NSC Applied Products Group is a division of NSC that was formed in 2013. We are built on NSC values and the importance of treating customers like friends (because they are).

In 1946, the Nabbefeld brothers began a new venture selling to contractors instead of doing contractor work. National Sales Company (NSC) was founded as a wholesale distributor primarily focused on heating products such as steam traps, radiators, fittings, and pipe. John Nabbefeld used his expertise as a pipefitter and relationships with fellow pipefitters and plumber friends to quickly establish a thriving business. Due to the fact that he was of German descent and the existing political climate post-WW2, John incorporated his U.S. patriotism into the naming the new company National Sales Company and choosing Red, White, & Blue as its company colors.
