The 3 304 Stainless Steel Machined Half Coupling - SP114 is a pipe fitting used to connect a branch pipe to a main pipeline, providing a secure and reliable connection. Unlike a full coupling, it features one full threaded end for attachment to a pipe or fitting and a reduced stub end designed for welding, screwing, or mounting to the main pipeline. This fitting provides a weld-on threaded outlet for branch connections, creates robust threaded ports on tanks or piping, and supports compact flow paths with minimal footprint. Constructed to MSS Class 150 stainless steel standards and featuring ASME B1.20.1 NPT threads, it ensures compatibility with standard piping systems and long-lasting performance.
