Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 2" x 1-1/4" (837-250)

The 837-250 is a Schedule 80 PVC flush style bushing with a 2-inch spigot (plain end) inlet and a 1-1/4-inch slip (socket) outlet. The spigot end solvent cements directly into any standard 2" Schedule 40 or Schedule 80 PVC socket fitting, while the 1-1/4" socket outlet accepts the outside diameter of standard 1-1/4" Schedule 40 or Schedule 80 PVC pipe via solvent cement — producing a fully cemented, permanent transition from a 2" system to a 1-1/4" downstream pipe run within a single flush-profile fitting. As a flush style bushing, the fitting body sits fully recessed within the receiving socket without protruding hex flats or an exposed shoulder, maintaining a clean, low-profile assembly at the transition point well suited to congested equipment assemblies, manifold headers, and confined mechanical spaces where clearance at the socket face is limited.

The 837-250 occupies the upper portion of the cataloged 2" inlet sub-series in the 837 matrix — above the moderate-flow 837-249 (2" x 1") and the minimal-bore variants below it, and positioned for applications where the downstream 1-1/4" cemented connection must carry substantial flow: high-flow secondary circuit mains, large-bore equipment inlet transitions, primary bypass feeds, and branch connections where 1-1/4" pipe is the specified downstream configuration and the full assembly must remain within a permanently bonded solvent-welded system. The relatively modest 2" to 1-1/4" size reduction also means the hydraulic transition through the fitting is gradual — turbulence and pressure drop at the reduction point are minimized compared to the more aggressive step-downs lower in the sub-series, which is a meaningful advantage in high-flow systems where preserving hydraulic efficiency through every fitting is a design priority.

Where a 1-1/4" female threaded outlet is needed at the same 2" flush inlet, the 838-250 (Spigot x FPT, 2" x 1-1/4") is the corresponding alternative. The all-solvent-cement configuration of the 837-250 is the correct choice when the downstream 1-1/4" connection must be permanent and fully bonded — appropriate for buried lines, concealed installations, and long-term pressure systems where no threaded joint is desired at the reduction. The flush style body keeps the entire 2" to 1-1/4" transition recessed within the 2" socket face, preserving the low-profile assembly geometry that distinguishes both the 837 and 838 series from hex bushing alternatives at the same schedule and size combinations.

Manufactured from heavy-wall Schedule 80 PVC, the 837-250 delivers greater wall thickness and mechanical strength than Schedule 40 equivalents, making it appropriate for industrial, chemical, and elevated-pressure service environments. The dark gray color is standard for Schedule 80 PVC and provides immediate visual identification in mixed-schedule installations. Apply a medium-bodied PVC primer and standard-bodied PVC cement per ASTM D2564 to the 2" spigot end and the receiving socket interior; apply primer and cement separately to the 1-1/4" socket outlet and the pipe OD being inserted into it. Ensure full pipe insertion to the socket stop and maintain joint alignment during the cure set period at the 1-1/4" outlet connection.

Industries & Applications:

• Industrial Process Piping — Reduces a 2" Schedule 80 PVC socket to a permanently bonded 1-1/4" cemented pipe connection in a flush, low-profile assembly for high-flow secondary circuits, substantial bypass supply lines, and large-bore equipment inlet transitions in corrosion-resistant industrial fluid handling systems where an all-cemented reduction at the socket face is specified and fitting clearance is limited.
• Chemical Processing & Water Treatment — Used at pump discharge sockets, filter housing ports, and chemical system headers where a 2" cemented Schedule 80 socket must transition permanently to a 1-1/4" cemented pipe run for high-flow secondary treatment feeds, primary chemical distribution mains, or substantial bypass circuit supply lines within tight equipment assemblies where a fully bonded reduction is preferred over a threaded outlet.
• Municipal & Commercial Plumbing — Provides a flush spigot-to-socket transition at 2" Schedule 80 socket fittings in commercial plumbing systems where a permanent 1-1/4" cemented secondary main, high-flow service branch, or large-bore equipment supply line must be introduced at a socket face without the protruding profile of a hex bushing and without a threaded joint at the reduction point.
• Irrigation & Agricultural Systems — Installed at pump discharge sockets, filter manifold ports, and control assembly headers where a 2" Schedule 80 socket must permanently reduce to a 1-1/4" cemented pipe for high-flow zone lateral mains, primary pressure regulator supply feeds, or substantial secondary distribution circuits in flush-clearance, fully solvent-welded system layouts.
• Pool & Spa Equipment Rooms — Transitions 2" Schedule 80 socket connections to permanently bonded 1-1/4" cemented pipe runs for high-flow auxiliary circulation circuit mains, primary secondary equipment supply lines, and substantial chemical distribution feeds in equipment room installations where a clean, recessed fitting profile and an all-cemented assembly through the transition are both specified.
• Laboratory & Semiconductor Facilities — Provides a flush-profile, fully solvent-welded transition at 2" Schedule 80 socket fittings in ultrapure water, acid waste, or reagent distribution systems where a 1-1/4" permanent cemented high-flow secondary main, primary equipment supply branch, or substantial distribution feed must be introduced at a socket face within confined instrument rack or bench assemblies where threaded joints at the reduction point are not desired.
