Hailiang 11/8cc Roll-stop Copper Coupling 1-1/8in Od

Product DescriptionThe HAILIANG 11/8cc is a roll-stop copper coupling designed for joining 1-1/8-inch outside-diameter copper tubing in refrigeration and plumbing installations. The roll-stop feature is an internal shoulder that positions pipe ends at a fixed depth, ensuring consistent joint alignment before soldering. This eliminates guesswork during assembly and helps produce reliable, leak-free brazed or soldered connections. The coupling is manufactured from copper, making it compatible with standard soft and hard-drawn copper tubing used across HVAC, refrigeration, and plumbing trades. Licensed plumbers and HVAC technicians are the primary installers of this fitting.This coupling is suited for residential and light commercial applications wherever 1-1/8-inch OD copper tubing must be joined or extended. Common scenarios include suction-line repairs, refrigerant piping runs, and potable or non-potable water supply work. The roll-stop design is particularly useful in tight spaces where visual confirmation of pipe insertion depth is difficult. It is sold individually and is intended for use with standard copper tubing meeting ASTM specifications for the applicable service.Key FeaturesRoll-stop internal shoulder sets consistent pipe insertion depth for repeatable joint quality1-1/8-inch outside-diameter sizing fits standard copper tubing used in HVAC and plumbing systemsCopper construction supports both soldering and brazing per applicable trade standardsSold individually, allowing single-piece procurement for service and repair workCompatibilityDesigned as an OEM-style replacement and standard-service fitting for 1-1/8-inch OD copper tubing in residential and commercial HVAC, refrigeration, and plumbing piping systems.Installation NotesInstallation should be performed by a licensed plumber or certified HVAC technician following applicable local codes, including IPC and IFGC requirements for pipe joining. Shut off and recover or isolate the system before cutting into any existing line. Clean and deburr pipe ends, then apply flux per the solder or brazing alloy manufacturers instructions before heating. Do not overheat the fitting, as excessive heat can damage the copper and compromise joint integrity.Technical SpecificationsOutside Diameter: 1-1/8 inchesFitting Type: Roll-Stop CouplingMaterial: CopperUnit of Measure: EachStandard InformationBrand: HAILIANGManufacturer Part Number: 11/8cc
