The AQUALINE 317-1050 is a copper fitting reducer designed to transition between a 1-inch line and a 1/2-inch line in plumbing and hydronic piping systems. This type of fitting is used to step down pipe diameter within a supply or return run, maintaining flow continuity where pipe sizing changes. At 0.1 pounds, it is a compact, lightweight component. Plumbers and pipefitters install this fitting using standard soldering techniques in both residential and light commercial applications.
This reducer is suited for use in domestic water supply lines, radiant heating distribution piping, and general plumbing rough-in work where a 1-inch-to-1/2-inch diameter reduction is required. It is a common component in manifold branch connections, fixture supply drops, and zone piping layouts. The fitting follows standard copper sweat connection practices and fits standard copper tubing dimensions.
Designed as an OEM-style replacement or new-installation fitting for standard copper piping systems requiring a 1-inch to 1/2-inch reducer connection.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before cutting or fitting. Clean and flux both the pipe ends and the fitting sockets thoroughly before applying heat with a propane or MAP torch to ensure a proper solder joint. Allow the joint to cool completely before restoring pressure and checking for leaks.
