B K/mueller Inds(import) 582-001HN Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 582-001HN is a close-pattern black pipe nipple in 3/8 inch diameter. A close nipple is threaded end-to-end with no unthreaded center, making it the shortest possible threaded connection for a given pipe size. This fitting is used to join two female-threaded fittings back-to-back with minimal spacing. It is made for standard threaded black iron pipe systems and is installed by licensed plumbers, pipefitters, and HVAC technicians working on gas distribution, compressed air, or similar low-pressure piping applications.

This close nipple is suited for residential and light commercial gas piping, compressed air lines, and other black iron pipe assemblies where a tight, compact threaded connection is required. The close pattern eliminates any exposed center pipe, making it ideal for tight quarters or valve manifold assemblies. It ships in a package quantity of 10, making it practical for service contractors stocking fittings for multiple jobs.

Key Features

• Close-pattern threading — no exposed center, maximum compactness
• 3/8 inch nominal pipe size for standard NPT threaded fittings
• Black iron finish suitable for gas and compressed air service
• Sold in package quantity of 10 per unit of measure

Compatibility

Designed as an OEM-style replacement fitting compatible with standard 3/8 inch NPT threaded black iron pipe systems.

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 appropriate. Shut off all gas or air supply and verify zero pressure before removing or installing any threaded fittings. Apply an appropriate thread sealant or pipe tape rated for the service medium to all male threads before assembly. Close nipples require two pipe wrenches for installation and removal due to the absence of an unthreaded center grip.
