O-Ring Face Seal (ORFS)

O-Ring Face Seal (ORFS)

SAE J5143

The best leak protection available today. The male fitting has a straight thread and O-ring in the face. The female has a straight thread and a machined flat face. The seal takes places by compressing the O-ring onto the flat face of the female, similar to a split flange fitting. The threads hold the connection mechanically.
