B K/mueller Inds(import) 585-001HN Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 585-001HN is a 1-inch close-pattern black pipe nipple designed for threaded pipe assemblies in gas, air, and water distribution systems. A close nipple has no exposed unthreaded center — the threads run end to end — making it the right choice when fittings or valves need to be positioned as close together as possible. These nipples are sold in a package of 10 and are typically installed by plumbers, pipefitters, and HVAC technicians working on low-pressure black iron piping runs.

Close nipples in this size are commonly used in residential and light commercial gas-line distribution, steam heating systems, compressed-air lines, and general industrial piping. The 1-inch nominal size fits standard NPT threaded fittings, valves, unions, and tees of the same size. This package quantity of 10 suits service vans and shop stock for contractors who replace nipples frequently during system repairs or new installations.

Key Features

• Close-pattern threading — no exposed center, maximum fitting-to-fitting proximity
• 1-inch nominal NPT thread size, compatible with standard threaded fittings
• Black iron finish suitable for gas, air, and non-potable water service
• Packaged in quantities of 10 for stocking and service efficiency
• Each unit sold as a single count (EA) within the 10-piece pack

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 1-inch NPT threaded black iron piping systems.

Installation Notes

Close nipples are installed by licensed plumbers or pipefitters in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service type. Shut off and depressurize the piping system completely before removing or installing any threaded components. Apply an appropriate thread sealant or PTFE tape rated for the intended service — confirm compatibility with gas service before use. Because close nipples have no exposed unthreaded center, use strap wrenches or jaw-protected pipe wrenches to avoid damaging the threads during installation.
