B K Mueller 587-001HN Black Close Nipple 1.5 in

Product Description

The B K Mueller Industries 587-001HN is a black close nipple designed for threaded pipe assemblies in residential and light commercial plumbing and gas distribution systems. A close nipple has no exposed center unthreaded section, making it ideal for connecting two female-threaded fittings as close together as possible. At 1.5 inches nominal pipe size, this nipple fits standard NPT threaded applications and is commonly used where a tight, compact connection is required. Licensed plumbers and pipefitters install this type of fitting in gas lines, steam systems, and black iron piping assemblies. The black finish indicates plain carbon steel construction without galvanizing, appropriate for natural gas and propane distribution in accordance with IFGC guidelines.

This close nipple is suited for residential and commercial gas piping, steam distribution, and black iron pipe systems. The 1.5-inch size is a common dimension in branch line and riser applications. It ships in a package quantity of 5, making it practical for service vans and shop stock where multiple nipples are needed for a single job or across multiple service calls.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local codes and the International Fuel Gas Code (IFGC) where applicable. Shut off the gas supply or system pressure and verify zero pressure before threading or unthreading any fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium before assembly. Do not use galvanized fittings or dissimilar metals in the same gas line assembly without verified code compliance.
