A tube plug seals a boiler tube that has failed or is being taken out of service, allowing the boiler to keep running until a full repair is scheduled.
What is the difference between drive in and rod type tube plugs?
Drive-in plugs are tapered and hammered directly into the tube, while rod type plugs use a threaded rod, washer, and nut to draw the plug tight from both ends.
Are tube plugs available in cast iron and wood?
Yes. Drive-in tube plugs come in both cast iron and wood, with sizes ranging from 1/2" up to 3" to match different tube diameters.
