Asc 8700159752 Malleable Iron Galvanized Plug 1/4 in

Product Description

The ASC Engineered Solutions 8700159752 is a 1/4 inch malleable iron galvanized plug designed to seal threaded pipe openings in piping systems. The hollow core design is standard for regular-pattern plugs and keeps weight low while maintaining structural integrity. This fitting is galvanized for corrosion resistance and conforms to Federal Specification WW-P-471-B, ANSI B-16.14 for dimensions, and ANSI B-2.1 for pipe threads. Licensed plumbers and pipefitters install this type of plug when capping off unused tapped openings in distribution lines, manifolds, and fittings across a wide range of piping applications.

This plug is suited for residential and light commercial plumbing, HVAC hydronic systems, and general pipe fitting applications where a 1/4 inch NPT threaded closure is required. The galvanized finish makes it appropriate for systems exposed to moisture or moderate corrosive conditions. It is sold individually and is commonly used alongside malleable iron fittings in pressure piping assemblies that require sealed ports or testing caps.

Key Features

• Hollow core regular plug design for standard threaded pipe closures
• Galvanized malleable iron construction for corrosion resistance
• Meets Federal Specification WW-P-471-B
• Conforms to ANSI B-16.14 dimensional standards and ANSI B-2.1 pipe thread specifications
• 1/4 inch NPT thread size for compatibility with standard pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch NPT threaded ports in malleable iron piping assemblies, consistent with Class 150 malleable iron fitting systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable local plumbing codes and IFGC or IPC guidelines where relevant. Shut off system pressure and drain the line before installing or removing any threaded plug. Apply pipe thread sealant or PTFE tape to the male threads before seating the plug, and tighten with an appropriate pipe wrench. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
