O-Ring Face Seal (SAE J1453)
This connection forms an impressive leak resistance and can be used in applications up to 6000 psi. The male half of the connection has an O-ring with a straight thread. The female half has a machined flat surface with a straight thread. A seal takes place when the O-ring on the male end is squeezed onto the female flat surface seat. The swivel nut on the female half holds the connection together.
