For the last 50 years, the HAM-LET Group has been producing superior-grade, leak-tight tubing for all types of systems. Today, the group still leads the market with its LET-LOK® brand — the most advanced, high-quality leak-tight tube fitting systems available to-date.
More About LET-LOK®
The LET-LOK® brand is a culmination of more than five decades of time and effort invested by leading experts in research, design, development and manufacture of the systems. Now customers can choose from the widest range of state-of-the-art, hi-tech industrial-standard mechanisms that proficiently grip and seal tubing making them the seamless solution for a vast range of industrial applications. The systems are also available in many different kinds of materials for any application.
Let-Lok systems are entirely capable of meeting the fast-growing industry demand for tube fittings that can tolerate use in severe, vacuum, high-performance, and high-pressure environments, such as power, nuclear, fluids, petrochemicals, electronics, and other key industrial applications.
In the Works
LET-LOK® connectors are tailor-made to be very easy to use and just as easy to assemble. Firstly, users insert the tube straight into the entire assembly until the tube bottoms-out against the fitting body. Secondly, the mechanical force resulting from rotating the nut clockwise, drives the two ferrules forward between the fitting body and the nut. Thirdly, the back ferrule is pressed up against the front ferrule’s tapered rear and the front ferrule, in turn, is forced into the body’s tapered mouth. Fourthly, the rear ferrule is swaged outwardly inwards on the tube while raising the front ferrule out in order to form a full-faced seal on the body’s tapered surface. Finally, the 3/4 and 11/4 turn (depending on sizes) of the nut from the hand-tight position, guarantees tight-proof drive of all the sealing components. This provides additional assurance that the seal can tolerate high-vacuum and high-pressure settings.
Our Assurance Guarantee
The HAM-LET group is driven by a core policy of making sure that clients receive a product that is safe. As such, every LET-LOK® connector has endured and passed a series of stringent tolerance tests, including those for vacuum, vibration, impulse, high-pressure, and temperature. Moreover, each connector is crafted by industry experts according to the highest quality-control standards using ultramodern computerized methods. They have more than proved their ability to withstanding all rigorous environments. Furthermore, their ability to remain leak-tight resides in their physical geometry and mechanical advantage.
Upon purchasing a LET-LOK® connector, clients receive a great deal of information and guidelines to make sure their choice is correct for their application. This is another way to ensure that they have supreme outcomes that are safe. It is not only important to select connectors consistent with specific application requirements, but to operate, install, and maintain them properly. To ensure one’s own safety and that of your employees, one also needs to take into consideration material compatibility, application details, and product ratings when choosing a mechanism.
HAM-LET strives to provide every clients with the peace of mind that their LET-LOK® fitting will bring them safety and satisfaction every step of the way.
