1/8 inch Copper Coupling with Stop Copper x Copper

1/8 inch Wrot Copper Coupling – Sweat x Sweat

The 1/8 inch copper coupling is engineered for joining two sections of copper tubing with a seamless, rigid connection. Constructed from wrot copper, this fitting offers excellent corrosion resistance, durability under pressure, and thermal conductivity—making it well-suited for both potable water systems and hydronic applications. Its compact form factor makes it ideal for space-constrained installations and precise layout configurations.

This coupling features a sweat (cup) connection on both ends and is designed for soldering. It provides a strong, permanent bond when installed using standard copper plumbing procedures. Lead-free and manufactured in compliance with ASME B16.22 and NSF/ANSI standards, the coupling meets current plumbing codes for use in potable water systems.

Advantages

• Lead-Free Wrot Copper: Safe for drinking water applications and resistant to corrosion and scaling.
• Uniform Wall Thickness: Promotes even heat transfer and consistent solder joint formation.
• Precision Machined Ends: Ensures secure, leak-tight connections with minimal preparation.
• Compact Design: Useful in tight spaces or detailed system layouts.

Technical Specifications

• Size: 1/8 inch nominal
• Material: ASTM B75 Alloy C12200 (Wrot Copper)
• Connection Type: Sweat (C x C)
• Temperature Rating: Up to 400°F (204°C)
• Pressure Rating: 200 psi (when soldered to specification)
• Certifications: NSF/ANSI 61 & 372, ASME B16.22, Lead-Free Compliant

Applications

• Potable water distribution systems
• Hydronic heating loops and closed water circulation
• Residential and commercial copper piping installations
• Low-pressure HVAC piping systems

Installation Notes

Ensure both tubing ends and fitting cups are clean and free of oxidation. Apply appropriate flux and use a lead-free solder to join. Maintain even heat distribution for full solder penetration and a strong bond. Allow joints to cool naturally before pressurizing the system.

With its robust construction and compliance with national plumbing standards, the 1/8 inch copper coupling offers a reliable solution for adapting and extending copper lines in compact system layouts or specialty assemblies.
