A Stainless Steel Male Connector is a type of tube fitting or pipe fitting designed to connect a tube (or pipe) to a female-threaded port. It is widely used in hydraulic, pneumatic, instrumentation, and industrial fluid systems where durable, leak-free, and corrosion-resistant connections are required.
🔧 What It Is:A male connector typically has:
One tube end (for compression or welded tube)
One male-threaded end (for connecting to a female-threaded port, such as NPT or BSP)
There are two main categories:
Compression Male Connector (e.g., Swagelok-type for tubing)
Threaded Pipe Male Connector (used in piping systems)
