Nipples 330017203 Black Steel Pipe Nipple 1/2 X 8 in

Product Description

The NIPPLES 330017203 is a black steel pipe nipple sized at 1/2 inch diameter by 8 inches in length, manufactured from ASTM A53 welded steel pipe. It is threaded on both ends with NPT threads conforming to ASME B1.20.1, allowing secure connection to standard pipe fittings, valves, and couplings. Dimensioned to ASTM A733 standards under Figure No. 339, this nipple is built for reliable performance in gas, water, and general-purpose piping systems. Licensed plumbers and pipefitters install this type of fitting in both new construction and service work across residential and light commercial applications.

This nipple is suited for use in plumbing, HVAC, gas distribution, and industrial piping systems where a short close-coupled connection is required between two threaded components. The 1/2 inch by 8 inch size fits common branch lines and service connections. The black steel finish makes it a standard choice for gas piping systems. It is available as part of a broader range of nipples covering 1/8 inch through 4 inch diameters in standard and extra heavy schedules, with right and left thread options also available.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape rated for the intended service. Shut off gas or water supply and depressurize the line before removing or installing any threaded pipe fitting. Follow applicable local plumbing codes and IFGC requirements when using in gas service. Do not overtighten threaded connections, as this can damage threads and cause leaks.
