The VALUE COLLECTION 590-040XSBC is a Schedule 80 seamless black pipe nipple used in industrial and commercial piping systems. With a nominal pipe size of 3 inches and a length of 4 inches, this nipple is suited for connecting threaded pipe sections where higher wall thickness and added pressure tolerance are required. Schedule 80 construction provides a thicker wall than Schedule 40, making it appropriate for demanding service conditions. Licensed plumbers and pipefitters install this type of fitting during new construction, retrofits, and system expansions.
This black pipe nipple is used in steam, gas, and liquid piping applications common to mechanical rooms, commercial HVAC systems, and industrial process lines. Its seamless construction reduces the risk of weak points along the body, which is important in higher-pressure or higher-temperature services. The 3-inch diameter fits standard NPT threaded pipe and fittings of the same nominal size, making it a direct drop-in for maintenance and repair work.
Designed as an OEM-style replacement or stock fitting for threaded Schedule 80 black iron piping systems using 3-inch nominal pipe size.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before making up the joint. Do not use this fitting in potable water service without confirming material suitability under local code.
