Hydraulic Hose Swivel Adapter Fitting, 3/8" NPTF Female to 3/8" JIC Female 37° Flare Straight Connector, SAE J514 Standard 6506-06-06 Carbon Steel for Tractor Industrial Hydraulic Systems (2 Pack)

Standardized Thread Compatibility for Universal Hydraulic Systems This straight hydraulic swivel adapter features a 3/8" Female NPTF (National Pipe Taper Fuel) thread on one end and a 3/8" Female JIC 37° Flare swivel on the other, with -06 size flow capacity fully matching industry standard hydraulic circuits. Manufactured 100% to SAE J514 standards, it guarantees a perfect fit for tapered-to-straight thread conversion in all North American standard hydraulic systems. Heavy-Duty Forged Construction for Extreme Working Conditions Forged from high-tensile carbon steel with a robust industrial zinc plating finish (or stainless steel for enhanced corrosion resistance), this fitting delivers exceptional tensile strength, outstanding resistance to pressure surges up to 5000 PSI, and continuous mechanical vibration. The surface treatment forms a solid anti-rust barrier, ensuring long-term reliable performance even in harsh outdoor construction and agricultural environments. Dual Leak-Proof Sealing Structure for High-Pressure Stability The precision-machined Female NPTF thread creates a mechanical dry-seal connection, while the JIC 37° flare seating forms a tight metal-to-metal seal when mated with standard components. This dual sealing structure locks out fluid leaks even under continuous operating pressures exceeding 3000 PSI, maintaining hydraulic system integrity, reducing fluid loss, and ensuring operational safety. 360° Swivel Design for Effortless Installation & Hose Protection The Female JIC end supports full 360° rotation after tightening, a core design that enables perfect alignment during assembly, eliminates hose torque, and prevents line kinking. This feature greatly reduces installation time in confined spaces, lowers long-term stress on hydraulic hoses, and minimizes the risk of premature hose failure caused by twisting during equipment operation. Wide Application & Rigorous Quality Testing Ideal for construction machinery, mobile hydraulic equipment, agricultural tractors, industrial tools, log splitters, and any application requiring reliable NPTF-to-JIC hydraulic connections. Each fitting undergoes strict dimensional inspection and pressure testing before delivery, with comprehensive after-sales support to ensure your complete satisfaction with every purchase.
