5/8 inch ID Copper Coupling with Stop Copper x Copper

5/8" ID Copper Coupling – Wrought Copper Fitting for Sweat Connections

The 5/8 inch Inside Diameter (ID) Copper Coupling is a solder joint fitting designed for connecting copper tube in water distribution and hydronic heating systems. Manufactured to ASME B16.22 specifications and suitable for use with ASTM B88 copper tubing, this coupling ensures durable, full-flow joints in both residential and commercial plumbing installations.

Constructed from lead-free wrought copper, the fitting complies with NSF/ANSI 61 and NSF 372 for use in potable water systems. Its seamless interior and uniform wall thickness support capillary solder flow, creating a secure, leak-resistant joint when properly installed with approved soldering methods.

Technical Specifications

• Nominal Tube Size: 5/8 inch ID
• Material: Lead-Free Wrought Copper (≤0.25% lead content)
• Connection Type: Socket x Socket (Sweat/Solder Joint)
• Applicable Standards: ASME B16.22, ASTM B75/B88, NSF/ANSI 61 & 372
• Working Pressure: Up to 200 PSI (water systems)
• Temperature Range: Up to 400°F (depending on solder alloy used)

Product Features

• ✅ Precision Dimensions: Sized to match copper tubing for proper capillary soldering and axial alignment.
• ✅ Seamless Flow: Smooth bore design reduces flow resistance and minimizes pressure drop across the fitting.
• ✅ Corrosion Resistance: Copper's inherent resistance to scaling and degradation supports long-term reliability.
• ✅ Code Compliant: Approved for potable water systems in all jurisdictions requiring lead-free components.
• ✅ Versatile Application: Suitable for water supply, chilled water, heating systems, and non-corrosive fluid transport.

Installation Considerations

Clean tube ends and fitting sockets using an approved abrasive cloth or brush. Apply flux, insert the tube to full depth, and heat joint uniformly before applying solder. Use lead-free solder conforming to ASTM B32. Ensure fittings are properly supported and pressure tested per applicable plumbing codes.

Common Applications

This 5/8" ID copper coupling is used in hot and cold domestic water systems, radiant heating circuits, and mechanical piping applications. It is frequently selected for installations requiring precision-fit soldered connections in confined or concealed spaces.

Code Compliance Note

All copper fittings for potable water use must be certified lead-free per the Safe Drinking Water Act. This product meets those requirements and is listed under NSF/ANSI 61 and 372 for drinking water system components.

Conclusion

The 5/8" ID Copper Coupling provides a durable, code-compliant solution for connecting copper tubing in pressure-rated water systems. Its precision-machined design, corrosion-resistant properties, and compatibility with standard soldering practices make it a reliable choice for plumbing professionals requiring consistent performance in soldered copper joints.
