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

1-1/4 inch Copper Coupling – Wrot Copper C x C for Soldered Joint Connections

The 1-1/4 inch Copper Coupling is a straight, solder-joint fitting used to join two lengths of copper tube of the same nominal size. Manufactured from wrot copper and compliant with ASTM and ANSI standards, this coupling is intended for use in hot and cold potable water systems, HVAC piping, and other pressurized copper installations.

This fitting features two female sweat (cup) ends and is engineered for permanent installation via lead-free soldering. It is designed to be used with Type K, L, or M copper tube depending on system design. The coupling is manufactured to the dimensional and material requirements of ASME B16.22 and ASTM B75, ensuring compatibility and code compliance.

Product Specifications

• Material: Wrot copper (ASTM B75, alloy C12200)
• Size: 1-1/4 inch nominal copper tube size
• Connection Type: Copper x Copper (sweat/solder ends)
• Fitting Type: Straight coupling – C x C
• Compliance: ASME B16.22, NSF/ANSI 61 and 372 (lead-free)

Installation Guidelines

All pipe ends must be cleaned and reamed prior to joining. Use appropriate flux and lead-free solder in accordance with ASTM B813 and ASTM B828. Heat should be applied evenly to ensure full solder flow by capillary action. Joints should be visually inspected and pressure tested as required by applicable plumbing or mechanical codes.

Applications

Typically used in residential and commercial copper piping systems for hot and cold water distribution, chilled water loops, and hydronic heating. Also applicable in repair or retrofit scenarios where straight-line continuity of copper tube is required without changing direction or size.

Material and Compliance Notes

Wrot copper offers excellent corrosion resistance, mechanical strength, and solderability. As of 2014, all fittings used in potable water systems in the U.S. must be certified lead-free per NSF 372. This coupling meets those standards and is suitable for use in systems governed by IPC, UPC, and state-level codes.

The 1-1/4 inch Copper Coupling provides a durable, permanent joint solution for soldered copper systems requiring straight-line connection between pipe sections of identical nominal size.
