Tube fittings

Tube fittings – the elements of pipelines, providing pressure tight joints between tubes of same or different diameters, branch out and turn pipelines in any directions. Tube connections can be detachable (tube fittings and adaptors) and non-detachable (welded).

Advantages of tube fittings

Connection of tubes by using adaptors has several advantages, in particular:
  • Easy assembly and further repair of the pipeline;
  • Reliability and leak resistance;
  • Upgradeability;
  • Opportunity of pre-assembling and installation in hard-to-reach places, as well as in dangerous spaces;
  • Wide range of tube fittings affords to assemble any complex hydraulic system;
  • Esthetic view of pipelines;
  • No need to have qualified welders in staff;
  • No need to carry out X-ray control after assembling.
Tube fittings according to DIN 3859-1 are produced from drawn or forged steel, according to DIN 3859 – from yellow metal, acid-resistance or heat-resistance steel, maintaining structural solidity for decades. Zink and chrome electroplating  protects the external fitting’s surface from environmental factors.
