USA Industries is the go-to company for several of the world's largest power plants, refineries, and chemical facilities for header plugs or shoulder plugs. We pride ourselves on our rapid production capabilities, quick turnaround times, and flexbility to produce our plugs in almost any combination of metals (carbon steel, stainless steel, copper and brass are standard), coatings (cadmium, electroless nickel, galvanized, nickel, zinc or uncoated) and size.

For the world's largest industrial facilities, keeping a shutdown or turnaround on hold for a small part of a heat exchanger doesn't add up. We're able to produce more than 1,000 header plugs / shoulder plugs daily for your fin-fan (air-cooled heat exchanger) at a high quality, to your exacting specs and ship them out 24/7!

The next time you need plugs for your fin-fan (air-cooled heat exchanger), contact USA Industries. In-stock plugs and gaskets ship the same day!
