Bushing, Spigot x FPT (Flush Style) PVC Schedule 80 6" x 3" (838-530)

The 6" x 3" PVC Schedule 80 Flush Bushing (838-530) transitions a 6" solvent-welded socket connection down to a 3" female-threaded port in a single compact fitting — with a flush-style profile that seats fully recessed within the mating 6" socket rather than projecting outward from its face. The spigot end solvent-welds permanently into any standard 6" Schedule 80 slip socket, while the 3" FPT port accepts any standard 3" male-threaded fitting, valve, adapter, or equipment connection downstream.

The more pronounced size differential of this bushing — 6" inlet to 3" outlet — compared to the 838-532 (6" x 4") makes it well suited to systems where a large-diameter primary header must transition to a significantly smaller threaded service connection: valve isolation points, instrument connections, pump suction or discharge ports, and equipment inlets where a 3" threaded connection is specified against a 6" Schedule 80 main. As with all flush-style bushings, the recessed profile keeps the assembly low-profile within the socket — avoiding the clearance problems and installation constraints that a protruding hex bushing would introduce in tight mechanical spaces or close-coupled valve and equipment configurations.

The slip-to-thread configuration provides practical serviceability at the transition: the solvent-welded 6" upstream joint is permanent and pressure-rated, while the 3" FPT port keeps the downstream connection removable — allowing valves, instruments, strainers, or equipment at the 3" port to be serviced, replaced, or reconfigured without cutting into the primary 6" line.

Manufactured to Schedule 80 specifications and dimensionally compliant with ASTM D2467, the 838-530 delivers the elevated wall thickness and pressure rating that Schedule 80 gray PVC is specified for in chemical processing, industrial fluid handling, and demanding commercial applications. Gray PVC construction provides broad chemical compatibility with acids, alkalis, and industrial process fluids. NSF 61 certification confirms suitability for potable water contact where required.

Industries & Applications:

• Chemical Processing — large-to-small reducing transitions at valves, pumps, and process equipment where a 3" threaded connection must be maintained against a 6" solvent-welded Schedule 80 header without a multi-fitting reduction assembly
• Industrial Process Piping — inline reductions from 6" primary headers to 3" threaded valve, instrument, or equipment connections in plant utility and fluid handling systems
• Water & Wastewater Treatment — reducing transitions in treatment plant process piping where 3" threaded equipment connections integrate with solvent-welded 6" Schedule 80 process headers
• Commercial & Industrial Plumbing — tight-clearance reducing connections in high-pressure mechanical systems where a hex bushing profile would create interference with adjacent piping or equipment
• Aquaculture & Food Processing — corrosion-resistant reducing transitions at equipment and valve connections in recirculating systems and chemical-exposure fluid handling installations
• Irrigation & Agriculture — 6" mainline-to-3" valve or equipment transitions in high-pressure chemical injection and large-scale irrigation distribution systems
