The LSP ob-373 is a white outlet box supplied with a Rehau PEX center assembly, designed for in-wall plumbing rough-in applications. This unit provides a structured mounting point for PEX supply lines at fixture locations, keeping connections organized and protected behind the finished wall surface. It is typically installed by licensed plumbers during new construction or remodel rough-in, where PEX tubing is run to individual fixture outlets such as washing machines or utility connections.
The ob-373 is suited for residential plumbing installations where Rehau PEX tubing systems are specified. The integrated center assembly aligns with Rehau PEX fitting standards, making it a direct fit for contractors already working within that product ecosystem. The white finish is compatible with standard finish trim and cover plate applications.
Designed as an OEM-style outlet box for residential PEX plumbing rough-in applications using Rehau PEX tubing and fittings.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and depressurize the line before making any connections to the assembly. Secure the outlet box to framing per manufacturer and code requirements before running PEX tubing to the center assembly. Do not overtighten fittings beyond the torque guidance provided by the PEX fitting system manufacturer.
