2 inch Copper Coupling with Stop Copper x Copper

2" Copper Coupling with Stop – Precision-Fit for Pressurized Systems

This 2-inch copper coupling with internal stop is engineered for use in soldered copper tube systems where alignment and flow continuity are critical. The integrated stop ensures proper insertion depth on both ends, facilitating even heat distribution and maintaining consistent pipe spacing during installation.

Manufactured from high-purity wrought copper, this fitting is suitable for use in potable water, hydronic heating, and chilled water applications. It meets current lead-free mandates and is certified for use in pressure-rated systems governed by national and local plumbing codes.

Application Benefits

• ✅ Integrated Center Stop Ensures accurate pipe placement and prevents over-insertion during soldering.
• ✅ Wrought Copper Body Delivers strength and corrosion resistance in high-demand fluid systems.
• ✅ Consistent Inner Diameter Supports full-flow hydraulic performance with minimal turbulence at the joint.

Technical Specifications

• Material: C12200 copper alloy (≥99.9% Cu, phosphorus-deoxidized)
• Nominal Size: 2 inch
• Connection: Copper x Copper, socket ends with internal stop
• Standards: Complies with ASME B16.22, ASTM B75, NSF/ANSI 61 & 372 (lead-free certification)

Installation Considerations

This coupling is designed for use with Type L or M copper tubing. Prior to soldering, pipe ends must be reamed, cleaned, and fluxed. A uniform heat source should be applied to ensure full bond penetration and avoid cold joints. The stop allows for balanced heat application and alignment in horizontal and vertical runs.

Common Use Cases

Typically installed in water supply mains, mechanical rooms, and distribution loops in both commercial and residential settings. The stop feature is particularly beneficial in overhead work or confined spaces where visual alignment is limited.

Regulatory Insight

Per federal law (Reduction of Lead in Drinking Water Act), copper fittings in potable systems must meet low-lead requirements. This component is third-party tested and listed for use in potable and non-potable applications under these provisions.

Specifying fittings with built-in features like stop collars improves installation precision, reduces rework, and supports consistent inspection outcomes. This 2" coupling delivers a professional-grade solution for fluid-tight copper-to-copper connections in a wide range of code-compliant installations.
