O-Ring Face Seal (SAE J1453 ORS/ORFS)
Identification
Male fitting has a straight thread and an O-ring. Female
has a straight thread and a machined flat face.
Seal
The seal takes place by compressing the O-ring onto the
flat face of the female. The threads hold the connection
mechanically.
Application
Fittings are intended for hydraulic systems where
elastomeric seals are accepted to overcome leakage
and leak resistance. This connection offers the very best
leakage control.
