B K/mueller 565-045HC Galvanized Pipe Nipple 1x4.5 in

Product Description

The B K/Mueller Industries 565-045HC is a galvanized steel pipe nipple sized at 1 inch nominal diameter by 4.5 inches in length. Pipe nipples serve as short threaded connectors used to join sections of pipe, fittings, or valves within a piping assembly. The galvanized zinc coating provides corrosion resistance suited to water supply, general plumbing, and light industrial applications. Licensed plumbers and pipefitters install these nipples as part of threaded iron pipe systems in both above-ground and some below-grade configurations. The 565-045HC ships in a package quantity of 10 units.

This nipple is suited for residential and light commercial plumbing and mechanical systems where threaded galvanized iron pipe is specified. Common applications include domestic water distribution, gas distribution lines where local codes permit galvanized fittings, heating system supply and return lines, and general maintenance or repair work on existing galvanized piping systems. Its standard 1 inch NPT threading makes it compatible with the broad range of threaded iron pipe fittings and valves available in the trade.

Key Features

• Galvanized zinc coating provides corrosion resistance for water and mechanical piping applications
• Standard 1 inch NPT threads on both ends for compatibility with threaded iron pipe fittings
• 4.5 inch length suits close-quarter connections where longer run nipples are not required
• Sold in a package quantity of 10, suitable for service truck stocking or job-lot use
• Each unit sold individually (unit of measure: EA) within the 10-pack configuration

Compatibility

Designed as a standard 1 inch NPT threaded galvanized pipe nipple for use with conventional threaded iron pipe systems and fittings conforming to ANSI pipe thread standards.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded iron pipe systems. Shut off and depressurize the line before removing or installing any threaded pipe components. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly. Tighten fittings with a pipe wrench to proper engagement — avoid over-tightening, which can crack cast fittings or distort threads. Verify local code requirements for use of galvanized pipe in potable water or gas service before installation.
