Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 6" x 1-1/2" (837-527)

The 6" x 1-1/2" PVC Schedule 80 Flush Bushing (837-527) transitions a 6" solvent-welded socket connection down to a 1-1/2" slip outlet 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 upstream, while the 1-1/2" slip outlet accepts standard 1-1/2" Schedule 80 pipe or a 1-1/2" spigot fitting for a permanent solvent-welded joint downstream.

Stepping one outlet size above the 837-526 (1-1/4" slip outlet), the 837-527 is suited to applications where the downstream permanent run requires the additional flow capacity that a 1-1/2" line provides over a 1-1/4" — dedicated equipment supply lines, fixed recirculation loops, permanent low-to-moderate-flow service runs, and small-diameter branch lines that are specified at 1-1/2" in the system design. The all-slip connection type means both ends of the transition are solvent-welded, producing a fully permanent assembly with consistent joint integrity across both connections. This distinguishes the 837-527 from the 838-series counterpart where the small-end outlet is a female pipe thread for removable downstream connections — the 837-527 is the correct specification when the downstream 1-1/2" connection is a fixed, non-removable element of the system design that will not require access, replacement, or reconfiguration over the system's service life.

The flush-style profile keeps the full assembly recessed within the 6" socket — avoiding the clearance problems, installation constraints, and aesthetic complications that a protruding hex bushing would introduce at this size differential in tight mechanical spaces, congested equipment rooms, or close-coupled valve and instrument configurations. At a 6" inlet to 1-1/2" outlet, the 837-527 accomplishes a significant size step-down in a single fitting that would otherwise require chaining multiple intermediate reducer bushings in sequence, reducing total joint count and keeping the transition point compact and clean within the surrounding assembly.

Manufactured to Schedule 80 specifications and dimensionally compliant with ASTM D2467, the 837-527 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.

Specifications:

Industries & Applications:

• Chemical Processing — permanent low-to-moderate-flow branch connections, fixed equipment supply lines, and dedicated service runs off 6" process fluid headers where a fully solvent-welded, non-removable 1-1/2" downstream transition is specified
• Industrial Process Piping — fixed recirculation loops, permanent drain lines, and dedicated small-diameter service runs from 6" plant utility and process fluid headers where downstream removability is not a design requirement
• Water & Wastewater Treatment — permanent low-to-moderate-flow service connections in treatment plant process piping where a 6" Schedule 80 header transitions to a fixed 1-1/2" downstream run
• Commercial & Industrial Plumbing — tight-clearance permanent size transitions in high-pressure mechanical systems where a fully solvent-welded assembly is preferred and a hex bushing profile would create clearance interference with adjacent piping or equipment
• Aquaculture & Food Processing — permanent corrosion-resistant reducing transitions at fixed equipment supply, recirculation, and service connections in recirculating systems and chemical-exposure fluid handling installations
• Irrigation & Agriculture — permanent service supply and fixed chemical injection runs off 6" high-pressure Schedule 80 mainline headers where non-removable downstream 1-1/2" connections are specified in the system design
