You should most likely ask the question, why would I replace the tires or muffler on my vehicle?
Put simply, the same reason applies to replacement parts for power tools and pumps. Why scrap the entire product when you can replace a worn part?
Like cars and other machinery, many power tool and pump parts are designed for wear and eventual replacement. The anticipated service life of these products takes the replacement of specific parts into account. Examples of parts that commonly need to be replaced are rotor blades, end plates, cylinders, gaskets, collets, hammers, anvils, pistons and latches.
