​​​​​​​The LOKRING® Functional Principle

LOKRING®

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 tubecreate a hermetically sealed metal-to-metal connection. 

​The lifetime gas-tightness of the fitted 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 to the tube-joint connection.​

LOKCLIP

LOKCLIP TECHNOLOGY provides you with a simple and low-cost alternative to pressed and screwed connections for hoses. LOKCLIPs can be used to set up both hose-to-hose and hose-to-tube connections for all conceivable repair situations.
The system, comprising stainless steel clips, clip position holder and contoured joint practically excludes application mistakes during assembly. Alongside the important SAE J2064, LOKCLIPs meet all the required standards.​
