Description
The B K Mueller Industries 564-045HN is a galvanized steel pipe nipple used in threaded piping systems across plumbing, HVAC, and light industrial applications. Measuring 0.75 inches in diameter and 4.5 inches in length, this close-cut nipple provides a rigid, corrosion-resistant connection between threaded fittings, valves, and pipe assemblies. The hot-dip galvanized finish protects against rust and oxidation, making it suitable for both interior and exterior installations. Sold in a package of 10, this nipple is a standard restocking item for service trucks and shop inventory.
This nipple is used in residential and commercial plumbing rough-in, gas distribution piping (where local codes permit galvanized fittings), HVAC condensate and supply line assemblies, and general utility piping. It threads directly into standard NPT fittings and is well suited for bracketed runs, manifold connections, and short offset installations where a rigid nipple is required.
Key Features
- Galvanized steel construction provides corrosion resistance for wet and outdoor environments
- 0.75-inch NPT threaded ends mate with standard fittings, valves, and couplings
- 4.5-inch length suits short offset and close-clearance piping runs
- Packaged in quantities of 10 for efficient restocking and bulk service work
- Compatible with standard pipe wrenches and threading tools for fast installation
Compatibility
Designed as a standard OEM-style replacement and new-installation nipple for 0.75-inch NPT threaded piping systems in plumbing and mechanical applications.
Installation Notes
Installation is performed by licensed plumbers or qualified mechanical contractors. Shut off the water supply or gas source and relieve system pressure before making any threaded connections. Apply an appropriate thread sealant or PTFE tape to all male NPT threads before assembly. Verify local code compliance, particularly for galvanized fittings in gas service applications, as requirements vary by jurisdiction under the IFGC and local amendments.
