Carrier P805-W1034 Roll-stop Coupling 7/8 in Od Copper

Product Description

The CARRIER P805-W1034 is a roll-stop coupling designed for copper solder-joint piping systems used in supply and pressurized fluid applications. This wrot copper fitting provides a reliable mechanical stop that prevents the fitting from rolling past the intended position during assembly, ensuring consistent joint depth and alignment. At 0.576 pounds and with an outer diameter of 7/8 inches (nominal 3/4 inches), it is a compact, durable component suited for HVAC, plumbing, and refrigeration piping. Licensed plumbers and HVAC technicians rely on this type of fitting for both new construction and retrofit work where precise solder-joint assembly is required.

This coupling is intended for use in supply and pressurized piping systems where copper solder-joint fittings are specified. It fits 7/8 inch OD copper tubing with a 3/4 inch nominal pipe size, making it applicable to a wide range of residential and light commercial HVAC and plumbing installations. The roll-stop design simplifies installation by controlling insertion depth, reducing the risk of improper joint formation in tight or overhead installations.

Key Features

• Roll-stop design controls insertion depth for consistent solder-joint assembly
• 7/8 inch OD fits 3/4 inch nominal copper tubing
• Wrot copper construction for strength and compatibility with solder-joint systems
• Compact geometry: 0.95 x 0.95 x 0.95 inches for use in confined spaces
• Suitable for supply and pressurized fluid piping systems

Compatibility

Designed as an OEM-style solder-joint coupling for 3/4 inch nominal (7/8 inch OD) copper tubing in pressurized supply piping systems.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician following applicable IPC and IFGC guidelines. Shut off and depressurize the system before cutting or joining any pipe. Clean and flux all mating surfaces before applying heat, and allow the joint to cool fully before restoring pressure. Do not overheat the fitting, as excessive heat can compromise the integrity of the solder joint.
