The GEORG FISCHER 837-626 is a flush-style reducer bushing manufactured from Schedule 80 PVC, designed to reduce a 10-inch line down to a 6-inch line within a pressurized or drain piping system. The spigot-by-socket (SPGxS) end configuration allows the bushing to seat inside an existing socket fitting on the larger end while accepting a socket fitting on the reduced end. At 9.23 pounds, this is a substantial fitting suited for industrial, commercial, and heavy-duty residential plumbing installations. Licensed plumbers and pipefitters install this type of reducer bushing when inline diameter transitions are required without adding extra pipe segments or couplings.
This reducer bushing is used in Schedule 80 PVC piping systems where a 10-inch-to-6-inch transition is needed. Typical applications include industrial process piping, commercial plumbing manifolds, irrigation mains, and chemical drainage systems where PVC's corrosion resistance is required. The flush-style design keeps the transition compact and flush with the fitting face, making it well suited for tight-clearance installations or panel-mounted piping configurations.
Designed as an OEM-style replacement or new-installation fitting for Schedule 80 PVC piping systems requiring a 10-inch spigot to 6-inch socket reducer bushing in flush-style configuration.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the system completely before cutting into any existing line. Use a PVC-rated primer and solvent cement rated for Schedule 80 fittings, and allow full cure time before returning the system to service. Do not apply heat or use threaded connections on solvent-weld-only fittings.
