Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 6" x 3/4" (837-524)

The 6" x 3/4" PVC Schedule 80 Flush Bushing (837-524) transitions a 6" solvent-welded socket connection down to a 3/4" 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 3/4" slip outlet accepts standard 3/4" Schedule 80 pipe or a 3/4" spigot fitting for a second solvent-welded joint downstream.

The all-slip connection type is the defining characteristic that distinguishes the 837-524 from its threaded counterpart in the 838-series — where the 838-series flush bushings terminate in a female pipe thread for removable downstream connections, the 837-series slip outlet creates a permanent, solvent-welded joint on both ends of the size transition. This makes the 837-524 the right choice when the downstream 3/4" connection is a fixed, permanent part of the system design rather than a serviceable or removable interface — eliminating thread engagement variability, avoiding the need for pipe thread sealant at the small-end joint, and producing a transition point with the same solvent-weld integrity as the surrounding pipe assembly.

At a 6" spigot inlet and 3/4" slip outlet, the 837-524 represents one of the most extreme size differentials available in a single PVC bushing — a transition that would otherwise require chaining multiple reducer bushings or fittings in sequence to achieve. The flush profile keeps the entire assembly recessed within the 6" socket, avoiding the clearance problems and installation constraints that a protruding hex bushing would introduce in tight mechanical spaces, close-coupled valve assemblies, or congested equipment rooms. Typical applications include permanent instrumentation taps, fixed chemical injection quills, vent connections, pressure relief outlets, and small-diameter permanent service lines that must interface directly with a 6" Schedule 80 primary header at a single, compact transition point.

Manufactured to Schedule 80 specifications and dimensionally compliant with ASTM D2467, the 837-524 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 — permanent instrumentation taps, fixed chemical injection quills, and small-diameter service connections off 6" process fluid headers where a fully solvent-welded, non-removable transition is specified at the branch point
• Industrial Process Piping — fixed vent connections, pressure relief outlets, and permanent small-diameter service branch takeoffs from 6" plant utility and process fluid headers where downstream serviceability is not required
• Water & Wastewater Treatment — permanent low-flow instrumentation and service connections in treatment plant process piping where a 6" Schedule 80 header transitions to a fixed 3/4" downstream run
• Commercial & Industrial Plumbing — tight-clearance permanent size transitions in high-pressure mechanical systems where a fully solvent-welded assembly is preferred over a threaded transition and where a hex bushing profile would create interference
• Aquaculture & Food Processing — permanent corrosion-resistant reducing transitions at fixed monitoring, dosing, and vent connections in recirculating systems and chemical-exposure fluid handling installations
• Irrigation & Agriculture — permanent pressure monitoring and chemical injection tap connections off 6" high-pressure Schedule 80 mainline headers where fixed, non-removable downstream connections are specified
