O-Ring Face Seal Fittings

We specialize in manufacturing high-pressure hydraulic fittings with O-Ring Face Seal (ORFS) technology. These fittings are designed with unique pressure-bearing capabilities and produced in strict accordance with the international standard ISO8434-3 and the SAE J1453 standard.

Our factory employs a dedicated research team and utilizes specialized tools for machining the grooves of ORFS seals. We also use advanced inspection equipment, including imported Mitutoyo contour meters from Japan, to ensure the highest quality products for our customers.

ORFS fittings are widely used in various industries, including Caterpillar’s engineering machinery and Vestas’ wind power generation industry, due to their superior sealing and pressure-bearing capabilities.
