Ham-Let (Israel-Canada) Ltd is a supplier of industrial and compression fittings and valves. It is engaged in the development, manufacture and marketing of instrumentation fittings, faucets and valves for industrial command and control systems in a variety of segments.

LET-LOK tube fittings were carefully manufactured to withstand the persistent demands for high-performance fluid systems. Each one passed a stringent tolerance test for high pressure, impulse, vibration, vacuum and temperature. These precision-machined fittings are manufactured to accurate standards, employing the most 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.

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) 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 one and one quarter turn of the nut from the handtight position ensures consistent drive of the sealing members. This ensures an effective seal against high-pressure as well as ultra -high-vacuum conditions.
