Bk Mueller 568-045HC Galvanized Pipe Nipple 2 in Sch 40

Product Description

The BK MUELLER 568-045HC is a galvanized steel pipe nipple designed for threaded pipe assemblies in plumbing, mechanical, and industrial piping systems. Manufactured to Schedule 40 wall thickness standards, this nipple measures 2 inches in diameter and 4.5 inches in length, with NPT threads on both ends. The hot-dip galvanized coating provides corrosion resistance in wet or exposed environments. Licensed plumbers and pipefitters install this type of fitting to connect sections of threaded pipe, extend runs, or adapt between fittings in water supply, gas distribution, and general-purpose piping systems. At 2.5 pounds, the fitting reflects the solid steel construction expected of Schedule 40 components.

This nipple is suited for residential and light commercial plumbing installations, mechanical rooms, industrial process piping, and retrofit or repair work on existing galvanized systems. The 2-inch pipe size and 4.5-inch length make it a common choice for short offset runs and close-quarter connections where a longer nipple is not practical. Both ends are threaded to standard NPT dimensions, allowing direct assembly with standard threaded couplings, tees, elbows, and valves without additional preparation.

Key Features

• Schedule 40 wall thickness for standard-pressure plumbing and mechanical applications
• Galvanized steel construction resists corrosion in wet and exposed environments
• NPT threads on both ends for compatibility with standard threaded pipe fittings
• 2-inch pipe size suits common residential and commercial main-line connections
• 4.5-inch length provides a short extension between fittings without excessive pipe run

Compatibility

Designed as an OEM-style replacement or standard component for Schedule 40 threaded galvanized piping systems using 2-inch NPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the water or gas supply and relieve system pressure before removing or installing threaded nipples. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus wrench-tight per standard practice. Verify local code requirements under the IPC or IFGC before installing galvanized fittings on gas lines, as approved materials vary by jurisdiction.
