Hydraulic Adaptor, 3/8"MB X 1/4"FP

Hydraulic Adaptor, 3/8"MB X 1/4"FP

The 6405X0604 Hydraulic Adapter is a straight hydraulic fitting designed to connect SAE ORB ports to female NPT threaded connections in high-pressure hydraulic systems. Made from durable carbon steel, this adapter provides a strong, reliable transition between hydraulic standards while maintaining a secure seal. The male SAE ORB end uses an O-ring seal for leak-resistant performance, while the female NPT connection allows attachment to tapered pipe-thread components. Rated for up to 4000 PSI, it’s well suited for agricultural, industrial, and equipment hydraulic systems where dependable connections keep everything running smoothly.
