LET-LOK Tube Fitting Mechanisms

LET-LOKŪ encompasses a vast range of industrial-standard mechanisms. With leading-edge technology, they are able to professionally seal and grip almost any tubing.

Since 1950, the HAM-LET Group has been leading the market with its high-quality, leak-tight tubing for all types of systems. In fact, the LET-LOKŪ brand offers the most superior and progressive leak-tight tube fitting systems available on the market.

What’s LET-LOKŪ?

LET-LOKŪ comprises an extensive variety of industrial-standard mechanisms. Thanks to their cutting-edge technology, these mechanisms efficiently grip and seal tubing. Additionally, to accommodate the differences between each industrial application, Let-Lok pipe and tube fittings are offered in a range of materials. They are also tailor-made to function in severe and high-pressure settings.

Over the past 50 years, industry experts have invested a great amount of time and energy in investigating, designing, creating and manufacturing these systems. The results are products that are geared to meet the fast-increasing demand for tube fittings that can endure use in high-performance, high-pressure and vacuum environments, for example petrochemical, power, nuclear, fluid, electronic, and other strategic industrial scenarios.

How Does LET-LOKŪ Operate?

LET-LOKŪ connectors are game changers as far as ease-of-use is concerned and are exceptionally easy to assemble. One only has to insert the tube into the full assembly until the tube bottoms-out against the fitting body. Next, by rotating the nut clockwise the mechanical force created drives the two ferrules forward between the nut and the fitting body.

The posterior ferrule is then pushed against the anterior ferrule’s tapered back and the anterior ferrule is then forced into the tapered mouth of the body. The posterior ferrule is radially swaged inwards on the tube, while raising the anterior ferrule out to form a full-faced seal on the tapered surface of the body. Finally, the 11/4 and 3/4 turn (depending on the size) of the nut from the hand-tight position, ensures faultless drive of all the sealing components. This provides additional assurance that the seal is able to survive high pressure and ultra-high vacuum conditions.

Guaranteed Safety

For HAM-LET, safety is a crucial factor and every single LET-LOKŪ connector has endured and passed severe tolerance tests, including for vibration, high-pressure, impulse, temperature, and vacuum. The fittings themselves are designed to rigorous criteria with state-of-the-art computerized automation. This means they have proved to be tough enough to withstand all strenuous conditions. Also, their geometry and mechanical advantage enable them to remain leak-tight.

Clients also receive abundant material and guidelines to help them choose the correct product for their application and to guarantee maximum outcomes that are safe and secure. It is, for example, strongly recommended that clients in the gas industry choose tubing with a greater wall thickness for increased safety as well as efficiency. It is not only crucial to choose connectors according to one’s specific requirements, but to correctly install, work and preserve them.

To further ensure personal safety, when selecting a connector one should also take application details, material compatibilityFree Articles, and product ratings into consideration.
HAM-LET further ensures customer satisfaction and safety by backing all its LET-LOKŪ fittings with an assurance of the utmost quality-control standards as well as expert craftsmanship!
