Fitting of Union Connector Union Connector Products Found: 181 LET-LOK® HOW DOES IT WORK? The LET-LOK0 tube fitting is a mechanism used both to seal and to grip tubing. The mechanicaJ advantage and geometry of this kind of fitting produces a leak-tight assembly. To assemble, simply msert the tube into the complété assembly until the tube bottoms out against the shoulder of the fitting body (1). The two ferrules are driven forward between the nut (4) and fitting body using the mechanicaJ force created by rotating the nut clockwise. The back ferrule (3) is driven against the tapered rear of the front ferrule (2) and the front ferrule is dnven by force into the tapered mouth of the body. The rear ferrule is swaged radially inwards on the tube while lifting the front ferrule out to form a full-faced seal on the tapered surface of the body. The one and one quater turn of the nut from the hand-tight position assures consistent drive of the sealing members. This ensures an effective seal against high-pressure as well as ultra high-vacuum conditions. As a resuit of tremendous efforts In research and development during the last five décades. HAM-LET has gained an excellent réputation as a leading manufacturer of high-pressure instrumentation products. The LET-LOK* range of connectors has been developed to fill the rapidly increasmg demand for tube fittings suitable for high-pressure use in environments such as petrochemical. fluid. power. nuclear. electronic. as well as other major industrial settings.
