Asc 8700162459 Malleable Iron Galvanized Lock Nut 3/8 in

Product Description

The ASC Engineered Solutions 8700162459 is a 3/8-inch malleable iron lock nut with a hot-dip galvanized finish, used to secure threaded pipe fittings and prevent loosening in piping assemblies. Manufactured to meet ASTM A-197 standards for chemical and physical properties and ASTM A-153 for galvanizing, this lock nut delivers reliable corrosion resistance in both exposed and concealed installations. Pipe threads conform to ANSI B-2.1, ensuring consistent fit with standard threaded pipe and fittings. Plumbers, pipefitters, and mechanical contractors install this type of hardware in a wide range of low-pressure piping systems. The part weighs 0.04 pounds and is sold individually.

This lock nut is suited for residential and light commercial piping applications where a threaded mechanical connection requires positive locking to resist vibration or inadvertent loosening. It is commonly installed on water, gas, and air distribution lines where galvanized fittings are specified for corrosion protection. Standard threaded pipe configurations in both new construction and retrofit work are typical use cases. Inspectors and contractors specifying galvanized malleable iron fittings under federal and ANSI standards will find this part compliant with the applicable requirements.

Key Features

• Malleable iron construction per ASTM A-197 for ductility and mechanical strength
• Hot-dip galvanized finish per ASTM A-153 for corrosion resistance
• Pipe threads machined to ANSI B-2.1 for consistent fit with standard threaded pipe
• Dimensions conform to ANSI B-16.3 and ANSI B-16.4
• Meets Federal Specification WW-P-521F and WW-P-471-B requirements
• 3/8-inch nominal pipe size, sold individually

Compatibility

Designed as an OEM-style replacement and standard-duty component for 3/8-inch threaded malleable iron piping systems. Suitable for use with standard NPT threaded pipe and fittings meeting ANSI B-2.1 thread specifications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable local codes and IFGC or IPC requirements for the system type. Isolate the line and relieve system pressure before disassembling any threaded connections. Use appropriate pipe wrenches and apply thread sealant or tape as required by the system fluid and code authority. Do not over-torque malleable iron fittings, as the material, while ductile, can crack under excessive force.
