USA Industries manufactures Header Plugs (Shoulder Plugs) and gaskets for Fin-FanĀ® / air-cooled heat exchanger header boxes.Ā Our revolutionary EZ TorqueĀ® Gasket helps prevent galling, thread sheer, thread stripping, leaks and more, while requiring less than half the torque of traditional flat gaskets. With our Kammprofile Gaskets (also called Camprofile Gaskets) you'll never worry about redrilling a header plug box due to overtightening of a header plug.
