What You Need to Know About LET-LOK Tube Fittings

The HAM-LET Group has been producing its superior, leak-tight LET-LOK® tubing for every kind of system since 1950. Today, the group still leads the market with its brand, which is the most advanced leak-tight tube fitting system available that meets the ever-increasing demand for such fittings especially for industrial standard mechanisms in high-performance, high-pressure and vacuum settings — such as electronics, petrochemicals, fluids, nuclear, power, and other important industrial applications.

LET-LOK® the Leading Brand

The LET-LOK® brand is the ultimate solution for a wide range of industrial applications as they are available in different types of materials. They are also customized to endure high-pressure and severe environments and are the widest range of hi-tech, state-of-the-art industrial-standard mechanisms that efficiently seal and grip tubing. LET-LOK® systems are the result of more than 50 years of energy and time poured in by industry experts in their research, design, development and manufacture.

The Workings of LET-LOK®

LET-LOK® connectors are also very easy to assemble and use. One simply inserts the tube into the full assembly till the tube bottoms-out against the fitting body. The mechanical force resulting from turning the nut clockwise, drives the two ferrules forward between the nut and the fitting body. The back ferrule is then pushed against the front ferrule’s tapered rear and the front ferrule is forced into the tapered mouth of the body. The rear ferrule is then swaged outwardly inwards on the tube while lifting the front ferrule out in order to form a full-faced seal on the tapered surface of the body. Lastly, the 3/4 and 11/4 turn (depending on the size) of the nut from the hand-tight position, ensures tight-proof drive of all the sealing components. This provides additional assurance that the seal will endure high vacuum and high-pressure conditions.

HAM-LET’s Guarantee
