Mueller Streamline 583-000p66 Black Steel Nipple Assortment

Product Description

The MUELLER STREAMLINE 583-000p66 is a 66-piece black carbon steel nipple assortment covering close nipples through 6-inch lengths in a 1/2-inch pipe size. Each nipple is manufactured to ASTM A53 Grade A standards using a welded construction method and finished with a standard black coating. Rated to 1879 psi, the assortment suits high-demand gas, air, and liquid piping systems where a range of close-quarter to longer reach fittings are needed on a single job. Licensed plumbers and pipefitters turn to this type of kit to minimize trips to the supply house when fitting out mechanical rooms, boiler systems, or gas distribution headers.

This assortment is suited for residential and light commercial plumbing and gas piping applications. The 1/2-inch MIPT threaded ends connect directly to standard pipe fittings, valves, and manifolds. Having nipples ranging from close through 6 inches in one package allows a technician to dial in exact offset distances during rough-in or service work without cutting and threading pipe on site. The black finish is standard for gas line service in many jurisdictions.

Installation Notes

Installation 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 relevant to the service. Shut off and isolate the gas or fluid supply and verify zero pressure before making or breaking any threaded connections. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all MIPT connections. Do not over-tighten threaded nipples into cast fittings, as this can crack the fitting body.
