The NIBCO INC W01420D is a 1-inch, 45-degree elbow fitting designed for copper pipe installations requiring a directional change in the pipeline. Sold in a package of 10 units, this fitting uses solder cup ends in a FTG x C (fitting-to-copper) configuration, allowing one end to socket directly over tubing while the other accepts standard copper pipe. It is constructed to lead-free standards, making it suitable for potable water systems where material compliance is required. Plumbers and pipefitters rely on this type of fitting for offsets, transitions, and routing changes in both supply and drain configurations.
This elbow is suited for residential and light commercial plumbing applications where copper tubing is the primary piping material. The 45-degree angle allows for gradual directional changes rather than sharp 90-degree turns, which can be useful when routing around obstructions or maintaining flow efficiency. The FTG x C end configuration is commonly used when connecting to existing copper fittings or adapting to copper tubing runs. Each unit in the 10-pack is consistent in dimension and solder cup depth, supporting efficient installations across multiple connections on the same job.
Designed as an OEM-style replacement and standard-use fitting for 1-inch copper tubing systems using sweat-solder connection methods in residential and commercial plumbing installations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully depressurize and drain the line before cutting or fitting any connections. Use appropriate flux and lead-free solder when making sweat connections, and allow joints to cool fully before restoring water pressure. Do not apply flame near combustible materials without proper shielding in place.
