Directedair da03rs-07 Copper Coupling 3/4 Inch Od C X C

Product Description

The DIRECTEDAIR da03rs-07 is a 3/4-inch OD copper coupling with a roll stop, designed for use in HVAC refrigerant and hydronic piping systems. The roll stop feature provides a positive seating point during soldering, ensuring consistent joint depth and alignment. Constructed from copper, this coupling uses a C x C (copper-to-copper) connection type and is non-insulated. Licensed HVAC technicians and plumbers install this fitting during new construction and service work where reliable, pressure-rated copper joints are required.

This coupling is suited for residential and light commercial HVAC applications involving copper tubing runs. The 3/4-inch trade size fits standard Type L and Type M copper tube in refrigerant lines, chilled water lines, and related mechanical piping. It is available in bulk packaging quantities appropriate for contractors managing high-volume install projects.

Key Features

• Roll stop design ensures consistent insertion depth and alignment during soldering
• C x C connection type compatible with standard copper sweat fittings and tools
• Non-insulated construction suitable for a wide range of piping configurations
• Certified to ASME B16.22 dimensional standards for wrought copper fittings
• NSF/ANSI 61 certified for use in systems where potable water contact is a consideration
• Manufactured under ISO 14001 and ISO 9001 certified quality and environmental management systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch OD copper tubing in HVAC equipment applications using C x C sweat connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber following applicable mechanical codes including ASME and local jurisdiction requirements. Shut off refrigerant flow or drain the hydronic system and relieve pressure before cutting into existing lines. Use standard copper tube cutters, deburring tools, flux, and a torch rated for sweat soldering; follow safe brazing or soldering practices and allow joints to cool completely before restoring system pressure. Inspect the joint for full solder fill before returning the system to service.
