Mueller Streamline 585-000r 1 Inch Black Steel Close Nipple

Product Description

The MUELLER STREAMLINE 585-000r is a black steel close nipple designed for threaded pipe connections in plumbing, OEM fabrication, oil, gas, and steam service applications. Manufactured to ASTM A733/A53 specifications and conforming to ANSI/ASME B1.20.1 thread standards, this Schedule 40 standard-wall nipple features male threaded connections on both ends. The welded steel construction and black finish provide solid durability across a range of industrial and mechanical piping systems. Each nipple is 100 percent inspected and quality tested before leaving the facility. This fitting is sized at 1 inch nominal with a close pattern and an overall length of 1.5 inches.

This close nipple is suited for residential and commercial piping installations where a minimal-length threaded connection between two fittings or valves is required. Common applications include gas distribution piping, steam lines, plumbing rough-in, and OEM equipment assembly. The black steel construction makes it appropriate for gas and steam service where galvanized fittings are not permitted. Licensed plumbers, pipefitters, and mechanical contractors routinely use close nipples of this type when building threaded piping assemblies.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off the gas supply or isolate the piping system and relieve pressure before beginning work. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before making up the threaded connection. Do not over-tighten threaded fittings, as this can crack adjacent fittings or distort the threads.
