Midland Industries 49204 Pipe Nipple 3in Mpt Sch 40 316 Ss

Product Description

The MIDLAND INDUSTRIES 49204 is a Schedule 40 welded pipe nipple machined from 316 stainless steel for demanding fluid and gas piping applications. It measures 4.5 inches in length with a 3-inch diameter and carries male pipe thread (MPT) connections on both ends conforming to ANSI B1.20.1 dimensional standards. Rated to 150 psi, this nipple is suited for systems where corrosion resistance and pressure integrity matter. Its 316 stainless steel construction resists chloride-bearing environments, making it a reliable choice in chemical, marine, and industrial process lines as well as commercial plumbing systems.

This nipple is used in commercial and industrial piping systems requiring a short, rigid connection between two female-threaded fittings, valves, or equipment ports. The 3-inch MPT thread on both ends allows it to thread directly into flanges, unions, or tee fittings without additional adapters. It is commonly specified on process lines, pump discharge headers, and mechanical room manifolds where stainless steel construction is required by code or system design. Licensed plumbers and pipefitters are the primary installers in both new construction and retrofit applications.

Key Features

• 316 stainless steel construction resists corrosion in harsh and chloride-exposed environments
• Schedule 40 wall thickness rated to 150 psi working pressure
• 3-inch MPT on both ends conforming to ANSI B1.20.1 thread standards
• 4.5-inch overall length for close-coupled fitting connections
• Welded construction for consistent dimensional integrity

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 stainless steel piping systems with 3-inch female-threaded (FPT) connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or ASME B31 piping codes. Isolate and depressurize the system completely before removing any existing fitting or threading in this nipple. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before assembly. Do not over-torque the connection, as stainless steel threads are susceptible to galling.
