The Series 6068 Straight Rigid Male ORFS x Male Metric Hydraulic Adapter with Washer & O-Ring is designed for secure, leak-proof connections in hydraulic systems. It combines the O-Ring Face Seal (ORFS) technology, which utilizes an O-ring positioned on the face of the fitting to create a strong, elastomeric seal when tightened. The male ORFS end provides a flat sealing surface, while the male metric threads, commonly used in European systems, feature a specific millimeter-based measurement for the outer diameter and thread pitch, such as M22x1.5. This adapter includes both a washer and an O-ring, ensuring a tight, reliable seal by compressing the O-ring against the flat face of the mating fitting or tube. ORFS adapters are often made from high-quality materials like carbon steel or stainless steel, making them ideal for demanding applications requiring high pressure and durability.
