The Series 6603 Tee Female JIC Swivel x Female JIC Swivel x Male JIC rigid adapters are high-quality carbon steel fittings designed to provide secure, leak-free connections in hydraulic systems. These tee adapters feature a three-way design, making them ideal for splitting or combining fluid flow in a system. The adapter includes female JIC swivel connections on two sides and a male JIC connection on the third, allowing for easy routing and flexibility in fluid power systems. The swivel feature on the female connections allows for easy installation and adjustment, ensuring proper alignment without compromising the seal.
