Sealing surface of JIC flare connections
In a JIC 37° connection, the primary seal is provided by the mating of matching male and female conical metal surfaces; the thread mainly generates the clamping force. A thread that engages does not show that the conica…

ORFS face seal connections
ORFS is a connection family that seals at the face with an O-ring. The flat face, O-ring groove, mating face and the correct seal work together; a matching thread size alone is not sufficient for a proper assembly.

Series distinction in metric 24-degree connections
In 24° metric connections, the tube diameter, connection type and L/S series information are required in addition to the thread size. The light and heavy series names are not sufficient for selecting by appearance or fo…

Distinguishing a BSP thread from a cone seating surface
A BSP thread identifies only the thread family of the connection; it does not on its own explain whether sealing is achieved with a flat seal, an O-ring, a cone seat or on the thread. For the correct fitting, the thread…

The role of the O-ring in ORB port connections
O-ring boss is a design that seals with an O-ring in a parallel-threaded port connection. Unlike ORFS, sealing occurs in the port area; the port geometry and the seal must both be correct.
