1/2 inch Brass Compression Adapter Lead-Free OD x Male

1/2 inch Brass Compression Adapter – Machined for High-Integrity Joints

The 1/2 inch Brass Compression Adapter is engineered for creating secure transitions between compression connections and threaded pipe or fittings in potable water or hydronic systems. Fabricated from lead-free brass, this component complies with NSF/ANSI 61 and 372 for use in drinking water systems across commercial and residential installations.

This fitting includes a precision-machined compression end and a male pipe thread (MPT) outlet, allowing seamless connection between copper tubing and threaded brass, galvanized, or iron pipe assemblies. The hexagonal body profile supports reliable wrench-tightening without distortion of the sealing surfaces.

Product Features

• ✅ Lead-Free Brass Alloy – Conforms to Federal Reduction of Lead in Drinking Water Act for potable water applications.
• ✅ Compression x MPT Configuration – Designed for secure transitions between copper tubing and threaded pipe or valves.
• ✅ High-Precision Threads – NPT threads machined to ANSI/ASME B1.20.1 standards for reliable sealing compatibility.
• ✅ Corrosion-Resistant Finish – Maintains performance and mechanical integrity in variable pressure and temperature conditions.
• ✅ Tool-Compatible Design – Hex-body construction facilitates proper installation using standard open-end or adjustable wrenches.

Technical Specifications

• Material: Lead-free brass (compliant with NSF/ANSI 61, NSF/ANSI 372)
• Size: 1/2 inch OD compression x 1/2 inch MPT
• Connection Type: Compression x Male Pipe Thread
• Pressure Rating: Suitable for up to 200 PSI when properly installed
• Temperature Range: Up to 250°F depending on tubing compatibility

Installation Guidelines

Use of proper ferrules and compression nuts is essential to achieve a reliable seal. Tubing must be clean, deburred, and fully inserted into the compression end before tightening. Avoid over-torquing to prevent deformation. Thread sealant or PTFE tape is recommended on the male threads for enhanced leak protection. Professional-grade installation ensures code compliance and long-term performance.

Typical Applications

This fitting is commonly used in:

• Potable water distribution systems
• Hydronic heating loops
• Fixture supply risers and control valve installations
• Retrofit and repair applications involving dissimilar pipe materials

Code Considerations

Brass compression adapters used in potable systems must be third-party certified to NSF/ANSI 61 and comply with local code requirements. Lead-free brass construction ensures conformance with U.S. Safe Drinking Water regulations.

For professionals requiring dependable sealing in transitional pipe systems, the 1/2 inch Brass Compression Adapter delivers consistent results under pressure. Its material quality, dimensional accuracy, and field-proven design make it a trusted component for building code-compliant installations.
