Anvil 0332810407 Black Pipe Nipple 1/2 in Schedule 160

Product Description

The ANVIL 0332810407 is a black steel pipe nipple designed for high-pressure threaded piping systems. At 1/2 inch nominal pipe size and 2-1/2 inches in length, it serves as a close-coupled connector between threaded fittings, valves, and equipment. The Schedule 160 wall thickness makes it suitable for demanding service conditions where standard Schedule 40 or 80 material is not rated for the application. Licensed plumbers and pipefitters install this nipple in gas, steam, and hydraulic piping runs where heavy-wall, black-finish steel is specified by code or engineering design.

This nipple is used in commercial and industrial piping installations where Schedule 160 wall thickness is required for elevated pressure or mechanical load applications. Typical scenarios include connections at boilers, compressors, and high-pressure distribution headers. The black finish indicates the absence of galvanizing, which is standard practice for natural gas and steam service piping in many jurisdictions. It is also used in residential and light commercial plumbing where heavy-wall steel is called out on the plans.

Key Features

• Schedule 160 wall thickness for high-pressure service applications
• 1/2 inch nominal pipe size with NPT threads on both ends
• 2-1/2 inch overall length for short-run connections between fittings or equipment
• Black finish suitable for gas, steam, and non-galvanized piping systems
• Threaded ends for tool-only installation with no welding required

Compatibility

Designed as an OEM-style replacement or standard-stock component for 1/2 inch NPT threaded Schedule 160 black steel piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable code requirements such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the piping system completely before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up threads. Do not over-tighten threaded connections, as Schedule 160 fittings and mating components can crack if excessive force is applied without proper support.
