Iron Fittings These are widely used in construction, serving well as connecting hot and cold water pipes. Therefore, they are ideal for:

  • Residential construction;
  • Building construction;
  • Gas systems;
  • Fire fighting systems;
  • Between others.

Iron fittings are available in several options, including BSP, NPT MP, and NPT AP. They vary in size and purpose. These models can be classified according to their technical capabilities. See:

  • Gloves;
  • Tests;
  • Cross arms;
  • Bushings;
  • Plugs;
  • Tampons;
  • Elbows;
  • Water Tank Adapter;
  • Double Nipples;
  • Tubes for Hydrometers;
  • Locknuts;
  • Unions;
  • Between others.

Forged Fittings These are widely used in small-diameter pipes, common in compressed gas, water, air, and steam systems. Forged fittings are ideal for withstanding low pressure. They are connected using threads that connect to the pipes. The distinguishing feature of this type of thread is its resistance. It is a material commonly found in industrial environments, such as:

  • Oil refining segment;
  • Pulp and paper;
  • Industrial assemblies;
  • Chemical industries;
  • Steel mills;
  • Construction sites;
  • Between others.

Forged fittings are available in several options, each with different dimensions and purposes. These models can be classified according to their technical capabilities. See:

  • With Thread/Elbow;
  • With Thread/Plugs and Bushings;
  • With Thread/Glove-Half Glove;
  • With Thread/Union;
  • Socket/Elbow;
  • Socket/Glove-Half Glove;
  • Socket/Union.

Tubular Connections These are widely used in industry for engineering projects. Tubular connections are used for conduction in outdoor areas. Tubular connections are very common in various industrial segments, such as:

  • Refineries;
  • Oil industry;
  • Natural gas;
  • Pulp and paper;
  • Heating of materials;
  • Shipbuilding;
  • Metallurgical sector;
  • Energy sector;
  • Between others.

Tubular fittings are available in several options, each with different dimensions and purposes. These models can be classified according to their technical capabilities. See:

  • Concentric and Eccentric Reduction;
  • TEE 90°;
  • TE 45°;
  • Cap – Cap;
  • Concentric and Eccentric Reducing Nipple;
  • Long Threaded or Weld Nipple;
  • 45° 90° 180° Curve – Long Radius;
  • 90° 180° Curve – Short Radius;
  • Short Eyelash;
  • MSS Eyelash;
  • Stub End (Long).
