The ANVIL 0330501602 is a black steel pipe nipple designed for use in threaded piping systems requiring a compact, high-pressure-rated connection. Built to Schedule 80 wall thickness and seamless construction, this nipple delivers greater pressure capacity than standard Schedule 40 fittings. At 1/8 inch nominal diameter and 4-1/2 inches in length, it is well suited for tight-clearance runs in gas, steam, or water distribution systems. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians frequently use small-diameter nipples like this in gas supply and condensate piping work. Threaded ends conform to ASME B1.20.1 for consistent, leak-free makeup with standard NPT fittings.
This nipple is commonly installed in residential and light commercial systems where a short, rigid threaded connection is needed between valves, tees, elbows, or equipment inlets. The 1/8 inch diameter is typical in low-flow gas pilot lines, instrument ports, pressure tap connections, and small steam or water service lines. The black finish is standard for gas service applications per common code practice, and the seamless body eliminates the weld seam as a potential failure point under cyclic pressure or thermal stress.
Designed as an OEM-style replacement or new-installation fitting for threaded 1/8 inch NPT piping systems in gas, steam, and water service applications.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and isolate the supply line and depressurize the system before removing or installing any threaded fitting. Apply an appropriate thread sealant or tape rated for the service fluid before makeup. Do not over-tighten threaded connections, as this can crack fittings or damage threads on mating components.
