Midland Industries 57332TV Pipe Nipple 4in Threaded Grooved Sch 40

Product Description

The MIDLAND INDUSTRIES 57332TV is a seamless black steel pipe nipple designed for piping systems that transition between threaded and grooved connections. Rated at Schedule 40 wall thickness, this nipple measures 10 inches in length with a 4-inch diameter on both ends. One end features NPT threads conforming to ANSI B1.20.1 dimensional standards, while the other end is grooved for use with mechanical groove-style couplings. Rated for service from -200 degrees F to 150 degrees F, it is suited for demanding fluid and gas distribution applications. Plumbers, pipefitters, and mechanical contractors install this fitting in both new construction and retrofit piping assemblies.

This nipple is commonly used in commercial and industrial piping systems where a threaded pipe section must connect to a grooved mechanical coupling system. Typical applications include fire suppression supply lines, hydronic heating and cooling distribution, and general black iron piping runs. The thread-by-groove configuration is frequently specified when transitioning between legacy threaded infrastructure and modern grooved piping components without additional adapters.

Key Features

• Seamless steel construction provides consistent wall integrity throughout the nipple body
• Schedule 40 wall rating suitable for standard pressure service in black iron piping systems
• One NPT threaded end conforming to ANSI B1.20.1 for reliable leak-free thread engagement
• One grooved end compatible with standard mechanical groove couplings
• Black finish appropriate for non-potable fluid, hydronic, and gas distribution service
• Temperature range of -200 degrees F to 150 degrees F supports a wide range of system conditions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 black steel piping systems using 4-inch threaded and grooved connections conforming to ANSI B1.20.1 thread standards.

Installation Notes

Installation should be performed by a licensed plumber or certified pipefitter in accordance with applicable local mechanical and plumbing codes, including IPC and IFGC where relevant. Depressurize and isolate the piping system completely before removing or installing any fitting. Apply appropriate thread sealant or tape to the NPT end before make-up, and ensure the grooved end groove profile is undamaged and compatible with the mechanical coupling being used. Do not use this fitting beyond its rated temperature or pressure specifications.
