Midland Industries 62465MS Reducing Coupling 4x2.5 in Npt Ss

Product Description

The MIDLAND INDUSTRIES 62465MS is a reducing coupling designed to connect two different pipe sizes within a threaded piping system. It features a 4-inch Female NPT inlet on one end and a 2-1/2-inch Female NPT outlet on the other, allowing for a direct in-line pipe size reduction without additional adapters. Constructed from 304 stainless steel, this fitting is suited for applications where corrosion resistance and durability are required. The 150 lb pressure class rating makes it appropriate for moderate-pressure service lines. Plumbers, pipefitters, and mechanical contractors are the primary installers of this type of fitting.

This reducing coupling is used in residential and commercial plumbing, process piping, and mechanical systems where a transition from 4-inch to 2-1/2-inch threaded pipe is needed. The 4-8 x 2-1/2-8 thread designation indicates the thread pitch on each end. Applications typically include water supply lines, industrial fluid transfer, and general-purpose piping in environments where stainless steel is specified for corrosion or sanitary requirements. It is part of the SP-114 Fittings line within the 304 stainless steel category.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the IPC. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not over-torque stainless steel fittings, as galling can occur; use proper tools and technique for stainless threaded connections.
