Nipples 330001801 Black Steel Pipe Nipple 1/8 X 4.5 in Npt

Product Description

The NIPPLES 330001801 is a domestic black steel pipe nipple conforming to ASTM A733 dimensional standards and ASTM A53 welded steel pipe material requirements. Threads are cut to NPT per ASME B1.20.1 for reliable, leak-resistant connections in pressure piping systems. Sized at 1/8 inch nominal diameter by 4-1/2 inches in length, this nipple is suited for joining threaded pipe sections in gas, water, and general-purpose plumbing and mechanical systems. Licensed plumbers, pipefitters, and HVAC mechanics routinely install this type of fitting in both new construction and retrofit applications.

This nipple is appropriate for residential and light commercial piping installations where a short close extension or offset is needed between threaded fittings or valves. Typical applications include gas supply lines, compressed air distribution, water distribution headers, and general mechanical piping. The black steel finish is standard for gas service in many jurisdictions. Figure No. 339 classification identifies the fitting within the Beck nipple product line.

Key Features

• ASTM A53 welded steel pipe construction for consistent wall integrity
• NPT threads per ASME B1.20.1 ensure compatibility with standard threaded fittings
• ASTM A733 dimensional compliance for predictable fit in threaded assemblies
• Black steel finish standard for gas piping applications per most local codes
• Figure No. 339 designation for straightforward ordering and replacement

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with 1/8 inch NPT threaded pipe systems. Standard and Extra Heavy Right and Left Nipples are available in 1/8 inch through 4 inch diameter in 4 inch or 6 inch lengths within this product family.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including the IPC and IFGC where applicable. Shut off gas or water supply and depressurize the line before disassembly or fitting installation. Apply thread sealant or PTFE tape appropriate for the service medium before makeup. Do not use excessive force on 1/8 inch diameter fittings, as over-torquing small-diameter NPT threads can damage threads or fittings.
