Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 3/4" x 1/2" (837-101)

This 3/4" x 1/2" Schedule 80 PVC Bushing (Spigot x Slip) provides a compact, all solvent-cement size reduction from a 3/4" socket fitting hub down to a continuing 1/2" socket pipe run, consolidating the 1.5:1 step-down and the hub-to-pipe transition into a single flush-profile fitting body at the elevated pressure performance of Schedule 80 construction. Constructed in dark gray Schedule 80 PVC, it delivers the enhanced pressure rating and chemical resistance of Schedule 80 throughout the joint, making it well-suited for high-pressure irrigation, chemical process, and industrial fluid handling assemblies where the 3/4" to 1/2" adjacent-size socket reduction is the most commonly specified step-down in all-socket PVC distribution systems.

The 3/4" spigot (male plain end) is sized to insert directly into the hub of any standard 3/4" socket-end fitting — tee branch outlet, cross port, coupling end, elbow outlet, side outlet elbow port, or valve body — and is solvent-cemented in place to form a permanent, leak-free joint at the outer face of the hub. The 1/2" slip socket outlet accepts 1/2" PVC pipe for a permanent solvent-cement bond on the downstream reduced-diameter pipe run, continuing the all-socket assembly at 1/2" from the point of the hub reduction. This all-socket Spigot x Slip configuration is the correct choice when the upstream 3/4" assembly is an all-socket Schedule 80 system and the downstream pipe run must continue at 1/2" in the same all-socket cemented construction — distinct from the 838 series (Spigot x FPT) which provides a threaded outlet for a male-threaded downstream component rather than continuing a socket pipe run, from the 839 series (MPT x FPT) which is an all-threaded hex bushing engaging a female-threaded port rather than cementing into a socket hub, and from the 829-101 (Schedule 80 Slip x Slip Reducer Coupling, confirmed in this catalog session) which joins two pipe ends in-line rather than stepping down at a fitting hub location. The flush-profile body keeps the assembled fitting compact within the hub face, avoiding the hex shoulder projection of a standard reducer bushing and minimizing assembly footprint at the socket hub reduction point. At the 3/4" x 1/2" size combination, this bushing is the most widely specified socket-to-socket adjacent-size reduction in all-socket PVC systems — appearing at tee branch outlets, cross ports, and manifold socket hubs throughout high-pressure irrigation, chemical process, and industrial water treatment assemblies where the 3/4" socket main must supply a continuing 1/2" socket distribution or service run.

Rated to approximately 630 psi at 73°F (governed by the 3/4" spigot end), this bushing delivers the elevated pressure performance of Schedule 80 construction — substantially higher than the Schedule 40 equivalent — making it well-suited for demanding process, chemical, and high-pressure irrigation applications where all-socket size reductions at 3/4" fitting hubs must perform at Schedule 80 pressure levels. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to the spigot exterior and the interior of the receiving 3/4" socket hub per ASTM D2564 procedures, inserting fully and holding briefly for initial set. Apply solvent cement separately to the 1/2" pipe end exterior and the fitting's slip socket interior before inserting the pipe fully and maintaining a quarter-turn during assembly for even cement distribution. Allow adequate cure time on both cemented joints before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Steps down 3/4" Schedule 80 socket tee branch outlets, cross ports, manifold hubs, and valve body socket ports to a continuing 1/2" socket PVC pipe run in high-pressure agricultural and municipal irrigation systems where the 3/4" to 1/2" adjacent-size socket reduction is the most common step-down throughout the all-socket Schedule 80 distribution assembly and the elevated pressure rating of Schedule 80 construction is required at each socket hub reduction point
• Chemical Process Piping — Provides a corrosion-resistant all-socket flush-profile size reduction at 3/4" Schedule 80 socket fitting hub ports in systems conveying acids, caustics, fertilizer solutions, and other chemically aggressive fluids where the 1/2" socket downstream run must originate at a 3/4" hub with Schedule 80 pressure performance maintained throughout the all-cemented assembly
• Industrial Process Piping — Transitions 3/4" Schedule 80 socket fitting hub branch outlets and manifold ports to continuing 1/2" socket process water distribution runs, instrument supply lines, and small-bore service branch assemblies in water treatment, manufacturing, and laboratory facilities where all-socket Schedule 80 construction is maintained at every hub reduction point throughout the system
• High-Pressure Irrigation Systems — Serves as the standard 3/4" to 1/2" socket hub reduction fitting in high-pressure drip irrigation, subsurface distribution, and precision agriculture systems where Schedule 80 pressure ratings are required at hub reduction points and the flush-profile body minimizes assembly footprint at each 3/4" socket tee branch or manifold port supplying 1/2" distribution laterals
• Water Treatment & Aquaculture — Used at 3/4" Schedule 80 socket tee branches, cross ports, and manifold hub outlets where the downstream 1/2" socket run must be supplied at Schedule 80 pressure levels with NSF/ANSI 61 compliance required throughout the all-cemented all-socket assembly
• HVAC & Mechanical Systems — Steps down 3/4" Schedule 80 socket fitting hub ports to 1/2" socket service runs on high-pressure cooling tower supply assemblies, chilled water distribution branch lines, and chemically treated water system socket assemblies where Schedule 80 pressure performance is required at hub reduction points throughout the distribution layout
