Straight Female ORFS (O-Ring Face Seal) adapters are fittings designed to provide superior leak control in hydraulic systems. The SAE J1453 ORFS connection features a male connector with a straight thread and an O-ring on its face, while the female connector has a straight thread and a flat, machined face. When the male and female parts are connected, the O-ring is compressed against the flat face, creating a secure, leak-proof seal. The threads of the connectors maintain the mechanical connection, ensuring long-lasting, reliable performance. ORFS adapters are known for their excellent sealing properties, making them ideal for high-pressure hydraulic applications where leak prevention is critical.
