90 Degree Elbow, Slip x Slip PVC Schedule 80 6" x 2" (806-528)

The 6" x 2" PVC Schedule 80 Reducing 90 Degree Elbow (806-528) is a heavy-duty fitting that performs two functions simultaneously — executing a full right-angle direction change while reducing from a 6" slip socket inlet to a 2" slip socket outlet in a single, solvent-welded component. This dual-function geometry eliminates the need to install a standard same-size 90-degree elbow followed by a separate inline reducing coupling or bushing to achieve the same result, consolidating what would otherwise be a two-fitting assembly into one compact component with fewer solvent-weld joints, a smaller installation footprint, and fewer potential leak points through the direction change and reduction zone.

The combination of a 90-degree bend with a pronounced four-size reduction makes the 806-528 a purpose-specific fitting — most commonly specified at the boundary between a large-diameter Schedule 80 supply main or distribution header and a smaller-bore process branch or equipment connection point where the piping must simultaneously change direction and step down in size. This configuration appears frequently at pump discharge headers, equipment inlet connections, skid boundary transitions, and wall or floor penetration points where both the directional change and the size reduction occur at the same physical location in the system layout.

With slip socket connections on both ends, the 806-528 accepts solvent-welded Schedule 80 PVC pipe at the 6" inlet and the 2" outlet — producing a permanently bonded, full-pressure assembly with no threaded interfaces or mechanical connections subject to loosening, corrosion, or leakage under pressure cycling and vibration. The all-solvent construction maintains structural continuity and chemical resistance through the full bend and reduction geometry, delivering the same wall integrity and pressure performance expected from the Schedule 80 pipe system on either side of the fitting.

Manufactured from gray PVC compound meeting ASTM D2467 dimensional standards, the 806-528 provides Schedule 80's higher pressure rating, increased wall thickness, and broad chemical resistance to acids, caustics, solvents, and oxidizing fluids — making it a reliable long-term component in the aggressive industrial, chemical processing, and process piping environments where Schedule 80 reducing elbows at this size combination are most frequently encountered.

Specifications:

Use heavy-bodied solvent cement rated for Schedule 80 PVC on all joints. Confirm that both the 6" and 2" connecting pipe or fittings are Schedule 80 to ensure correct socket interference fit and full rated pressure performance at both ends. The pressure rating differential between the 6" and 2" ends reflects Schedule 80 standard pressure class variation by diameter — system operating pressure must remain within the lower of the two rated values across the full assembly. Thrust restraint or thrust blocking should be evaluated at all 90-degree bends in pressurized buried systems. Pressure-temperature derating applies at elevated service temperatures per ASTM standards. Verify chemical compatibility for non-water service prior to installation.

Industries & Applications:

• Chemical Processing & Transfer — Direction change and inline size reduction at a single location on a 6" Schedule 80 chemical supply header, combining the 90-degree turn and step-down to a 2" process branch or equipment inlet in corrosive acid, caustic, or oxidizing fluid service where Schedule 80 pressure and chemical ratings are required through the full bend and reduction zone
• Industrial Process Piping — Pump discharge headers, skid boundary transitions, and equipment connection points where large-bore Schedule 80 supply piping must simultaneously change direction and reduce to a 2" process line, instrument connection, or secondary feed without a multi-fitting assembly
• Industrial Wastewater & Effluent Handling — Direction changes at neutralization tank outlets, collection header terminals, and transfer system boundaries where a 6" Schedule 80 gravity or pressurized line must turn and reduce to a 2" discharge or transfer connection
• Water & Wastewater Treatment — Process piping direction changes at filter headers, chemical feed manifolds, and aeration supply boundaries where Schedule 80 construction is specified and the piping must simultaneously change direction and step down in size at the equipment or process connection point
• Semiconductor & Electronics Manufacturing — Ultra-pure water (UPW) and chemical distribution systems where Schedule 80 PVC is the material of record and combined direction-change-plus-reduction transitions occur at skid boundaries, wall penetrations, or equipment inlet connections requiring full Schedule 80 continuity through the bend
• Plating & Metal Finishing — Acid, caustic, and process chemical supply piping requiring a corrosion-resistant, pressure-rated combined direction change and size reduction from a 6" supply header to a 2" tank inlet, rinse station feed, or recirculation branch in aggressive surface finishing environments
• Industrial Cooling & HVAC Systems — Cooling tower chemical treatment mains and condenser water distribution systems requiring a Schedule 80 combined elbow and reduction at equipment connection points, secondary circuit inlets, or chemical injection skid boundaries
• Power Generation Facilities — Demineralized water, chemical treatment, and cooling system piping where large-bore Schedule 80 mains require a combined right-angle turn and inline step-down to 2" process, instrumentation, or secondary distribution lines at equipment connection points or facility boundary transitions
