Because the high temperature will be generated during the torch welding ,and the high temperature is easy to burn the plastic parts and other electrical parts, and especially,aluminum tube will be slowly oxidized after a period of time because of the high temperature from the welding torch, it results in recurrence of trachoma leaks. It not only wastes time to repair,but also is not easy to weld again. A good news is that there is a welding-free tools tool named lokring with which, the high temperature from torch fire welding could be avoid, and vacuum and fluorine can be added immediately after crimping complete, no need to wait.
With this professional tool kit, welding is not required when repair the refrigerator or replace the refrigerated evaporator or deal with problems such as internal leakage of the machine’s refrigerated back,also includes to repair the air conditioner pipe system,which way can avoid damages other parts because of the inappropriate using welding torch or the high temperature from torch welding. Just use this crimping pliers to directly press the copper, aluminum or iron connectors, which is suitable for all brands of refrigerator or air conditioners repairs. The repair speed with this welding-free tools is at least 2 times faster than that with manual welding,also is more safe because no producing high temperature. After all, it is most important to improve working efficiency and safety quality. Lokring tools adopts the technology of leak-free sealing by cold extrusion,it not only let working effiency improves much,but also having more excellent sealing quality than that by traditional torch soldering welding,is becoming the new technology in the field of HVAC project.

Sealant for lokring technolgy
Sealant SUP: filled tiny scratch on the surface of metal tubes to ensure complete seal. It is unavoidable to occur axial scratches on the surface of metal tubes during extruding or drawing the cooper tubes, AL tubes, and TI alloy tubes. These could not be completely sealed by mechanical deformation. SUP sealant is use to fill those tiny scratches. SUP Sealant is mainly used together with above complex rings and composite rings. SUP sealant will fill the scratch and solidify during installation of connectors, to form a perfect seal application. SUP has better elasticity and ductility after solidification. In the specific temperature range, it will form a soft membrane to make good seal effect. SUP is anaerobic liquid,containing methacrylate. It will strengthen with epoxide without of solvent evaporation.
SUP sealant and other kinds of sealant have already been accepted by almost all industries. It can be applied to gas tubes, drinking water tubes and refrigerator tubes. SUP sealant can reduce electrochemical corrosion, such as cooper & aluminum, cooper & Ti, cooper & iron, etc. SUP sealant will form a protection membrane between two different metals to minimize the contact surface, which will slowdown the electrochemical corrosion process and ensure safe operation of pipes during their designed working life.
Usage amount of SUP: apply in even coating on the surface of the end of the pipe to be connected.
Selection of sealant: Temp -50°C ~ 150°C , Applied to common refrigeration system; Temp -50°C ~150°C , Applied to common refrigeration system; Temp -50°C ~ 220°C , Applied to solar energy tubes; Temp -50°C~150°C , Applied to common refrigeration system.

General Knowledge on “Vulkan Lokring"
Vulkan lokring is specially designed for HVACR project work,to connect copper pipe or aliminium pipe,using as installation and Service Tools in refrigerating field. It save your trouble to take welding tools and save your cost of employ prfessional welding workers by using only one vulkan lokring tool + glue + connector. 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.
They are very effective and 99% leak proof,and can improve 300% quicker than welding without potential issues and leaks. You just need to insert into each pipe, glue the outside of the pipe and use the tool to tighten both sides together, this makes a seal and the “weld” is done by the glue and tool. It ensures we use less 90 degree joints in the system to ensure better flow through,and can stand for gas and high pressure without leak. Vulkan lokring complex ring is key unit of tubes connection in refrigeration system.Easy to use,high efficient,safe,reliable and has been widely used in refrigerators, airconditioning installation and maintenance, seafood machine of installation and maintenance, dryer repair, refrigerator installation, locomotive airconditioning repair, installation of flat panel solar energy, installation of heat pump. vulkan lokring complex ring can completely replace the traditional flame welding,improve the efficiency , simplify work process,reduce the equipment that need to carry,and improve the quality of connection in refrigeration system installation/repair. Particularly in complex tubes connection with commercial airconditioning,the suhring complex ring can achieve the perfect standard work,high efficiency,high quality,nice engineering.
In the supermarket,about the maintenance of commercial facilities, the traditional flame welding can not match the suhring complex ring,because the complex ring is convenience,fast,and no-fire connection,,and do the connection work anytime,not until the supermarket closed,not affect the business,just need a simple tool,some suhrings, a bottle sealing liquid,finish the tubes connection of commercial facilities within 10 minutes. Note: The maximum thickness of tube wall is 2mm The maximum working pressure PN = 50bar The maximum burst pressure testing Pp = 4PN = 200bar The temperature range is -50 ° C ~ +150 ° C (or 220 ° C) The suhring complex ring can be used in round tube with any material. Application aera: Airconditioning installation: save time, improve efficiency, reduce leakage rate of welding, to avoid electrochemical corrosion 1,Seafood machine production/installation: lower costs, reduce the leakage rate of welding, to avoid electrochemical corrosion 2,Automotive airconditioning: lower costs, reduce weight, reduce leakage rate of welding 3,Motor-car airconditioning: lower costs, reduce weight, reduce leakage rate of welding 4,Refrigerator (freezer) Maintenance: To improve service quality, simplify operations, to avoid electrochemical corrosion 5,Commercial Display Cases maintenance : no need to wait,any time can to do, improve efficiency, and create benefit 6,Multi-line commercial airconditioning installation, maintenance: save time, lower costs, reduce the leakage rate of welding Other: Be used specialized tubes connetor in HVAC, domestic water, drinking water with aluminium,plastic、PPR tubes.
