3/4" Let-Lok Tube Plug Twin Ferrule Ham-Let Group has a wide range of fittings made of various materials, with temperature and pressure ratings across the board. Ham-Let Group fittings are leak resistant and used in many industries. All HAM-LET fittings are certified to be interchangeable and intermixable with Swagelok, Hoke Gyrolok, Parker A-lok etc range of fittings.The HAM-LET Group has produced high quality tube and pipe fittings in various materials for high-pressure applications since its establishment in 1950. As a result of tremendous efforts in research and development during the last five decades, HAM-LET has gained an excellent reputation as a leading manufacturer of high-pressure instrumentation products. The LET-LOK® range of connectors has been developed to fill the rapidly increasing 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. LET-LOK® tube fittings have been carefully manufactured to withstand the persistent demands for high-performance tube fittings. Each one has passed a stringent tolerance test for high pressure, impulse, vibration, vacuum and temperature. These precision-machined fittings are manufactured to exacting standards, employing the most modern state-of-the-art computerized automation. All LET-LOK® fittings are backed by HAM-LET‘s commitment to the highest quality-control standards and skilled craftsmanship. How does LET-LOK® work? The LET-LOK® tube fitting is a mechanism used both to seal and to grip tubing. The mechanical advantage and geometry of this kind of fitting produces a leak-tight assembly. To assemble, simply insert the tube into the complete 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 mechanical 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 driven 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 1 and 1/4 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.
