Hydraulic Adapter, 1/2"FS X 5/8"MB

Hydraulic Adapter, 1/2"FS X 5/8"MB

The FS6400X0810 Hydraulic Adapter (1/2" ORFS x 5/8" ORB) is a high-pressure straight hydraulic adapter designed to connect ORFS hose fittings to SAE O-ring boss ports in hydraulic systems. Manufactured from durable carbon steel and rated for working pressures up to 4500 PSI, this fitting provides a reliable, leak-resistant connection between hydraulic hoses and equipment ports. The male ORFS (O-Ring Face Seal) end creates a secure seal against a flat mating surface, while the male SAE O-ring boss end seals inside threaded ports using an O-ring—delivering dependable performance where hydraulic connections need to stay tight and trouble-free.
