Hailiang 11/8x7/8rc Copper Coupling Reducer 1-1/8 X 7/8 Od

Product Description

The HAILIANG 11/8x7/8rc is a copper coupling reducer used to connect two copper tubes of different outside diameters within refrigeration and HVAC piping systems. It transitions from a 1-1/8 inch OD connection to a 7/8 inch OD connection, allowing technicians to join mismatched line sizes without fabricating custom fittings. Copper construction provides reliable thermal conductivity and corrosion resistance suited to refrigerant and ACR tubing applications. HVAC technicians and refrigeration mechanics install this fitting during new construction, equipment changeouts, and service repairs where line size reductions are required.

This coupling reducer is well suited for residential and light commercial HVAC and refrigeration piping where ACR copper tubing requires a diameter transition. It is appropriate for suction or liquid line work where a step-down from 1-1/8 inch OD to 7/8 inch OD is needed. The fitting is sold individually and is intended for brazing into place using standard ACR copper joining procedures.

Key Features

• Reduces from 1-1/8 inch OD to 7/8 inch OD in a single fitting
• Copper construction for compatibility with ACR tubing and refrigerant systems
• OD coupling connections on both ends for standard brazing installation
• Compact reducer profile suited to tight mechanical room and cabinet installations
• Sold as a single unit for precise job-quantity ordering

Compatibility

Designed as an OEM-style replacement or new-installation fitting for ACR copper tube systems requiring a step-down transition from 1-1/8 inch OD to 7/8 inch OD copper tubing.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician following applicable mechanical codes. Recover all refrigerant and depressurize the system before cutting into any refrigerant line. Clean and deburr both tube ends before inserting into the coupling, and braze using an appropriate silver-bearing alloy while flowing dry nitrogen through the line to prevent oxidation scale. Inspect the joint for leaks before recharging the system.
