The Series FS6565 Straight Female ORFS Swivel x Female ORFS Swivel adapters are high-quality fittings designed to provide excellent leak prevention in hydraulic systems. Featuring SAE J1453 O-Ring Face Seal (ORFS) connections, these adapters have a female connector on both ends, each with straight threads and a machined flat face. The male counterpart, with a straight thread and an O-ring on its face, ensures a secure, leak-free seal when the O-ring is compressed against the flat face of the female part. The swivel design allows for easier alignment and installation. Known for their strong sealing properties, these adapters are ideal for high-pressure applications where reliable, long-lasting connections are critical for performance.
