NPT Threaded Unions

The Small Bore Fittings range includes forged carbon steel, stainless steel, and specialty alloy options. Material selection should align with the fluid service, operating environment, pressure requirements, and project specification. Twinco Industrial can help customers identify a suitable material and configuration for process piping, instrumentation, and other industrial applications.

The listed Small Bore Fittings include sizes from ½"–2" and pressure classes from 3000#–6000#. Availability and suitability can vary by fitting type, material, and configuration. Confirm the required size, pressure class, and connection details when requesting a quotation for NPT threaded unions.

The Small Bore Fittings range is identified as compliant with ASME B16.11 and MSS-SP-83. The product information also references the ASME B16 Series and MSS-SP Standards. Customers should confirm the applicable standard and documentation requirements for their specific project before ordering.

Yes. Instrumentation systems are listed among the applications for Twinco Industrial’s Small Bore Fittings. Threaded unions can support maintainable connections where compatible NPT threads, materials, sizes, and pressure classes are specified. Confirm system requirements and applicable engineering standards to ensure the selected union is appropriate for the service.

The Small Bore Fittings range includes both threaded and socket-weld configurations. For an NPT Threaded Union requirement, provide the desired connection type, nominal size, pressure class, material, and application. These details help Twinco Industrial identify the appropriate fitting configuration for the piping or skid assembly.

In addition to unions, the listed range includes elbows, tees, couplings, reducers, caps, bushings, olets, and branch fittings. These options support process piping, instrumentation systems, skid assemblies, and other demanding industrial applications. Product selection should be based on the required geometry, connection type, material, and pressure class.
