LOKRING BRASS CONNECTORS ® THE TYPICAL LOKRING union joint consists of two LOKRINGs and one tubular joint for the acceptance of the two tube ends. Thanks to the conical inner contour of the LOKRING and the special outer contour of the joint, the diameter of the connection is reduced during assembly to such an extent that the joint and the tube create a hermetically sealed metal-to-metal connection. The lifetime gas-tightness of the tted connection is ensured by the state of permanent elastic pre-tension, which is produced by the radial forces of the LOKRINGs acting in the opposite direction...

POSSIBILITY A Move the nozzle 360° around the tube to distribute the LOKPREP evenly. POSSIBILITY B Rotate the moistened tube through 360° inside the joint. POSSIBILITY C Rotate the joint through 360° around the end of the tube. 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 uid before assembly. Thanks to its capillary characteristic, it can even ow into microscopic cavities and ll these out completely. LOKPREP is not an adhesive, rather an...
