always be used. We have developed the LOKIN stabilisation insert especially on account of the increase in refrigerants with higher pressures. In addition to the additional safety component, the stabilisation insert supports the calibration of roll goods. The LOKIN stabilisation inserts must be inserted into the ends of the tubes before LOKRING assembly. 1 pce. * Further sizes available on request. Tube-ø (x) Wall thikness (y) * Article no.

56 loktrace 57 Loktrace find the leak! LOKTRACE gas, which is a mixture of nitrogen and hydrogen, is filled into the system for leak detection. LOKTRACE gas is non-flammable, non-toxic, non-corrosive and not harmful to the environment. Hydrogen molecules are the smallest naturally occurring particles and escape from minimum leaks. With the help of the LOKTRACER TLD.500 or LOKTRACER TLD.1000 the tiniest leaks can be detected. The leak detectors react almost exclusively to hydrogen with nearly no cross-sensitivities to other gases. Further advantages of the Loktrace system Finds even the tiniest leaks < 1 g/year Finds every leak even through screed, insulation and foam No cross-sensitivities no false alarm possible through external gases Can be carried out immediately quickly, precisely and economically Absolutely standard conform with EN , EN and global standards compliant Works independently of refrigerant applicable for any system. THE PERFECT SOLUTION LOKTRACE GAS The smallest and most volatile of all gases 14 times lighter than air Non-combustible, non-toxic, colourless and odourless Suitable for pressure test Climate-neutral and inexpensive CONCLUSION: Loktrace gas finds every single leak! LOktrace COMPARED TO CONVENTIONAL LEAK DETECTION METHODS Finding leaks through insulation Detecting smaller leaks < 1g/year Compliance with legal regulations Reliability Direct implementation Loktrace UV dye Electronic refrigerant leak detectors Vacuum test Nitrogen and bubble spray
