The GRACO 15E539 is a fitting designed to connect 1/4 inch NPSM (National Pipe Straight Mechanical) to 1/8 inch NPT (National Pipe Taper) threads. It is commonly used in fluid handling systems, including paint sprayers and lubrication equipment, to ensure secure and leak-free connections between different pipe sizes. Material is not specified in available sources, but typical GRACO fittings are made from durable metals such as brass or steel for reliable performance in industrial environments.
