FS6400-06-05 ORFS to O-Ring Stud Straight | Steel Hydraulic Fitting

The FS6400-06-05 ORFS to O-Ring Stud Straight is a straight hydraulic adapter designed to connect Male O-Ring Face Seal (ORFS) systems to Male O-Ring Boss (ORB) stud-style ports in compact hydraulic assemblies. It features an 11/16-16 UNF ORFS male connection (Size 06) on one end and a 1/2-20 UNF ORB male stud connection (Size 05) on the other, ensuring a secure, leak-free transition in medium-pressure hydraulic applications.

Manufactured from high-strength steel and engineered to meet SAE 520120 standards, this adapter provides excellent durability, corrosion resistance, and long service life in demanding industrial, agricultural, construction, and mobile hydraulic environments. The ORFS flat-face sealing combined with ORB O-ring sealing technology ensures reliable leak prevention under vibration, pressure fluctuations, and continuous operation.
