Fibre-metal 69029108992 Square Head Plug 1 Inch A105

Product Description

The FIBRE-METAL 69029108992 is a square head plug fitting designed to close off open pipe ends in threaded piping systems. Manufactured to A105 carbon steel material standards, this plug is suited for use in high-pressure and high-temperature applications where a reliable, leak-free seal is required. The square head drive allows for easy installation and removal using a standard wrench or socket. At 1 inch in size, it fits directly into 1 inch NPT female threaded pipe openings. Plumbers, pipefitters, and mechanical contractors install this type of fitting during system pressure testing, pipe capping, or permanent line termination.

This square head plug is used in industrial, commercial, and residential piping systems where threaded pipe connections are standard. Common applications include capping unused branch lines, isolating pipe sections during testing, and permanently terminating threaded runs in gas, water, steam, and hydraulic systems. The A105 carbon steel construction makes it appropriate for use in process piping, mechanical rooms, and similar environments that demand durable forged fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes such as the IPC and IFGC. Depressurize and isolate the pipe system completely before installing or removing any threaded plug fitting. Apply appropriate thread sealant or PTFE tape to the male threads before tightening. Use a properly sized wrench on the square head to achieve a secure, leak-free connection without overtightening the fitting.
