Mueller Streamline 586-000r Black Steel Close Nipple

Product Description

The MUELLER STREAMLINE 586-000r is a black steel close nipple designed for threaded pipe assemblies in plumbing, OEM, oil, gas, and steam applications. Manufactured to ASTM A733/A53 material specification with a Schedule 40 standard wall thickness, this close nipple features male threaded connections on both ends conforming to ANSI/ASME B1.20.1 thread standards. The welded steel construction with a black finish delivers durability and resistance to rust and corrosion in demanding service environments. Each fitting is 100 percent inspected and quality tested before leaving the facility, making it a reliable choice for licensed plumbers and pipefitters working in both residential and commercial settings.

This close nipple is sized at 1-1/4 inches with an overall length of 1-5/8 inches, making it suitable for tight-clearance installations where minimal pipe extension between two fittings or valves is required. It is appropriate for use in plumbing systems, OEM fabrication, oil distribution lines, gas piping, and steam systems where Schedule 40 black steel pipe and fittings are specified. The NAFTA-compliant sourcing meets domestic content requirements for applicable projects.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code, and the International Fuel Gas Code where gas service is involved. Shut off and depressurize the system completely before removing or installing any threaded pipe components. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly, and tighten connections using properly sized pipe wrenches. Do not over-torque threaded joints on steel nipples, as this can damage threads or adjacent fittings.
