Cambridge Resources 506160 Black Pipe Plug 1-1/4

Product Description

The CAMBRIDGE RESOURCES 506160 is a 1-1/4 inch black pipe plug used to seal the end of a threaded pipe or fitting opening. Pipe plugs of this type are installed to close off unused ports, test points, or branch connections in piping systems. The black finish indicates a standard black iron or malleable iron construction typical of gas and liquid distribution lines. Plumbers, pipefitters, and HVAC technicians install these fittings during rough-in work, pressure testing, and system modifications where a port needs to be capped off temporarily or permanently.

This plug is suited for residential and light commercial piping applications where a 1-1/4 inch threaded closing fitting is required. It is commonly used in gas distribution piping, hydronic heating systems, and general plumbing supply lines. The single-unit selling format makes it a practical pick for service calls and small installations requiring an individual fitting rather than a bulk pack.

Key Features

• 1-1/4 inch size for standard threaded pipe connections
• Black finish consistent with iron pipe fittings used in gas and hydronic systems
• Plug-style fitting designed to fully close a threaded female port
• Sold as a single unit for targeted repair and service applications

Compatibility

Designed as an OEM-style replacement or service fitting for standard 1-1/4 inch NPT threaded pipe systems in plumbing and HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the system type. Shut off gas or fluid supply and relieve system pressure completely before removing any existing fittings or installing this plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten, as this can crack fittings or damage the female threads in the mating component.
