Bushing, Spigot x Slip (Flush Style)PVC Schedule 80 6" x 2" (837-528)

The 6" x 2" PVC Schedule 80 Flush Style Bushing (Part No. 837-528) is a pressure-rated, gray-body reducer fitting engineered to transition from a 6" fitting socket down to a 2" pipe connection in a single compact component. The spigot (male) end inserts directly into the socket of a 6" fitting — such as a tee, coupling, cross, or valve body — and accepts a solvent-cement joint, while the slip (female socket) end receives a 2" pipe with solvent cement on the outlet side.

The flush style profile is the defining characteristic separating this bushing from a hex bushing in the same size. Rather than a protruding hex shoulder that extends beyond the fitting face and requires a wrench for installation, the flush bushing presents a smooth, low-profile outer surface that seats cleanly within the receiving fitting's socket without added bulk, mechanical projection, or exposed gripping surfaces. This geometry is preferred in inline assemblies, congested mechanical spaces, and installations where a clean, unobtrusive transition is a design or practical requirement.

At 6" × 2", this bushing delivers a four-nominal-size step-down — the most substantial reduction in the 6" flush bushing series, surpassing the 6" × 3" (837-530), 6" × 4" (837-532), and standing alongside the 6" × 1" (837-525) as one of the most extreme reduction ratios available in a single PVC bushing. This size combination is purposefully specified rather than incidentally encountered — a 6" fitting socket receiving a 2" pipe continuation reflects a deliberate flow partitioning or system architecture decision where a large-diameter main must deliver a moderate, well-defined branch flow without the complexity of intermediate reducing hardware.

The 6" × 2" configuration appears most frequently in systems where a 6" main or header distributes to multiple 2" branch circuits, each served by a flush bushing installed in the branch socket of a 6" tee, cross, or manifold fitting. This approach — using a standard 6" fitting plus a reducing bushing rather than a custom reducing tee — gives engineers and contractors maximum flexibility in configuring outlet sizes across a large-diameter header assembly without committing to a fixed reducing fitting for each branch point. It is also a practical solution at equipment connection points where a 6" valve, pump flange, or strainer body must interface with a 2" downstream pipe continuation.

The four-size step-down also makes this bushing a useful specification in chemical processing and water treatment applications where a 6" process main must supply 2" instrumentation, chemical injection, or secondary treatment circuits at multiple points along the main — each transition handled cleanly and compactly by a single flush bushing rather than a stacked adapter assembly.

Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2467 dimensional standards and delivers the increased wall thickness and pressure ratings characteristic of Schedule 80. Compatible with Schedule 80 PVC pipe and solvent cements meeting ASTM D2564.

Industries & Applications:

• Industrial & Chemical Processing — Inline reductions from 6" fitting sockets to 2" pipe continuations on chemical-resistant pressure systems where a large-diameter main or header distributes flow to moderate-capacity 2" branch circuits at tee, cross, or manifold branch points
• Municipal Water & Wastewater — Size transitions from 6" distribution or collection system fittings to 2" service laterals, metering connections, and treatment equipment interfaces where a four-size step-down in a single fitting keeps the assembly compact
• Commercial Plumbing — Mechanical room and equipment room size reductions on large-diameter Schedule 80 systems where a 6" fitting socket must accept a 2" pipe without intermediate coupling or adapter assemblies in tight mechanical spaces
• Chemical Dosing & Water Treatment — Chemical injection supply lines, secondary treatment circuit feeds, and instrumentation supply connections tapped off 6" process mains via flush bushings installed in 6" tee or cross branch sockets
• Irrigation — Pump station and mainline size reductions at 6" tee branch outlets or manifold fittings transitioning to 2" zone feeds and lateral distribution circuits on large-scale agricultural and landscape irrigation systems
• Mining & Oil Field — Corrosive fluid handling systems requiring a compact, single-component inline reduction from 6" fitting sockets to 2" pipe where chemical resistance, joint integrity, and minimal fitting count are active design priorities
• Aquaculture & Water Treatment — Large recirculating system headers and distribution manifolds where a 6" fitting transitions to 2" lateral supply circuits serving individual tank groups, filter stages, or treatment equipment with defined moderate-flow requirements
