Midland Industries SS5405-12-12 Pipe Adapter 3/4 in Nptf 316 Ss

Product Description

The MIDLAND INDUSTRIES SS5405-12-12 is a 316 stainless steel pipe adapter in the SS5405 Series, designed to connect a 3/4-inch male NPTF thread to a 3/4-inch female NPTF thread. With a maximum operating pressure of 4600 psi and a rated operating temperature of 1000 degrees F, this adapter is built for demanding fluid and gas piping applications where corrosion resistance and high-pressure integrity are critical. The 3/4-14 thread specification ensures a precise, leak-resistant fit. Licensed plumbers, pipefitters, and industrial technicians are the primary installers for this type of fitting.

This adapter is suited for residential, commercial, and industrial piping systems where stainless steel fittings are required to resist corrosion from aggressive media, high temperatures, or caustic environments. Common applications include steam lines, hydraulic systems, chemical transfer lines, and high-pressure water systems. The 316 stainless steel construction makes it appropriate for marine, food-service, and chemical processing environments where 304 SS would be insufficient. Its compact 1.929-inch length allows installation in tight piping assemblies without excessive clearance requirements.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and marine environments
• Maximum operating pressure of 4600 psi suitable for high-pressure hydraulic and gas applications
• Rated to 1000 degrees F for use in steam and high-temperature piping systems
• 3/4-14 NPTF thread form provides a pressure-tight, metal-to-metal seal without sealant tape in many applications
• Compact overall length of 1.929 inches for installation in confined piping runs
• Part of the SS5405 Series MNPT to FNPT expander line for consistent fitment with other series components

Compatibility

Designed as an OEM-style replacement or new-installation fitting for piping systems requiring a 3/4-inch male NPTF to 3/4-inch female NPTF stainless steel adapter connection rated for high-pressure and high-temperature service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes, including IPC and IFGC guidelines where relevant. Depressurize and isolate the piping system fully before removing or installing any threaded fitting. NPTF threads are designed for a pressure-tight metal-to-metal seal, but thread sealant or PTFE tape may still be applied per system requirements and local code. Avoid over-torquing, which can crack or distort stainless steel fittings and compromise the seal.
