The Series 6604 Tee Female JIC Swivel x Female JIC Swivel x Male NPT adapters are robust carbon steel fittings designed for secure, leak-free connections in hydraulic and fluid power systems. These tee adapters feature a three-way design, allowing for the efficient splitting or combining of fluid flow within a system. Both ends are equipped with female JIC swivel connections, which use a 37° tapered seat to ensure a reliable, mechanical seal, while the third end features a male NPT (National Pipe Tapered) connection that provides a tight, leak-proof seal through thread deformation. Made from durable carbon steel, the Series 6604 adapters offer excellent strength, corrosion resistance, and long-lasting performance, making them ideal for high-pressure fluid systems and industrial applications. These adapters are perfect for systems that require dependable, flexible, and efficient fluid routing, providing secure connections for various hydraulic applications.
