Stainless steel union nut - flat sealing

The flat sealing union nuts made from high quality brass and V4A stainless steel from KWS-Industrietechnik are mainly used in the solar industry and heating technology.

The stainless steel (1.4401/1.4408) union nut is available in different sizes:

  • MUINOX038 cylindrical 3/8” female thread, flat sealing, drill hole Ø = 12.6 mm
  • MUINOX050 cylindrical 1/2” female thread, flat sealing, drill hole Ø = 17.1 mm
  • MUINOX075 cylindrical 3/4” female thread, flat sealing, drill hole Ø = 21.8 mm
  • MUINOX100 cylindrical 1” female thread, flat sealing, drill hole Ø = 27.3 mm
  • MUINOX125 cylindrical 1 1/4” female thread, flat sealing, drill hole Ø = 32.6 mm
  • MUINOX150 cylindrical 1 1/2” female thread, flat sealing, drill hole Ø = 41.8 mm
  • MUINOX200 cylindrical 2” female thread, flat sealing, drill hole Ø = 50.3 mm
  • MUINOX250 cylindrical 2 1/2” female thread, flat sealing, drill hole Ø = 50.3 mm

By prefabricating stainless steel corrugated pipes, a flexible connection which makes installations easier can be created using this fitting.

Stainless steel double nipple, flat sealing

The flat sealing double nipples made from high-quality V4A stainless steel (1.4401/1.4408) from KWS-Industrietechnik are available in different sizes:

  • DOINOX038 two-sided cylindrical 3/8” male thread, flat sealing
  • DOINOX050 two-sided cylindrical 1/2” male thread, flat sealing
  • DOINOX075 two-sided cylindrical 3/4” male thread, flat sealing
  • DOINOX100 two-sided cylindrical 1” male thread, flat sealing
  • DOINOX125 two-sided cylindrical 1 1/4” male thread, flat sealing
  • DOINOX150 two-sided cylindrical 1 1/2” male thread, flat sealing


The double nipples are mainly used in the solar industry and heating technology, and have extra-wide sealing surfaces. It is ideal as an intermediate piece, thread union or as a transition for stainless steel corrugated pipes, solar pipes, pipelines and many other applications.

Stainless steel reducer - flat sealing

The flat sealing double nipples made from high-quality V4A stainless steel (1.4401/1.4408) from KWS-Industrietechnik are available in different sizes:

  • RSINOX200150 one-sided cylindrical 2” female thread, one-sided cylindrical 2 1/2” male thread (flat sealing)
  • RSINOX250200 one-sided cylindrical 2 1/2” female thread, one-sided cylindrical 2” male thread (flat sealing)


The reduction pieces are mainly used in the solar industry and heating technology, and have extra-wide sealing surfaces. They are ideal as an intermediate piece, thread union or as a transition for stainless steel corrugated pipes, solar pipes, pipelines, valves and much more.

 

Brass double nipple - conical/flat sealing

This double nipple made from stainless steel from KWS-Industrietechnik seals at one side via a cylindrical thread (flat sealing), whereas the thread at the other side provides a conical seal. Other usage areas are apparatus engineering, mechanical engineering and much more.

Our stainless steel DOKONOX are available in different sizes:

  • DOKONOXO050 one-sided cylindrical 1/2” male thread (flat sealing), one-sided conical 1/2” male thread
  • DOKONOX075 one-sided cylindrical 3/4” male thread (flat sealing), one-sided conical 3/4” male thread
  • DOKONOX100 one-sided cylindrical 1” male thread (flat sealing), one-sided conical 1” male thread

The conical double nipples are mainly used in the solar industry and heating technology, and have extra-wide sealing surfaces. It is ideal as an intermediate piece, thread union or as an adapter for stainless steel corrugated pipes, solar pipes, pipelines and much more.
