The Series 6503 90-Degree Female NPT x Female JIC Swivel adapters are high-performance carbon steel fittings designed to provide secure, leak-free connections in hydraulic systems. Featuring a 90-degree angle, these adapters are ideal for efficiently routing hoses and pipes in tight or confined spaces. One end is equipped with a female NPT (National Pipe Tapered) thread, which creates a tight, leak-proof seal by deforming the tapered threads, while the other end features a female JIC (Joint Industry Council) connection with a 37° tapered seat, ensuring a reliable, leak-tight seal. The swivel feature allows for flexible installation, making it easy to adjust the adapter into the desired position. Made from durable carbon steel, the Series 6503 offers excellent strength, corrosion resistance, and long-lasting performance, making it perfect for high-pressure fluid power systems and industrial applications that require reliable, flexible, and efficient connections.
