Anvil 0332850841 Black Steel Pipe Nipple 4 in Sch 160

Product Description

The ANVIL 0332850841 is a black steel threaded pipe nipple designed for high-pressure piping systems where heavier wall thickness is required. Measuring 4 inches in diameter and 8 inches in length, this Schedule 160 nipple provides significantly greater wall thickness than standard Schedule 40 or 80 fittings, making it appropriate for demanding industrial, mechanical, and commercial piping applications. The black finish coating is standard for non-galvanized steel pipe used in gas, steam, and hydronic systems. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of Schedule 160 nipples in code-regulated piping systems.

This nipple is suited for high-pressure or high-temperature piping systems where Schedule 40 or Schedule 80 wall thickness is insufficient. Typical applications include industrial process piping, steam distribution, hydraulic systems, and commercial mechanical rooms. The 4-inch diameter and 8-inch length make it a close nipple extension for connecting valves, flanges, fittings, or equipment in large-bore piping assemblies. Both ends are threaded per NPT standards, allowing direct engagement with standard threaded fittings and components.

Key Features

• Schedule 160 wall thickness for high-pressure piping service
• 4 inch nominal pipe diameter with NPT threaded ends
• 8 inch overall length suits close-coupled valve and fitting installations
• Black finish coating standard for non-galvanized steel piping systems
• Compatible with standard NPT threaded fittings, couplings, and valves

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 160 black steel threaded piping systems using 4 inch nominal pipe size fittings and valves.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the piping section completely before removing or installing any threaded nipple. Apply a listed pipe thread sealant or PTFE tape to the male threads before engagement. Do not over-tighten threaded connections, as this can damage the threads or fittings.
