1/2" PEX Brass Insert Coupling – Engineered for Secure, Code-Compliant PEX Connections

The 1/2" PEX Brass Insert Coupling provides a durable and mechanically sound solution for joining cross-linked polyethylene (PEX) tubing in potable water and hydronic systems. Manufactured from lead-free brass, this coupling complies with NSF/ANSI 61 and 372 standards and is suitable for systems requiring corrosion resistance, dimensional consistency, and long-term performance under thermal cycling.

Its insert design conforms to ASTM F1807 specifications, ensuring compatibility with crimp ring and clamp connection methods. This component is commonly integrated into PEX installations requiring straightforward inline joining or sectional repairs with minimal system disruption.

Performance Features

  • Lead-Free Brass – Compliant with federal and state lead-free regulations for potable water systems (≤0.25% lead content).
  • ASTM F1807 Standard – Precision-machined insert pattern provides reliable engagement with PEX tubing and approved fittings.
  • Corrosion Resistant – Forged brass body resists dezincification and chemical degradation in closed-loop or chlorinated water systems.
  • High Pressure Rating – Suitable for operating pressures up to 160 PSI at 73°F when installed per manufacturer guidelines.
  • Universal Compatibility – Functions with Type A and Type B PEX when used with corresponding ASTM F1807 or F2159 connection methods.

Technical Specifications

  • Material: Lead-Free Brass
  • Nominal Size: 1/2 inch
  • Connection Type: PEX Insert x PEX Insert
  • Standards: ASTM F1807, NSF/ANSI 61, NSF/ANSI 372
  • Pressure Rating: 160 PSI at 73°F / 100 PSI at 180°F

Installation Overview

This coupling is designed for use with copper crimp rings, stainless steel clamp rings, or other approved PEX connection methods. Proper installation includes cleanly cutting PEX tubing, sliding on the ring or clamp, fully inserting the fitting, and using calibrated tools to complete the connection. Inspection of ring placement and crimp integrity is recommended prior to pressure testing.

Common Applications

Widely used in residential and light commercial plumbing systems, including potable water distribution, hydronic heating, and recirculation lines. Frequently utilized in retrofit work and sectional replacements where code-compliant, lead-free connections are required.

Regulatory Note

All PEX fittings used in potable water systems must comply with the Reduction of Lead in Drinking Water Act. This coupling is certified for use in all 50 states under applicable national and local plumbing codes.

Summary

The 1/2" PEX Brass Insert Coupling offers a durable, code-compliant connection method for PEX systems. Its precision fit, high material integrity, and standard compliance make it a dependable component for professional-grade installations in new and retrofit applications alike.
