When using flared steel tubing in a fluid power system, the fitting used to mate with the tube will have ___________ threads?

When using flared steel tubing in a fluid power system, the fitting used to mate with the tube will have tapered threads. Tapered threads are designed to ensure a tight seal as they are tightened into place. As the fitting is screwed into a corresponding port, the taper allows the threads to compress against the inside of the port, creating a seal that effectively prevents fluid leakage.

The design of tapered threads creates an increasing surface area as the threads engage, enhancing the sealing capability under pressure. This characteristic is particularly important in fluid power applications where maintaining system pressure is essential for proper operation.

Contrastingly, other thread types such as straight threads or specific thread standards like NPT (National Pipe Taper) or beveled threads are not used in the context of flared tubing fittings because they do not provide the same sealing mechanism or compatibility required for effective fluid systems using flared connections.
