Bushing, Spigot x Slip (Flush Style) PVC Schedule 80 2-1/2" x 2" (837-292)

The 837-292 is a 2-1/2" x 2" PVC Schedule 80 flush bushing in a spigot x slip (spigot x socket) configuration. The spigot end inserts into a 2-1/2" receiving socket fitting for solvent welding on the inlet side, while the 2" slip socket on the outlet side receives 2" plain-end pipe for solvent welding on the downstream side — making this an all-solvent-weld reducing bushing with no threaded connections at either end.

The all-solvent-weld configuration is the defining characteristic that sets the 837-292 apart from the 838-292, which covers the same 2-1/2" x 2" size reduction but with a female-threaded (FPT) outlet rather than a slip socket. Where the 838-292 is the right choice when the downstream connection is a threaded valve, instrument, or fitting, the 837-292 is the correct specification when the size reduction occurs within a continuous solvent-weld pipe system — the bushing steps the assembly down from 2-1/2" to 2" entirely within the solvent-weld construction, maintaining the pressure integrity and permanence of a fully fused system on both sides of the transition.

The flush style seats completely within the receiving 2-1/2" socket with no protruding hex shoulder at the fitting face — the preferred profile when a clean, low-profile assembly is required or when fitting clearance in the surrounding system is limited. The 2" slip socket on the outlet accepts standard 2" plain-end pipe directly, allowing the downstream pipe run to continue without any intermediate adapter or transition fitting between the bushing and the next pipe section.

The 2-1/2" to 2" size reduction is the most commonly specified single-step reduction at this inlet size, and the all-solvent-weld construction makes the 837-292 particularly well suited for high-pressure industrial systems, chemical distribution headers, and any application where maintaining a fully fused, zero-thread piping system through the size transition is an engineering or specification requirement.

Built to Schedule 80 wall thickness standards from rigid PVC compound, the 837-292 carries the elevated pressure ratings required for demanding industrial and commercial pressure service. Like all Schedule 80 PVC fittings, it is fully resistant to corrosion, chemical attack, and biological fouling — with none of the weight, rust, or galvanic concerns associated with metal reducing fittings of equivalent pressure rating.

Industries & Applications:

• Industrial Process Piping — Reducing a 2-1/2" socket fitting to a 2" solvent-weld pipe run within a fully fused Schedule 80 process system where no threaded transitions are permitted or desired at the size reduction point
• Chemical Processing — Stepping down a 2-1/2" fitting socket to a 2" pipe run in corrosive-fluid distribution systems where all-solvent-weld construction through the size transition maintains full chemical resistance and pressure integrity
• Water Treatment & Municipal — Transitioning between pipe sizes within a continuous solvent-weld Schedule 80 distribution or treatment system where the reduction point must remain fully fused and pressure-rated on both sides
• Irrigation Systems — Reducing a 2-1/2" socket fitting to a 2" solvent-weld pipe continuation on Schedule 80 commercial or agricultural irrigation mainlines where all-plastic, all-solvent-weld construction is specified throughout
• Commercial Plumbing — Installing a compact size reduction within a high-pressure solvent-weld mechanical system where the flush profile keeps the fitting assembly within available clearances
• Industrial HVAC & Cooling — Stepping down from a 2-1/2" fitting socket to a 2" pipe run within a fully solvent-weld chilled water, cooling tower, or chemical treatment piping system
