Asc Engineered Solutions 319913604 Malleable Lock Nut

Product Description

The ASC Engineered Solutions 319913604 is a galvanized malleable iron lock nut designed to secure conduit, pipe, or fittings in place at a threaded hub or knockout connection. Weighing 0.25 pounds, this 1-1/2 inch fitting provides a stable mechanical connection point in plumbing, conduit, and pipe installation applications. The galvanized finish offers corrosion resistance suitable for exposed or moderately harsh environments. Plumbers, pipefitters, and electricians use lock nuts like this to draw fittings flush against enclosures or couplings and maintain a tight, rattle-free connection over time.

This lock nut is sized at 1-1/2 inches and is suited for use in residential and light commercial piping or conduit systems where a threaded lockdown connection is required. It is a standard hardware item used during new construction, renovation, and maintenance work wherever conduit bodies, junction boxes, or pipe runs terminate at a threaded opening.

Key Features

• Malleable iron construction allows for reliable thread engagement without cracking under torque
• Galvanized finish provides corrosion resistance in exposed or damp environments
• 1-1/2 inch fitting size is a common standard dimension in plumbing and conduit work
• Lightweight at 0.25 pounds for easy single-hand installation
• Compatible with standard threaded pipe and conduit fittings of the same nominal size

Compatibility

Designed as an OEM-style replacement or standard hardware fitting for use with 1-1/2 inch threaded pipe, conduit, or hub connections in residential and commercial installations.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or electricians depending on the application. Always de-energize any electrical circuit or shut off the relevant water or gas supply before beginning work. Thread the lock nut onto the fitting by hand first, then tighten with an appropriate wrench to a snug fit without overtightening, which can crack malleable fittings. Follow all applicable local codes including NEC for electrical conduit use or IPC for plumbing applications.
