Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 3" x 2" (837-338)

The 3" x 2" PVC Schedule 80 Flush Style Bushing Spigot x Slip (837-338) provides a compact, low-profile inline size reduction from a 3" socket fitting to a 2" pipe continuation, with a flush-mount profile that sits entirely within the receiving socket rather than protruding beyond the face of the fitting. Manufactured from rigid gray PVC conforming to ASTM D1784 Cell Class 12454, this bushing is engineered for the pressure ratings, chemical resistance, and dimensional demands of industrial, municipal, and commercial Schedule 80 PVC piping systems.

The spigot (SPG) end is sized to the outside diameter of 3" Schedule 80 pipe, inserting directly into any standard 3" PVC socket fitting—such as a coupling, tee, cross, elbow, or valve body—as the male solvent-weld member of that joint. Once the spigot end is solvent-cemented into the receiving 3" socket, the bushing becomes a permanent, pressure-rated component of the fitting assembly. The slip (socket) end on the outlet of the bushing then accepts standard 2" Schedule 40 or Schedule 80 PVC pipe via solvent cement, continuing the reduced pipe run from that point forward.

What distinguishes the flush style from a standard hex head bushing is the profile of the flange or shoulder at the base of the spigot. On a standard hex bushing, a raised hex shoulder protrudes beyond the face of the receiving socket, providing a wrench flat for installation but adding axial length to the assembly. The flush style bushing eliminates the protruding shoulder—the bushing sits entirely within the depth of the receiving socket, with its face flush to or recessed within the fitting face. This produces a significantly more compact assembly that is particularly valuable in tight equipment spaces, manifold assemblies, prefabricated skids, and valve trains where fitting-to-fitting clearances are limited and the added axial length of a hex bushing shoulder would create interference or require redesign of the assembly layout.

The flush profile also results in a cleaner, more streamlined interior flow path through the size transition, with the reduction occurring within the socket depth rather than in an external shoulder section—an advantage in flow-sensitive applications where minimizing turbulence and pressure drop through the reducer is an engineering consideration.

At 3" x 2", this bushing spans a meaningful one-size reduction suitable for branch takeoffs from 3" mains, equipment connection adapters, pump inlet reducers, and any Schedule 80 assembly where a 3" socket fitting must transition to a 2" pipe run without the bulk of a standard hex bushing or the complexity of a separate reducing coupling. Schedule 80 construction maintains consistent pressure class with surrounding Schedule 80 pipe and fittings. Gray PVC delivers broad resistance to acids, bases, salts, and a wide range of industrial process fluids. For service temperatures above 140°F, consult CPVC Schedule 80 equivalents.

Industries & Applications:

• Chemical Processing — Compact size reductions inside socket fittings on chemical feed headers, dosing manifolds, and process piping assemblies where a flush profile eliminates axial clearance conflicts in tight equipment layouts
• Water & Wastewater Treatment — Inline reductions on pump station headers, treatment plant process piping, and chemical injection manifolds where Schedule 80 flush bushings provide a compact 3" to 2" transition within an existing socket fitting
• Industrial Manufacturing — Prefabricated Schedule 80 spool assemblies and valve trains where the flush style bushing's low profile is required to meet dimensional constraints in equipment skid layouts
• Irrigation & Agriculture — Mainline to branch size transitions on pump station headers and filter manifolds in Schedule 80 commercial irrigation systems where compact assembly geometry is a design priority
• Municipal Infrastructure — Lift station and treatment plant piping where flush style bushings provide clean, low-profile size reductions within socket fittings on 3" Schedule 80 mains
• Aquaculture & Aquatics — Recirculating system headers and manifold assemblies where compact fitting geometry is required in densely plumbed mechanical spaces
• HVAC & Plumbing — Commercial mechanical systems with Schedule 80 PVC piping requiring a flush-profile reducer bushing at equipment connections and branch points where axial clearance is limited
