Our O-ring face seal female hydraulic fitting adopts precision-machined sealing surfaces and thread profiles, paired with industry-leading sealing designs including 37° flare cone, O-ring groove, and metal-to-metal backup sealing structures. This design delivers exceptional vibration resistance and sealing integrity, with a working pressure range of 3000–6000 PSI (subject to size and configuration), effectively preventing leaks even under sustained high pressure and frequent pressure fluctuations.
Crafted from high-grade carbon steel with a premium zinc-plated finish for superior corrosion and rust resistance, with optional 304/316 stainless steel upgrades available for corrosive operating environments. This heavy-duty material construction ensures extended service life, reducing maintenance frequency and replacement costs for your hydraulic systems.
We offer our high pressure hydraulic female hose fitting in a comprehensive size range from 1/4" to 2" (DN 6–50 mm), with multiple configuration options including straight, 45° elbow, 90° elbow, and 360° swivel styles. The swivel design effectively reduces hose twisting during installation and equipment operation, enhancing hose flexibility and service life in dynamic hydraulic applications.
We provide end-to-end customization services to match your exact hydraulic system needs, including material upgrades, specialized plating options (zinc, chrome, phosphate), custom thread combinations, integrated crimp ferrules, and non-standard angle designs. All custom fittings maintain full compliance with global industry standards while adapting to your specific pressure, fluid, and application requirements.
Our leak-proof ORFS hydraulic fitting is engineered for heavy-duty hydraulic systems across a wide range of industrial sectors, with core applications including construction machinery (excavators, bulldozers, cranes, loaders), agricultural equipment (tractors, harvesters, irrigation hydraulic assemblies), industrial manufacturing (hydraulic presses, injection molding machines, automated production lines), and mobile hydraulic equipment (utility vehicles, forestry machinery, material handling equipment).
