B K/mueller Inds(import) 563-001HN Galvanized Close Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 563-001HN is a 1/2 inch close galvanized steel nipple used in threaded pipe assemblies across plumbing, HVAC, and light industrial applications. A close nipple has threads running nearly the full length of the body with minimal unthreaded center, allowing two fittings to be joined with almost no gap between them. The hot-dip galvanized coating provides corrosion resistance suited for water supply, gas distribution, and general fluid handling systems. This part ships in a package quantity of 20 units, making it a practical stocking item for service trucks and job-site supply.

Close nipples in this size see routine use in residential and light commercial plumbing rough-in work, gas piping assemblies, fire suppression system risers, and HVAC water-side piping. The 1/2 inch nominal pipe size is one of the most common thread sizes in threaded black and galvanized iron systems. Licensed plumbers, pipefitters, and HVAC mechanics install these as part of threaded pipe trains where back-to-back fittings are required or where a standard length nipple would create unwanted offset.

Key Features

• Close configuration allows two fittings to thread together with minimal spacing between them
• Galvanized finish provides corrosion resistance for water supply and general fluid service
• 1/2 inch nominal pipe size with standard NPT threading on both ends
• Sold in a package quantity of 20 units for efficient stocking
• Lightweight at approximately 1.18 pounds per package of 20

Compatibility

Designed as an OEM-style replacement and standard-stock fitting compatible with 1/2 inch NPT threaded pipe systems using galvanized or black iron fittings in plumbing and piping assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for threaded pipe joints. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and use a proper pipe wrench or strap wrench to tighten without over-torquing the fitting. Shut off the water supply or gas service and depressurize the line fully before removing or replacing any threaded nipple in an existing system. Inspect threads for damage before installation to ensure a leak-free joint.
