The CHICAGO FAUCETS XR-10B-12-36-L-ZDC is an X-Riser supply tube designed to connect a faucet or fixture fitting to the water supply line in commercial and residential plumbing installations. The riser is sized at 1/2-inch CTS with an SDR 7 rating and a 0.090-inch wall thickness, providing a robust cross-section for demanding service conditions. One end terminates at a 3/4-inch male NPT fitting, and the overall length runs 36 inches. Plumbers and pipe fitters install this riser as a finished supply connection in restrooms, service sinks, and similar fixture applications.
This riser suits applications where a longer-than-standard supply run is needed between the shutoff valve and the faucet body. The 36-inch length accommodates installations with deep cabinets, exposed chase runs, or where code-required air gaps or service loops add to the required supply length. The 3/4-inch MNPT outlet threads directly into compatible inlet ports on commercial faucet bodies, mixing valves, or shutoff adapters. It is a common component in commercial restroom buildouts and renovation work where Chicago Faucets fixture packages are specified.
Designed as an OEM-style supply riser for commercial plumbing faucet installations requiring a 1/2-inch CTS inlet and a 3/4-inch MNPT outlet connection.
A licensed plumber should install this riser in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and relieve line pressure fully before disconnecting existing supply lines or fittings. Use appropriate thread sealant or tape on the MNPT threads and do not overtighten, as this can crack fittings or distort sealing surfaces. Inspect the CTS end connection and any compression or crimp fitting for leaks after restoring pressure.
