WE ARE YOUR GLOBAL PARTNER FOR TOP CONNECTIONS WELCOME TO VULKAN LOKRING VULKAN LOKRING

Sebastian Hackforth Dr. Achim Brodde DEAR CUSTOMER, For more than 30 years now, VULKAN LOKRING’s success has been founded on solder-free tube connection technology for refrigerant lines. Originally developed for the absolute extreme conditions of space technology, we have continually optimised our tube connections for the purposes of refrigeration and air-conditioning technology following takeover of the global patent rights for the tube connection technology, and have since developed into the leading specialist in this area on the world market. In the meantime, more than 1,000,000,000...

3 3 3 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....

STEP 01 | TREAT THE TUBE ENDS 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. Please note the instructions about the use of LOKIN inserts on page 37. 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...

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...

LOKPREP L0w-Temperature (LT) And High -Temperature (HT) 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,...
