Compression Tube Fittings
DK-Lok Tube Compression Tube Fittings are designed using industrial codes and specifications with additional Cutting-Edge Engineering on swaging action and sealing integrity. DK-Lok provides excellent leak-free sealing on high-pressure gas, vacuum, impulse, thermal shock, heavy vibration, and many other stringent applications. DK-Lok brings you truly excellent quality, outstanding customer service, and availability.
DK-Lok Compression Tube Fittings are supplied in numerous materials to satisfy the needs of various applications including on shore oil & gas, refinery, offshore oil& gas, chemical, petrochemical, analytical instrumentation, steel mill, power plant, shipbuilding, pharmaceutical, and alternative fuel.
DK-Lok compression tube fittings are designed for a wide range of leak-free applications including gas leak proof and vacuum-tight services. Gases (helium, hydrogen, nitrogen, air, etc.) can escape even the smallest leak-path due to their very tiny molecules. Therefore, there can be no nicks or contamination when manufacturing the compression fittings.
DK-Lok Tube Fittings consist of body, front ferrule, back ferrule, and
nut. The features include:
- Excellent product range up to 2 in. and 50 mm OD.
- Additional engineering on sealing integrity and swaging action.
- Re-usable and predictable quality.
- Excellent leak-free sealing integrity on heavy vibration, vacuum, and impulse.
- Heat-Code Traceability.
- No torque transferring to connective tubing during installation
Metric DK-Lok tube fitting has stepped shoulder on the body and nut hex. A shaped fitting such as tee, elbow, and cross forging has such a step on the body as well.
