Protecting our planet is of key importance to us all.

Most developed and developing nations around the world have implemented strict regulations to reduce exhaust emissions of every kind. This has spawned several new industries, not least of which are the new emissions control technologies for trucks and automobiles. Seglian has been serving the Emissions Control industry since 2002, during the early implementations of regulatory policy in the USA and Europe.

We manufacture a wide range of production components for:

  • Exhaust Gas Recirculation / Cooling (EGR)
  • Diesel Particulate Filters (DPF)
  • Selective Catalytic Reduction (SCR)

Our Products include:

  • Stainless steel, precision, corrugated gas tubes for EGR
  • Stainless steel machined investment castings for EGR and other
