90 Degree Elbow, Slip x Slip PVC Schedule 80 2" x 1-1/2" (806-251)

The 806-251 is a 2" x 1-1/2" PVC Schedule 80 reducing 90° elbow in a slip x slip configuration, combining a 90-degree change of direction with a near-full-bore inline size reduction in a single solvent-weld fitting. The 2" slip inlet accepts standard 2" pipe or a spigot-end fitting for solvent cement bonding, while the 1-1/2" slip outlet transitions the line down one pipe size as it exits the turn — eliminating the need for a separate full-size 90° elbow plus a downstream reducer coupling or bushing.

With only a single pipe size separating inlet from outlet, the 806-251 is the closest-to-full-bore reducing elbow in the 806-series 2" inlet family. The minimal size differential at the turn means flow capacity is largely preserved through the fitting — the 1-1/2" outlet carries a substantial share of 2" mainline flow capacity, making this fitting well-suited for transitions where the direction change and size reduction occur at the same point in the run and the downstream circuit must maintain near-mainline flow.

This near-full-bore characteristic positions the 806-251 for a specific and common real-world scenario: a 2" mainline turns a corner and immediately connects to 1-1/2" downstream equipment, a secondary distribution circuit, or a branch header where the port or pipe size is 1-1/2" by design. In these cases, the reducing elbow bridges both the directional and dimensional mismatch cleanly and permanently in a single fitting — keeping the assembly compact, minimizing joint count, and eliminating the intermediate fitting that a two-piece approach would require.

The all-slip design bonds both ports permanently with solvent cement, producing a clean, monolithic assembly well-suited for buried systems, enclosed mechanical spaces, and any installation where long-term joint integrity outweighs the need for future disassembly at the elbow. Both the 2" inlet and 1-1/2" outlet are joined by standard PVC solvent cement procedure with no threading, O-rings, or mechanical connections involved.

Schedule 80's thicker wall construction delivers higher pressure ratings and stronger resistance to mechanical stress and chemical exposure than Schedule 40, making this elbow a reliable choice for demanding industrial, chemical, and process piping environments. The gray color is the standard Schedule 80 identifier, providing clear visual differentiation from white Schedule 40 components in mixed systems.

Solvent cement installation follows standard PVC practice — clean, prime, and cement both mating surfaces per ASTM D2564 procedures. Confirm the outlet orientation before cementing, as Schedule 80 socket fits leave minimal adjustment time once bonded.

Industries & Applications:

The 806-251 reducing 90° elbow is well-suited for Schedule 80 systems requiring a permanent direction change combined with a near-full-bore size reduction at a single fitting point in a 2" to 1-1/2" transition:

• Industrial Processing — Combined turn-and-reduce connections at pump discharge-to-equipment transitions, distribution header corners, and process line routing changes where a 2" mainline turns and connects to 1-1/2" downstream equipment or secondary circuits in a compact permanent assembly
• Chemical Handling — Permanent solvent-weld direction changes with near-full-bore size reduction in acid, alkali, and reagent distribution systems where minimizing joint count at combined turn-and-reduce points is critical for long-term leak prevention in aggressive chemical environments
• Water & Wastewater Treatment — Combined directional and size transitions in treatment plant piping at pump discharge runs, filter inlet connections, and distribution manifold corners where a 2" supply line turns and connects to 1-1/2" equipment or downstream circuits
• Irrigation & Agriculture — Near-full-bore direction changes with size reduction at mainline-to-lateral transitions in pressurized 2" irrigation systems, consolidating what would otherwise be a two-fitting assembly at routing corners where the downstream lateral or zone supply runs at 1-1/2"
• Commercial & Industrial Plumbing — Reducing 90° connections in cold water supply, equipment feed lines, and mechanical room piping where both a right-angle turn and a 2" to 1-1/2" size change are required at the same routing point
• Aquaculture & Aquatics — Compact direction changes with near-full-bore size reduction in recirculating system headers, pump discharge plumbing, and filter inlet connections where 2" supply lines turn and transition to 1-1/2" equipment connections in permanent solvent-weld installations
• Pool & Spa — Combined turn-and-reduce connections in commercial pool mechanical room piping where 2" primary circulation or equipment supply lines turn corners and connect to 1-1/2" downstream equipment, valve assemblies, or distribution circuits
• HVAC & Cooling Systems — Near-full-bore reducing 90° connections in chilled water and process cooling distribution circuits where a 2" supply header turns and transitions to 1-1/2" secondary circuit or equipment feed lines at the same fitting point
