Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 2 1/2" x 1/2" (837-287)

The 837-288 is a 2-1/2" x 3/4" PVC Schedule 80 flush style bushing with a 2-1/2" spigot (male plain end) inlet and a 3/4" slip (socket) outlet, designed to reduce a 2-1/2" socket fitting or pipe hub down to a 3/4" solvent-welded pipe connection within a single compact fitting. The 2-1/2" spigot inlet inserts directly into any standard 2-1/2" Schedule 80 socket fitting or pipe hub and is joined with solvent cement and primer per ASTM D2564, while the 3/4" slip outlet accepts a standard 3/4" PVC pipe end joined the same way — creating a fully solvent-welded, permanent, pressure-rated reducing transition with no threaded connections at either end.

Manufactured from rigid, dark gray PVC compound conforming to ASTM D1784 cell classification requirements, the Schedule 80 wall construction delivers higher pressure ratings and greater mechanical strength than Schedule 40 equivalents at the same pipe size. This makes the 837-288 the correct choice for high-pressure chemical lines, industrial process piping, and any Schedule 80 system where a solvent-welded reducing transition must maintain full Schedule 80 pressure integrity throughout — including installations where the significant 2-1/2" to 3/4" size differential must be bridged in a single fitting without stacking multiple reducers or bushings in series.

The flush style designation distinguishes this bushing from a spigot x slip bushing with a pronounced shoulder — the flush body sits within the receiving socket with a low external profile and no protruding shoulder that would extend beyond the face of the receiving fitting, creating a cleaner, more compact installation in tight piping assemblies and valve manifolds where fitting envelope must be minimized. The spigot x slip end configuration means both connections are permanent solvent welds — appropriate for installations where the reduction point will not require future disassembly and where long-term, leak-free performance under pressure is the priority. The substantial 2-1/2" to 3/4" reduction — the largest step-down relative to inlet size in the standard bushing range — makes the 837-288 the correct single-fitting solution when a large-diameter Schedule 80 socket must be reduced to a small-diameter 3/4" service connection, eliminating the need for intermediate reducing fittings and keeping the transition compact.

Industries & Applications:

• Industrial Process Piping — Single-fitting diameter reductions in high-pressure Schedule 80 chemical distribution and process fluid systems where a 2-1/2" socket fitting or manifold port must be reduced to a 3/4" service or instrument connection without intermediate fittings
• Chemical Processing — Permanent solvent-welded reducing transitions in acid, caustic, and aggressive fluid service where all-PVC Schedule 80 construction eliminates metal corrosion, galvanic incompatibility, and contamination concerns at the reduction point
• Municipal Water & Wastewater — Reducing 2-1/2" socket connections to 3/4" service branches at pump stations, treatment facility manifolds, and distribution system assemblies where a compact, permanent reduction is required
• Irrigation & Agriculture — Reducing large-diameter Schedule 80 socket fittings and manifold ports to 3/4" service connections for zone valves, pressure gauge taps, chemical injection lines, and individual service branches in high-pressure irrigation systems
• HVAC & Mechanical — Permanent solvent-welded reductions in chilled water and condenser water Schedule 80 piping systems where a 2-1/2" socket must be reduced to a 3/4" instrument connection, drain tap, or secondary service line in tight mechanical room assemblies
• Water Treatment & Filtration — Reducing socket connections at filter vessel manifolds, pump assemblies, and chemical dosing equipment to 3/4" service and instrument connections in potable water and industrial water treatment systems
