MSS SP-97 Threaded Outlets | NPT Threaded Branch Connections | Stainless Steel, Carbon Steel & Alloy Steel Threaded Outlets
Elite manufactures and supplies high-quality Threaded Outlets, also known as Threadolets, for industrial piping systems. Designed to provide branch connections from a main pipe, these fittings feature a female threaded connection that accommodates a compatible threaded branch pipe or fitting. Threaded Outlets are commonly selected for applications where threaded connections are preferred over welded branch connections.
Elite offers Threaded Outlets in stainless steel, carbon steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Available configurations include standard threaded outlets, reinforced branch connections and flat-base designs, subject to the applicable product specification and installation requirements.
Threaded Outlets are suitable for selected piping applications in oil and gas, chemical processing, power generation, water treatment and general industrial services. They can simplify installation and reduce the need for branch welding where threaded connections are permitted by the applicable piping code and project specification.
