Tube Fittings - High Pressure Applications

Tube fittings, HAM-LET® GROUP has produced high quality tube fittings for high pressure applications since in 1950. A leading tube fittings manucaturer for five decades, Ham-Let tube fittings are the result of tremendous research and development efforts. HAMLET® has earned an excellent reputation as a leading manufacturer of high pressure instrumentation products and tube fittings. The coompany's LET-LOK® line of connectors has been developed to fill the increasing demand for tube fittings suitable for high pressure use in petrochemical, fluid, power, nuclear, electronic and other major industries.

LET-LOK® tube fittings have been carefully manufactured and tested to withstand the demands of high performance tube fittings such as high pressure, impulse, vibration, vacuum and temperature. These Ham-Let tube fittings are manufactured to exacting tolerances using advanced computerized automation. One of the main conditions required for producing these precision machined tube fittings is stringent quality control in conjunction with skilled craftsmen.

The Principle - Tube Fittings
ONE-LOK tube fittings are 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. Ham-Let's tube fittings are designed for use in control systems, process and instrumentation devices and in industrial equipment used in various industries such as:
• Pulp & paper mills
• Petroleum process plants
• Chemical process plants
• Chromatography
• Power generation plants

Tube Fittings Remake Ability
ONE-LOK fittings are engineered to the highest standards and have been tested to bursting pressure with both maximum and minimum wall thickness. Correctly assembled ONE-LOK tube fittings were installed and no leaks or other failures were noted at the connection points. The Ham-let Technical Department offers advice regarding appropriate working pressure for its ONE-LOK tube fittings. ONE-LOK tube fittings are supplied assembled, finger tight. Disassembly of ONE-LOK tube fittings before use can allow the entry of dirt or other particles. ONE-LOK tube fittings connections may be disconnected and remade repeatedly, without loss of leaktight seal.
