1. Let-Lok Tube Fittings

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.

The LET-LOK® range of connectors has been developed to fill the
rapidly increasing demand for tube fittings suitable for high pressure
use in environments such as petrochemical, fluid, power, nuclear,
electronic, as well as other major industrial settings.

LET-LOK® tube fittings have been carefully manufactured to withstand
the persistent demands for high-performance tube fittings. Each one
has passed a stringent tolerance test for high pressure, impulse,
vibration, vacuum and temperature. These precision-machined
fittings are manufactured to exacting standards, employing the most
modern 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.

2. One-Lok Tube Fittings

HAM-LET ONE-LOK® is designed to provide leak-proof, secure
connections that can withstand high pressure, vibration and
vacuum applications. To this end, ONE-LOK® tube fittings
are made up of three parts that are precision engineered and
machined: body, ferrule and nut.

ONE-LOK® is designed for use in control systems, process and
instrumentation devices and in industrial equipment used in
various applications. For example:

• Pulp & paper mills
• Petroleum process plants
• Chemical process plants
• Chromatography
• Power generation plants
• ONE-LOK® offers a simple, high-quality tube fitting with excellent
  performance and reliability.

ONE-LOK® standard single-ferrule fittings are offered in 316
Stainless Steel. Cold-drawn finished bar stock is machined to
produce the straight fittings. Close-grain forgings are used for
the machining of the shaped bodies.

3. Dielectric Fitting

Dielectric fittings and adapters protect the accuracy of monitoring instruments by isolating the instruments from the effects of electrical currents and maintaining full fluid flow.
