The values of safety, excellence and respect drive everything that STEMCO and parent company EnPro Industries (NYSE: NPO) do.

  • Trust, training, support, and focused innovation are just a few of our value drivers at STEMCO. Increasing fleet safety, performance expectations, ROI and fuel efficiency are our specialties – and with over 21 new product launches in the last five years alone, customer driven solutions are helping to drive innovation.
  • STEMCO’s TrailerTail® for semi-truck trailers increases fuel efficiency by 5.5% and improves stability and visibility, increasing both safety and peace of mind. The patented award-winning technology streamlines airflow at the back of the trailer to reduce the low-pressure vacuum that creates rear drag and decreased fuel efficiency — and it does so without hindering trailer cargo capacity, loading or  unloading. 
  • Ornit provides special designed fasteners for airflow wings connection to body frame trailer.
