Hydraulic Adaptor, 1/4"MP X 1/4"FJX

Hydraulic Adaptor, 1/4"MP X 1/4"FJX

The 6505X0404 Hydraulic Adaptor (1/4" MP x 1/4" FJX) is a straight hydraulic fitting designed to connect male NPT pipe threads to female JIC swivel connections in high-pressure fluid systems. Built from durable carbon steel and rated for working pressures up to 4,500 PSI, this adapter provides a dependable connection between pipe-threaded components and 37° flare hydraulic lines. With a female JIC swivel end for easier installation and alignment, it simplifies hose connections while maintaining a strong, leak-resistant seal—because hydraulic systems work best when the oil stays inside the lines.
