USA Industries manufactures header plugs (shoulder plugs) for Fin-Fan^® / air-cooled heat exchanger header boxes. Whether you need 1 or 100, carbon steel or more than 20 other metals, coated or uncoated, we can help fill your needs. We can produce more than 1,000 plugs daily and are available 24/7 to fulfill your order.

Our EZ Torque® Gasket is a revolutionary tool in helping you prevent galling, thread sheer, thread stripping, leaks and more, while requiring less than half the torque of traditional flat gaskets. Switch to using our heat exchanger Kammprofile gaskets today and never have to worry about redrilling a header plug box due to overtightening of a header plug.
