Mueller Industries 586-180 Threaded Black Pipe 1-1/4in 18in

Product Description

The MUELLER INDUSTRIES 586-180 is a pre-cut, threaded black oxide carbon steel pipe designed for use in plumbing, mechanical, and gas distribution systems where ready-to-install pipe sections save labor and reduce on-site cutting time. Manufactured to ASTM A-53 specification with a welded construction, this pipe meets ANSI B1.20.1 thread standards. It carries a standard (STD) schedule rating suitable for a wide range of pressure applications. Thread protectors on each end guard against handling damage during transport and staging, keeping threads clean and ready for connection on arrival at the job site.

This pipe is suited for residential and light commercial installations involving gas lines, water distribution, and mechanical piping systems where black steel pipe is code-required or preferred. The 18-inch pre-cut length works well as a nipple or short run segment in tight mechanical spaces or for completing final connections at equipment. Licensed plumbers and pipefitters typically install this material. The 1-1/4-inch nominal size fits common supply and distribution configurations in both new construction and retrofit work.

Key Features

• Pre-cut to 18 inches for ready installation without additional cutting or threading

• ASTM A-53 carbon steel construction for pressure-rated service
• Black oxide finish suited for gas and non-potable water applications

• Welded manufacturing method with STD schedule wall thickness

Compatibility

Designed as an OEM-style replacement or standard supply pipe for residential and commercial black steel piping systems using 1-1/4-inch threaded fittings and couplings.

Installation Notes

Installation of black steel threaded pipe should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the application. Shut off gas or water supply and depressurize the line before making any connections. Use an appropriate thread sealant or listed pipe tape rated for the service fluid. Inspect threads on both pipe ends before installation and remove thread protectors immediately prior to use.
