Asc 8700149357 Galvanized Pipe Nipple 1/2 X 4 in Sch 40

Product Description

The ASC Engineered Solutions 8700149357 is a welded steel galvanized pipe nipple used to make threaded pipe connections in plumbing, mechanical, and gas piping systems. Sized at 1/2 inch nominal diameter by 4 inches in length, it is manufactured to Schedule 40 wall thickness and hot-dip galvanized to resist corrosion. The nipple meets ASTM A53 standards and is manufactured with no more than 0.25% weighted average lead content on wetted surfaces, making it suitable for potable water applications where lead-content compliance is required. Licensed plumbers and pipefitters are the primary installers of this type of fitting in both residential and light commercial work.

This nipple is suited for use in residential and commercial plumbing systems, hydronic heating distribution lines, fire protection rough-in, and low-pressure gas piping where threaded galvanized steel is the specified material. The 1/2 inch by 4 inch size is commonly used in branch connections, riser stubs, and close-quarters transitions between fittings or valves. It threads directly into standard NPT-compatible couplings, tees, elbows, and valves without modification.

Key Features

• Hot-dip galvanized finish provides corrosion resistance for wet and outdoor environments
• Schedule 40 wall thickness meets standard pressure ratings for typical plumbing and mechanical applications
• Meets ASTM A53 standard for welded steel pipe
• Lead content limited to 0.25% weighted average on wetted surfaces for potable water compliance
• Standard NPT threads on both ends for compatibility with threaded fittings and valves

Compatibility

Designed as an OEM-style replacement or standard stock nipple for use in threaded Schedule 40 galvanized steel piping systems with NPT-compatible fittings, valves, and couplings.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape rated for the intended service. Always depressurize and drain the system before removing or installing threaded nipples. Follow applicable local plumbing codes and IFGC requirements for gas piping applications. Do not overtighten threaded connections, as this can crack fittings or distort threads.
