Standard SAE J1453 O-Ring Face Seal (ORFS)
A seal is made when the O-Ring in the male contacts the flat face on the female. Couplings are intended for hydraulic systems where elastomeric seals are acceptable to overcome leakage and leak resistance is crucial. This connection offers the very best leakage control available today.
The male connector has a straight thread and a machined flat face.
The female has a straight thread and a machined flat face. The seal takes place by compressing the O-Ring
onto the flat face of the female, similar to the split fiange type fitting. The threads hoid the connection mechanically.
