Ndl Industries a11205 Copper Union 1-3/8 Inch C X C

Product Description

The NDL INDUSTRIES a11205 is a 1-3/8 inch copper union fitting with a copper-to-copper (C x C) sweat connection on both ends. Unions allow two sections of copper tubing to be connected and disconnected without cutting the line, making them essential for serviceable joints in refrigeration, HVAC, and plumbing systems. This fitting is installed by licensed HVAC technicians and plumbers wherever a mechanically separable joint is required in a copper tubing run.

The a11205 is suited for residential and light commercial applications where 1-3/8 inch OD copper tubing is used. Typical installations include refrigerant suction lines, chilled water piping, and domestic or commercial plumbing supply runs. Its sweat-connect design integrates directly into standard copper tube systems using conventional soldering or brazing techniques.

Key Features

• 1-3/8 inch copper-to-copper (C x C) sweat connection on both ends
• Union design allows future disconnection without cutting tubing
• Compatible with standard soldering and brazing procedures
• Suitable for refrigerant, chilled water, and plumbing applications

Compatibility

Designed as an OEM-style sweat union for use with 1-3/8 inch OD copper tubing in standard HVAC, refrigeration, and plumbing piping systems.

Installation Notes

Installation is performed by licensed HVAC technicians or plumbers. Isolate and recover any refrigerant, or shut off water supply and relieve line pressure before working on the system. Clean and deburr tube ends, apply flux, and join using standard sweat-soldering or brazing methods per applicable codes including IFGC and IPC. Allow joints to cool completely before restoring system pressure.
