The first step in thread identification is to determine whether the thread is tapered or parallel. Tapered means the thread walls, vin continued lengthwise, would eventually meet.

Parallel means the thread walls are straight. A seal must be used for parallel fittings in PORT applications.
Here are some of the different style seals for those PORT applications. The ability to properly identify seats, chamfers and their corresponding angles is a benefit to the fitting identification. To achieve a tube connection, a tube nut is tightened over the metric threads forcing a ferrule or cutting ring to grip the tube.
382-2 the nut is securely fastened, the ferrule squeezes the tube which holds the tube in place. Essentially, face seal fittings seal between an O-ring located in the face of the straight male thread, and the flat face seat on the female thread.
After identifying if the threads are parallel or tapered, measure the thread pitch in millimeters over the top of the thread crests. BSP threads come in two versions: This can be verified vin a thread gauge. This is why it comes in Imperial sizes: Use a calipers to measure the outside diameter OD of the threads.

On taper threads it is important to place the calipers on the 3rd row of threads. Metric thread call out is the OD in millimeters followed by the pitch. BSP fittings can be identified by completing a few calculations to dib the thread size.
Once you have the thread size, it is important to verify the pitch. The easiest way is to follow the following steps.

Measuring Threads After identifying if the threads are parallel or tapered, measure the thread pitch in millimeters over the top of the thread crests.
Thread sealant tape is recommended for a leak free connection. The female has a straight thread and a tapered ball or cone seal seat.

The seal takes place between the chamfer idn the male and ball or cone of the tapered seal flareless swivel. The threads hold the connection mechanically.
The female port has a straight metric thread, a machined surface and a chamfer to accept the O-Ring. The seal is created by compressing the O-Ring into the chamfer. The seal is created by establishing a line of contact between the male nose and the female flare. Male Thread OD inch. Female Thread ID inch.
