2 inch Copper Coupling less Stop Copper x Copper

2 inch Copper Slip Coupling – Lead-Free, Full-Port Design for Potable Water Systems

This 2 inch Copper Slip Coupling is manufactured for use in residential and commercial water distribution systems. Designed to connect two segments of copper tubing with no internal stop, this full-port slip coupling allows for repair and inline installation when pipe sections need to be joined or replaced. It is compatible with soldering applications and meets NSF/ANSI 61 and 372 standards for potable water use.

Made from lead-free wrought copper, the fitting complies with federal and state-level low-lead requirements. It is intended for use with type L or M copper tubing and is suitable for cold and hot water applications, including domestic supply, hydronic heating, and HVAC systems.

Product Features

• Lead-Free Copper Alloy: Complies with federal Safe Drinking Water Act (SDWA) requirements and ASTM B75/B88 specifications.
• Straight-Through Design: No internal stop allows full slip capability for inline repairs or precise cuts in existing lines.
• Socket Ends: Designed for sweat/solder connection with copper tube. Use with ASTM-compliant flux and solder for code-compliant installations.
• High Temperature Tolerance: Rated for continuous use in hot water systems up to 400°F (204°C) at standard pressures.

Technical Specifications

• Nominal Size: 2 inch
• Material: Lead-Free Wrought Copper
• Connection: Slip x Slip (C x C)
• Applicable Tubing: Type L and Type M Copper
• Certifications: NSF/ANSI 61 & 372, ASME B16.22

Installation Considerations

Install using standard sweat soldering methods. Ensure both pipe ends are clean, deburred, and dry-fit before final assembly. A full-length slip coupling is ideal for repairs where limited pipe movement is available. For pressurized systems, perform a pressure test after soldering and cooling.

Typical Applications

This coupling is widely used in copper potable water systems, hydronic heating lines, and recirculating loops. It is frequently installed during repairs where an internal stop would prevent movement, allowing for a seamless fit between existing pipe sections.

Code Compliance Note

As of 2014, all copper fittings for potable water in the U.S. must comply with lead-free laws. This product meets these standards through its certified low-lead composition and manufacturing processes.

The 2 inch Copper Slip Coupling is a reliable component for professionals requiring durable, code-compliant fittings in water supply installations. Its full-slip configuration provides added flexibility during retrofits, while the lead-free copper construction ensures long service life in potable and hydronic systems.
