A push nipple is the cast iron fitting that joins adjacent boiler sections together and seals the waterway between them, forming the assembled boiler block.
Can individual burnham boiler sections be replaced?
Yes. Individual front, back, intermediate, and center sections can typically be replaced without swapping the entire boiler, as long as the replacement section matches the original model.
How do I identify which burnham section I need?
The boiler's rating plate lists the model and series, such as V9A or V11, which determines the correct front, back, or intermediate section, push nipple, and hardware needed for the repair.
