Precision-Engineered 3/4 Inch PEX Brass Insert Coupling – Crimp Connection

The 3/4 inch PEX Brass Insert Coupling from Sioux Chief is built for consistent, high-performance connections in potable water and hydronic distribution systems. Manufactured from lead-free brass, this coupling meets ASTM F1807 and F877 standards for PEX installations and is compatible with crimp ring and clamp connection systems.

Performance Benefits

  • Lead-Free Brass Composition – Ensures compliance with federal Safe Drinking Water Act standards and supports long-term corrosion resistance in potable water lines.
  • Crimp x Crimp Configuration – Provides a secure mechanical connection compatible with ASTM F1807 tools and components.
  • Reliable Sealing – Precision-machined barbs promote a tight seal with PEX tubing, reducing the risk of blowouts or movement under pressure.

Advantages for Field Installation

  • Fast Integration – Ideal for branch line connections and transitions in both residential and commercial piping systems.
  • Tool-Compatible – Installs with standard ASTM-compliant crimp tools and copper crimp rings or stainless clamp rings.
  • Reduced Leak Potential – Maintains pressure integrity through robust fit and long-wearing brass material.

Applications

This coupling is commonly used in cross-linked polyethylene (PEX) installations for cold and hot water distribution, radiant heating loops, and service piping. It’s designed to accommodate tight-space repairs and join runs of identical tubing diameter.
