1/2 inch Brass Square Head Plug

Reliable Sealing with the 1/2 Inch Brass Square Head Plug

The 1/2 inch Brass Square Head Plug is designed for applications requiring dependable sealing in pressurized or non-pressurized systems. Commonly used to close the end of a female-threaded fitting or pipe, this plug is machined for precision and durability, supporting consistent performance under varying conditions.

Engineered for Performance

Fabricated from lead-free brass, this plug offers a strong resistance to corrosion, scale buildup, and mechanical wear. The square head allows for easy tightening using standard wrenches, particularly in applications where round or hex heads may be less accessible. It is intended for use in both potable and non-potable systems and supports compliance with prevailing codes.

• Material: Lead-free brass for safe use in drinking water systems
• Connection: 1/2 inch Male NPT (National Pipe Thread)
• Head Type: Square head for positive engagement with pipe wrenches or adjustable tools
• Temperature & Pressure Rating: Suitable for moderate pressure service; always verify application requirements

Application and Compatibility

This square head plug is typically used to terminate open pipe runs, provide access points for maintenance or testing, or to close off system branches not currently in use. It is compatible with brass, copper, iron, and PVC fittings that feature female NPT threads. Its corrosion resistance makes it ideal for both indoor and outdoor plumbing configurations, including water, air, and oil lines.

Installation Guidance

Use with approved thread sealant or PTFE tape to ensure a tight, leak-resistant joint. Proper thread engagement (without over-tightening) is key to long-term integrity. Installation should conform to applicable mechanical codes, especially when used in potable water systems.

Typical Use Cases

• Temporary or permanent sealing of system branches
• Test access closure in pressure testing configurations
• Threaded capping of distribution manifolds or fixture stub-outs

Code Compliance

Meets requirements for use in lead-free plumbing systems under the Safe Drinking Water Act and relevant state regulations. Always consult local plumbing codes before installation.

Specify the 1/2 inch Brass Square Head Plug where durability, corrosion resistance, and reliable sealing are essential. This fitting is a field-tested solution for terminating threaded outlets in a wide range of mechanical and plumbing systems.
