Coupling, Slip PVC Schedule 80 2-1/2" x 2" (829-292)

The 829-292 is a 2-1/2" x 2" PVC Schedule 80 reducer coupling in a slip x slip (socket x socket) configuration. The 2-1/2" socket end accepts plain-end pipe for solvent welding on the inlet side, while the 2" socket end does the same on the outlet — delivering a permanent, one-step size reduction in a single fitting without the need for bushings, adapters, or intermediate components.

The 2-1/2" x 2" combination is among the most commonly specified one-step reductions in Schedule 80 pressure piping. The two sizes are closely matched in flow capacity, keeping velocity change across the transition gradual and minimizing turbulence and pressure drop through the fitting. This makes the 829-292 a practical choice not only for straightforward pipe size reductions in distribution headers, but also in system designs where maintaining flow efficiency through the transition is an explicit engineering requirement.

Built to Schedule 80 wall thickness standards from rigid PVC compound, this reducer coupling carries the elevated pressure ratings required for demanding industrial and commercial pressure service — meaningfully higher than Schedule 40 equivalents at the same diameter. The all-slip design creates a fully solvent-welded, permanent joint on both ends with no threads to corrode, back out, or leak under pressure cycling or thermal movement.

Like all Schedule 80 PVC fittings, the 829-292 is fully resistant to corrosion, chemical attack, and biological fouling — with none of the weight, rust, or galvanic concerns associated with metal reducer fittings of equivalent pressure rating.

Industries & Applications:

• Industrial Process Piping — Reducing a 2-1/2" Schedule 80 process header to a 2" branch or equipment inlet in a single permanent solvent-weld fitting
• Chemical Processing — Transitioning between pipe sizes in corrosive-fluid distribution systems where Schedule 80 wall thickness and chemical resistance are required at the reduction point
• Water Treatment & Municipal — Connecting mismatched pipe sizes across pumps, meters, and process equipment in treatment plant and distribution infrastructure
• Irrigation Systems — Stepping down a 2-1/2" Schedule 80 mainline to a 2" zone header or equipment connection on commercial or agricultural irrigation systems
• Commercial Plumbing — Reducing high-pressure supply piping from 2-1/2" to 2" in commercial mechanical systems where a compact, single-fitting transition is preferred
• Industrial HVAC & Cooling — Transitioning between pipe sizes in chilled water, cooling tower, or chemical treatment lines where Schedule 80 pressure ratings are specified
