Midland Industries SS5405-32-32 Pipe Expander 2in Nptf

Product Description

The MIDLAND INDUSTRIES SS5405-32-32 is a stainless steel pipe expander fitting designed to transition between a 2-inch male NPTF connection and a 2-inch female NPTF connection within a piping system. Constructed from 316 stainless steel, this adapter is rated for a maximum operating pressure of 3900 psig and can handle operating temperatures up to 1000 degrees F. At 2.66 inches in length, it provides a compact inline solution for expanding flow paths or adapting thread orientations without adding excessive bulk to an assembly. Plumbers, pipefitters, and mechanical contractors working on high-pressure or high-temperature systems rely on this type of fitting to maintain sealed, threaded connections in demanding service environments.

This fitting is suited for use in industrial piping, process systems, and high-temperature fluid handling applications where corrosion resistance is a priority. The 316 stainless steel construction makes it appropriate for use with aggressive media, marine environments, chemical processing lines, and steam service. The NPTF thread form provides a pressure-tight seal relying on thread interference rather than a separate sealant, which is critical in high-pressure installations. Professionals installing this adapter should verify that mating pipe threads conform to NPTF specifications to achieve proper sealing performance.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and high-temperature environments
• Rated to 3900 psig maximum operating pressure for high-pressure system applications
• Rated to 1000 degrees F operating temperature, suitable for steam and high-heat service
• NPTF thread form on both connections for pressure-tight, thread-interference sealing
• Compact 2.66 inch overall length minimizes footprint in tight installations
• Part of the SS5405 Series MNPT to FNPT Expander line from Midland Industries

Compatibility

Designed as an OEM-style threaded adapter for 2-inch NPTF piping systems requiring a male-to-female expander configuration in stainless steel service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including the IPC and ASME B31 piping standards where required. Shut off and depressurize the system completely before removing or installing any threaded fittings. Use appropriate thread sealant or PTFE tape only if the application requires it, noting that NPTF threads are designed to seal on thread interference alone in many services. Do not overtighten, as excessive torque on stainless steel threads can cause galling.
