The GRACO 557896 Fill Stud is a threaded fitting designed for use in fluid handling systems. It features a 1/4 NPTF (National Pipe Taper Fuel) female thread, making it suitable for connecting hoses or pipes in lubrication and fluid transfer applications. The material is not specified in available sources, but GRACO industrial fittings are typically made from durable metals such as steel or brass for reliability in demanding environments. Its intended use is to provide a secure, leak-resistant connection point within GRACO equipment, particularly in lubrication systems.
