Asc Engineered Solutions 318902442 1 in Square Head Plug

Product Description

The ASC ENGINEERED SOLUTIONS 318902442 is a 1-inch cored square head plug made from black steel, designed for use in threaded pipe systems. The cored design allows for future tapping or line extensions without full plug removal. At 0.25 pounds, this fitting is a standard close-out or test-point component used in gas, oil, and industrial piping systems. Licensed plumbers, pipefitters, and HVAC technicians install this type of plug when capping off threaded pipe ends or leaving a port accessible for future service. The square head drive provides positive wrench engagement for reliable installation and removal.

This plug is suited for residential and commercial piping applications where a threaded 1-inch NPT male connection needs to be capped or temporarily sealed. Common install scenarios include gas distribution manifolds, black iron pipe systems, and mechanical room piping headers. The cored center is particularly useful when the fitting may need to be converted to an active port at a later date, saving time on future modifications.

Key Features

• Cored center allows future tapping without full replacement
• Square head profile provides secure 4-point wrench engagement
• Black steel construction for use in gas and oil pipe systems
• 1-inch fitting size for standard NPT threaded connections
• Lightweight at 0.25 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1-inch threaded black iron pipe systems in residential and commercial mechanical applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC. Shut off and depressurize the line before removing or installing any threaded pipe fitting. Apply appropriate thread sealant or PTFE tape to male threads before torquing. Use a properly sized wrench on the square head drive — do not use pipe wrenches directly on the head, as this may deform the drive surface.
