Bushing, Spigot x FPT (Flush Style) PVC Schedule 80 3" x 2" (838-338)

The 3" x 2" PVC Schedule 80 Flush Bushing (Spigot x FPT) provides a compact, pressure-rated transition from a 3" Schedule 80 socket fitting down to a 2" female NPT threaded port. The spigot end inserts directly into the socket of an existing 3" Schedule 80 fitting, while the 2" FPT socket accepts any standard 2" male NPT fitting, valve, equipment connection, or threaded adapter — creating a threaded interface within a solvent-welded system in a single flush-profile fitting body.

Within the 838-series, the 838-338 represents a meaningfully different application profile from the smaller-outlet 838-334 (3" x 3/4"). Where a 3/4" FPT outlet is most commonly used for instrument ports, gauge taps, and minimal-flow branch connections, a 2" FPT outlet is a genuine flow-carrying connection — suitable for secondary service lines, equipment feeds, bypass assemblies, and branch connections where a substantial portion of the main line's flow capacity must pass through the threaded port. The one-size reduction from 3" to 2" is also one of the most practical and frequently encountered reduction steps in commercial and industrial piping, making the 838-338 a broadly applicable fitting across a wide range of system types and service environments.

The flush bushing format keeps the assembly compact by seating the bushing body directly into the host fitting socket without the protruding hex flats of a standard hex bushing — an advantage in tight-clearance mechanical installations and panel piping layouts where wrench access on adjacent fittings would be compromised by the added bulk of a hex profile. Paired with a union on the equipment side of the 2" FPT connection, this bushing becomes the anchor point for a re-joinable equipment interface within a permanent solvent-welded system — a configuration common at pump connections, strainer inlets, and valve bodies in commercial mechanical rooms and industrial process installations.

Manufactured to ASTM D2464 standards and listed under NSF/ANSI 14, the 838-338 is molded from dark gray Schedule 80 PVC compound, delivering the greater wall thickness, elevated pressure ratings, and broad chemical resistance that Schedule 80 specifications demand across industrial, chemical, and commercial service environments.

Industries & Applications:

• Pump Systems & Mechanical Rooms — Installed at 3" Schedule 80 fitting bodies on pump suction or discharge assemblies where the system transitions from a solvent-welded 3" run to a 2" threaded pump port, valve inlet, or strainer connection; commonly paired with a 2" union downstream to preserve serviceability at the equipment interface
• Chemical Processing — Used in 3" Schedule 80 solvent-welded chemical distribution headers to provide a 2" threaded outlet for secondary process lines, chemical sub-feeds, bypass connections, and equipment interfaces in systems handling acids, bases, and aggressive industrial fluids where both pressure integrity and future access are design requirements
• Industrial Manufacturing — Applied in process piping systems where a 3" Schedule 80 solvent-welded main must transition to a 2" threaded connection at equipment inlets, filter housings, strainer bodies, and inline component ports requiring a flush-profile, pressure-rated reduction within the fitting socket
• Municipal Water & Wastewater — Installed at 3" Schedule 80 fitting bodies in pump stations, treatment facilities, and distribution infrastructure where a 2" threaded branch or equipment connection is required within a solvent-welded Schedule 80 system; the flush profile keeps the assembly compact in congested pump station piping layouts
• Commercial Plumbing — Used in mechanical room Schedule 80 piping where a 3" solvent-welded service line must reduce to a 2" threaded connection at a valve body, backflow preventer, equipment inlet, or service branch requiring meaningful flow capacity at the threaded interface
• Irrigation & Agricultural — Applied at pump discharge assemblies, filter station inlets, and valve manifold connections where a 3" Schedule 80 solvent-welded supply fitting must transition to a 2" threaded valve, filter vessel port, or equipment connection in large-scale irrigation infrastructure
• Water Treatment & Filtration — Provides a 2" threaded equipment interface at 3" Schedule 80 fitting connections in multi-stage water treatment systems, filter manifolds, and UV system inlets where a compact, flush-profile threaded reduction is needed within a permanent solvent-welded piping network
