1-1/4 inch Copper Coupling less Stop Copper x Copper

1-1/4" Copper Coupling – Built for Precision and Code-Compliant Installations

The 1-1/4" copper coupling is a seamless solution for joining two lengths of copper tubing in water distribution and mechanical systems. Manufactured from lead-free wrought copper, this coupling supports both residential and commercial applications where code compliance, strength, and long-term reliability are essential.

It is designed to conform to ASTM B88 tubing dimensions and is suitable for use with Type L or Type M copper. The smooth bore and consistent wall thickness support even flow and reduce turbulence, making it ideal for potable water, hydronic heating, and chilled water lines.

Key Features

• ✅ Lead-Free Copper Body: Complies with NSF/ANSI 61 and 372 standards for safe drinking water applications.
• ✅ Sweat Connection (Copper x Copper): Compatible with standard soldering techniques for a permanent, pressure-rated joint.
• ✅ Machined to Tight Tolerances: Ensures smooth insertion and uniform heat transfer during soldering for a strong seal.
• ✅ Resistant to Corrosion: Copper naturally resists degradation from potable water and oxygenated systems.
• ✅ Code-Conforming Design: Approved for use in plumbing systems under UPC, IPC, and local building codes.

Technical Specifications

• Nominal Size: 1-1/4 inch
• Connection Type: Copper x Copper (sweat/solder ends)
• Material: Lead-free wrought copper
• Compliance: NSF/ANSI 61, NSF 372, ASTM B75/B88, ASME B16.22

Typical Applications

Commonly used in hot and cold potable water lines, closed-loop heating systems, and HVAC piping networks. This coupling is also suitable for use in commercial installations requiring fire-resistance-rated plumbing materials. Its compact profile is ideal for retrofits, repairs, and pipe rerouting in confined spaces.

Installation Guidance

Proper installation requires tube end cleaning, application of appropriate flux, and soldering using standard plumbing techniques. Always verify pressure ratings and local plumbing code requirements prior to use. Ensure flame protection is in place when working near combustibles.

Note:

Federal regulations mandate the use of lead-free fittings in potable water systems. This coupling meets or exceeds all current requirements for safety and environmental compliance.

For a clean, durable connection in pressurized copper systems, the 1-1/4" copper coupling offers the mechanical strength and performance demanded by today’s professional tradespeople. Engineered for consistency and built for code compliance, it’s an essential component in any high-integrity piping layout.
