Directedair da03rs-08 Copper Coupling 7/8 in Copper X 7/8 in

Product Description

The DIRECTEDAIR da03rs-08 is a copper coupling with roll stop designed for use in refrigeration and HVAC copper tubing systems. This fitting connects 7/8 inch copper tubing to 7/8 inch copper tubing, providing a reliable, leak-resistant joint in refrigerant line sets and related piping assemblies. The roll stop feature positions the tube end consistently during installation, ensuring proper depth and alignment before brazing. Constructed entirely from copper, this coupling meets industry standards for both dimensional accuracy and material composition. HVAC technicians and refrigeration mechanics use this fitting during new installations, line set extensions, and field repairs.

This coupling is suited for residential and light commercial HVAC and refrigeration applications where 7/8 inch copper tubing is specified. It is commonly installed in suction line connections, line set assemblies, and refrigerant piping where a straight, same-size copper-to-copper joint is required. The roll stop eliminates guesswork on tube insertion depth, which is especially useful in tight or overhead installation scenarios where visual confirmation is limited.

Key Features

• Roll stop design controls tube insertion depth for consistent, repeatable joints
• 7/8 inch copper x 7/8 inch copper connection for same-size tube joining
• Full copper construction meets industry dimensional and material composition standards
• Suitable for brazing in refrigerant and HVAC copper tubing applications
• Certified to industry standards for dimensions and material composition

Compatibility

Designed as an OEM-style replacement and field-use fitting for HVAC and refrigeration systems utilizing 7/8 inch copper tubing in refrigerant line set or piping assemblies.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic. Recover all refrigerant and depressurize the system before cutting or opening any refrigerant line. Clean and deburr tube ends before insertion to the roll stop, and use nitrogen purge during brazing to prevent internal oxidation scaling. Follow applicable mechanical codes and local jurisdiction requirements for refrigerant piping work.
