The HAM-LET Group has been producing high-quality, leak-tight tubing for every kind of system since 1950. In fact, the group is still leads the market with its LET-LOK® brand – the most high-quality, advanced leak-tight tube fitting systems around.
What is LET-LOK®?
LET-LOK® encompasses a wide range of industrial-standard mechanisms that through their cutting-edge technology effectively seal and grip tubing. Since every industrial application is different, Let-Lok tube and pipe fittings are available in a wide variety of materials. They are also tailored to function in high pressure and severe conditions.
Over the last five decades, industry experts have spent a huge amount of time and effort in researching, designing, developing and manufacturing the Let-Lok systems. As a result, the products are more than able to meet the fast-growing demand for tube fittings that can withstand use in vacuum, high-performance, and high-pressure environments, such as nuclear, fluid, power, petrochemical, electronic, and other key industrial scenarios.
How Does It Work?
When it comes to ease-of-use, look no further than LET-LOK® connectors. They are extremely easy to assemble. First, one simply inserts the tube into the whole assembly until the tube bottoms-out against the fitting body. Secondly, the mechanical force created by rotating the nut clockwise propels the two ferrules forward between the fitting body and the nut by. Thirdly, the back ferrule is pushed against the front ferrule’s tapered rear and the front ferrule is then forced into the tapered mouth of the body. Fourthly, 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. Lastly, the 11/4 and 3/4 turn (depending on sizes) of the nut from the hand-tight position, guarantees fail-proof drive of all the sealing components. This further assures that the seal can withstand ultra-high vacuum conditions and high pressure.
For HAM-LET safety is essential. Each LET-LOK® connector has also undergone and passed a series of severe tolerance tests, including those for impulse, vibration, vacuum, high-pressure, and temperature. Furthermore, the fittings are designed to exacting standards with up-to-the-minute computerized automation. As such, they have proved to be robust enough to withstand all high-pressure conditions. Their ability to be leak-tight lies in their geometry as well as mechanical advantage.
Customers are also provided with ample information and tips to help them select the right product for their application and to ensure maximum outcomes that are both secure and safe. For example, it is recommended for clients operating in the gas industry to choose tubing with greater wall thickness for more efficiency and safety. It is not just vital to select connectors according to specific application requirements, but to correctly install, operate and maintain them. When choosing a connector one should also consider material compatibility, application details, and product ratings to guarantee personal safety.
To further guarantee customer safety and satisfaction, HAM-LET backs all LET-LOK® fittings with a commitment to skilled craftsmanship and the greatest quality-control standards!
