Tube fittings probably aren’t something you think about every day, at least, not until something breaks. And when that something breaks, you want to be certain you have the replacements on-hand that can do the job.
Interchangeable with other systems for complete flexibility
DK-Lok tube fittings are truly universal and easily swaps out with other brands, and are designed using industrial codes and specifications through cutting-edge engineering on swaging action and sealing. Reliably leak-free sealing on high pressure gas, vacuum, impulse, thermal shock, cryogenic, heavy vibration and other highly-taxing applications.
The full range of material options
DK-Lok fittings are available in a wide range of materials to suit practically any application, from oil and gas (onshore and offshore), chemical, petrochemical, analytical instrumentation, steel mill, power plant, shipbuilding, pharmaceutical and alternative fuel. Available in stainless steel 316, brass, carbon steel, duplex, super duplex, aluminum, titanium, PTFE and a range of alloys, DK-Lok fittings are also cleaned to remove any surface contamination and are available cleaned for oxygen service.
Highest-quality construction for the best performance
All DK-Lok Tube Fittings feature leak-free sealing integrity intended to withstand the demands of heavy vibration, vacuum and impulse applications, with additional engineering specific to swaging action. They’re designed so that no torque transfers to the connective tubing during installation, and are heat-code traceable. Built in the United States, DK-Lok fittings are machined in Huntsville, Alabama.
