Midland Industries 49112 Pipe Nipple 1 in Mpt 9 in Sch 40 316 Ss

Product Description

The MIDLAND INDUSTRIES 49112 is a welded pipe nipple machined from 316 stainless steel for use in plumbing, industrial piping, and fluid-handling systems where corrosion resistance is critical. This nipple measures 9 inches in length with a 1-inch diameter and carries a Schedule 40 wall rating. Both ends are threaded male pipe thread (MPT) conforming to ANSI B1.20.1 with a 1-11-1/2 thread form. It is rated to 150 psi and suited for installation by licensed plumbers or pipefitters working on potable water, chemical, or marine applications.

This nipple is appropriate for residential and commercial piping systems where standard carbon steel or brass fittings would be prone to corrosion. Typical installations include coastal environments, chemical processing lines, food-service plumbing, and pool or spa mechanical rooms. The 316 stainless steel alloy offers superior chloride and oxidation resistance compared to 304 stainless. It threads directly into standard 1-inch female NPT fittings, valves, manifolds, and equipment ports without adapters.

Key Features

• 316 stainless steel construction resists corrosion in chloride-rich and chemical environments
• Schedule 40 wall thickness rated to 150 psi working pressure
• Both ends threaded 1-11-1/2 MPT conforming to ANSI B1.20.1
• 9-inch length suits a range of close and extended-reach piping configurations
• Welded construction provides consistent thread engagement and structural integrity

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-inch female NPT valves, couplings, tees, and equipment ports in Schedule 40 piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the water supply and relieve system pressure before removing or installing pipe nipples. Apply a thread sealant or PTFE tape to the male threads in accordance with IPC and local plumbing code requirements. Do not over-torque threaded connections, as stainless steel threads are susceptible to galling without proper lubrication or anti-seize compound.
