The MIDLAND INDUSTRIES 103477 is a 1-1/2 inch threaded pipe cap manufactured from 304L stainless steel for high-pressure piping applications. Rated at 3000 lb pressure class, this cap is designed to close off the end of a threaded pipe run in systems where corrosion resistance and pressure integrity are critical. The 1-1/2-11-1/2 NPT thread ensures a secure, leak-resistant connection. At 1.69 pounds, the forged-style fitting meets the demands of industrial and commercial piping installations. Plumbers, pipefitters, and mechanical contractors specify this class of fitting when stainless material is required by system design or code.
This cap is suited for use in commercial and industrial piping systems where 3000 lb class fittings are specified. Typical applications include process piping, chemical handling lines, steam systems, and any high-pressure installation requiring corrosion-resistant stainless steel closures. It is categorized under 1000 lb and above fittings in the 304 stainless section, making it appropriate for demanding pressure service beyond standard 150 lb or 300 lb fitting ratings.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch NPT threaded piping systems requiring 3000 lb class stainless steel closures.
This fitting is installed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before removing or installing any threaded cap. Apply appropriate thread sealant or PTFE tape to the male threads before engagement; do not over-apply sealant in a way that could contaminate the system interior. Tighten using a pipe wrench to proper engagement without cross-threading the stainless threads.
