B K/mueller 564-035HN Galvanized Pipe Nipple 3/4x3-1/2

Product Description

The B K/Mueller Industries 564-035HN is a galvanized steel pipe nipple measuring 3/4 inch in diameter by 3-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other threaded components in a piping system. This nipple features a hot-dip or mill galvanized zinc coating that provides corrosion resistance in wet and outdoor environments. It is a standard close-to-short nipple used by plumbers, pipefitters, and HVAC mechanics in both new construction and retrofit applications. Sold in a package quantity of 15 pieces.

This galvanized nipple is suited for residential and light commercial plumbing, gas distribution, and HVAC piping systems where a threaded steel connection is required. Typical applications include connecting shut-off valves, unions, elbows, and tees in water supply, compressed air, and low-pressure gas lines. The galvanized finish makes it appropriate for exposed or semi-exposed installations where bare black iron would corrode prematurely.

Key Features

• 3/4 inch nominal pipe size with 3-1/2 inch overall length
• Galvanized zinc coating for corrosion resistance in wet and outdoor conditions
• Male NPT threads on both ends for standard threaded connections
• Steel construction for durability under pressure
• Packaged in quantities of 15 for jobsite efficiency

Compatibility

Designed as a standard NPT-threaded galvanized pipe nipple for use with 3/4 inch threaded fittings, valves, and pipe in residential and commercial plumbing and HVAC piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the intended service. Apply thread sealant tape or pipe dope rated for the service type to all NPT threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or distort threads. Always shut off and depressurize the system before making or breaking any threaded connection.
