Sigma D.NME Malleable Iron Extension Piece 1/2 in Nps 150 Lb

Product Description

The SIGMA D.NME is a galvanized malleable iron extension piece designed for use in threaded pipe assemblies. It features a 1/2 inch nominal size with NPS end style threading and is rated at 150 lb. Extension pieces are used to extend the reach of a pipe run or to reposition a fitting outlet without adding a full pipe length. This fitting is manufactured domestically and is installed by licensed plumbers and pipefitters working on gas, water, or steam distribution systems.

This fitting is suited for residential and light commercial plumbing and gas piping applications where a 1/2 inch NPS threaded connection is required. The galvanized finish provides corrosion resistance, making it appropriate for exposed or damp environments. Its 150 lb pressure class covers the demands of standard service lines in low-pressure systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Always shut off and depressurize the supply line before disassembling or adding fittings. Apply an appropriate thread sealant or PTFE tape to all threaded connections before assembly. Do not overtighten threaded fittings, as malleable iron threads can be damaged by excessive force.
