Our Series 6504 Straight Male JIC x Female JIC Swivel hydraulic adapters are vital components in hydraulic systems, designed to connect hoses or fittings seamlessly. Constructed from durable carbon steel, these adapters feature a male JIC end that securely attaches to a female JIC fitting, allowing for effective fluid transfer while reducing pressure loss. The swivel design facilitates easy installation and alignment, ensuring a tight fit without twisting hoses. Suitable for a variety of hydraulic applications, Series 6504 adapters improve system performance and reliability, making them an essential choice for professionals in the fluid power industry. Additionally, SAE J514 JIC/37° hydraulic connections are common in most fluid power systems, with both male and female components featuring 37° seats. The seal is created by establishing contact between the male flared and female coned seat, providing a robust mechanical connection that enhances the efficiency of your hydraulic systems.
