Midland Industries SS5405-24-24 Pipe Expander 1-1/2 in Nptf

Product Description

The MIDLAND INDUSTRIES SS5405-24-24 is a stainless steel pipe expander fitting designed for high-pressure, high-temperature fluid and gas piping systems. Configured as a 1-1/2 inch Male NPTF to 1-1/2 inch Female NPTF adapter, it provides a threaded connection point in the SS5405 Series lineup. Constructed from 316 stainless steel, this fitting is rated to 5000 psig maximum operating pressure and withstands operating temperatures up to 1000 degrees F. At 2.53 inches in length, it is compact enough for tight installations. Plumbers, pipefitters, and industrial maintenance technicians specify this fitting where corrosion resistance, pressure integrity, and thermal durability are required in a threaded pipe assembly.

This fitting is suited for residential and commercial piping applications where NPTF threaded connections are required and system media demands corrosion-resistant materials. Typical installation scenarios include process piping, hydraulic lines, steam systems, chemical transfer lines, and high-pressure fluid distribution networks. The 316 stainless steel construction makes it appropriate for use in corrosive environments, marine applications, and food-grade or sanitary systems where carbon steel fittings are unsuitable. The thread spec of 1-1/2 - 11-1/2 on both connection ends follows standard NPTF engagement requirements.

Compatibility

Designed as an OEM-style threaded pipe fitting compatible with 1-1/2 inch NPTF piping systems requiring a Male NPTF to Female NPTF expander connection in 316 stainless steel.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local and national plumbing codes, including IPC guidelines for threaded pipe connections. Shut down and fully depressurize the piping system before removing or installing any threaded fittings. NPTF threads are designed for pressure-tight engagement without sealant, but consult the system requirements and manufacturer guidance to determine whether thread sealant or tape is appropriate for the specific media. Do not overtighten threaded connections, as this can cause thread galling on stainless steel fittings.
