Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 2" x 1" (837-249)

The 837-249 is a Schedule 80 PVC flush style bushing with a 2-inch spigot (plain end) inlet and a 1-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" socket outlet accepts the outside diameter of standard 1" Schedule 40 or Schedule 80 PVC pipe via solvent cement — producing a fully cemented, permanent transition from a 2" system to a 1" 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 837-249 occupies the practical midpoint of the cataloged 2" inlet sub-series in the 837 matrix — above the minimal-bore 837-247 (2" x 1/2") and 837-248 (2" x 3/4"), which are primarily suited to instrument line feeds, air relief branches, and small-bore drain taps, and positioned instead for applications where the downstream 1" cemented connection must carry moderate flow: secondary circuit feeds, equipment inlet transitions, bypass circuit supply lines, and branch connections where 1" pipe is the specified downstream configuration and the full assembly must remain within a permanently bonded solvent-welded system. The 1" outlet eliminates the need for a separate downstream reducer after the bushing — the fitting directly accepts 1" pipe OD at the socket outlet, keeping joint count and assembly length to a minimum through the reduction point.

Where a 1" female threaded outlet is needed at the same 2" flush inlet, the 838-249 (Spigot x FPT, 2" x 1") is the corresponding alternative. The all-solvent-cement configuration of the 837-249 is the correct choice when the downstream 1" 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" 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 837-249 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" 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" outlet connection.

Industries & Applications:

• Industrial Process Piping — Reduces a 2" Schedule 80 PVC socket to a permanently bonded 1" cemented pipe connection in a flush, low-profile assembly for moderate-flow secondary circuits, bypass supply lines, and 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" cemented pipe run for secondary treatment feeds, moderate-flow chemical distribution branches, or 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" cemented secondary circuit, service branch, or 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" cemented pipe for moderate-flow zone lateral feeds, pressure regulator supply lines, or 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" cemented pipe runs for auxiliary circulation circuit feeds, secondary equipment supply lines, and moderate-flow chemical distribution branches 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" permanent cemented secondary feed, equipment supply branch, or moderate-flow distribution line must be introduced at a socket face within confined instrument rack or bench assemblies where threaded joints at the reduction point are not desired.
