The ASC Engineered Solutions 831011408 is a galvanized steel pipe nipple used to connect threaded pipe sections in plumbing, HVAC, and general piping systems. Measuring 3/8 inch in diameter by 5-1/2 inches in length, this close-tolerance nipple provides a rigid, corrosion-resistant threaded joint suitable for water, gas, and air service lines. The hot-dipped galvanized finish protects against rust in both exposed and semi-exposed installations. Licensed plumbers and pipefitters are the typical installers, though HVAC and mechanical contractors also use nipples of this size for connecting auxiliary lines and condensate or supply piping.
This nipple is well suited for residential and light commercial piping work where a short, fixed-length threaded connector is required. It is commonly used in supply and distribution lines, risers, and lateral connections in tight spaces where a longer run is not needed. The 3/8 inch size is frequently found in gas branch lines, water supply drops, and compressed-air distribution setups in mechanical rooms and utility installations.
Designed as a standard NPT threaded pipe nipple for use with 3/8 inch threaded pipe fittings in residential and commercial plumbing, gas, and mechanical piping systems.
This nipple is installed by licensed plumbers, pipefitters, or qualified HVAC-R technicians using pipe wrenches and appropriate thread sealant or tape rated for the intended service. Shut off and depressurize the line before removing or installing any threaded pipe component. Follow local plumbing and mechanical codes, including applicable IPC and IFGC requirements, for pipe joining materials and methods. Do not overtighten threaded connections, as this can crack fittings or distort threads.
