90 Degree Elbow, Slip x Slip PVC Schedule 80 1" x 3/4" (806-131)

The 806-131 is a Schedule 80 PVC 90-degree reducing elbow with a 1-inch slip (socket) inlet and a 3/4-inch slip (socket) outlet. The 1" socket inlet accepts the outside diameter of standard 1" Schedule 40 or Schedule 80 PVC pipe via solvent cement, while the 3/4" socket outlet accepts the outside diameter of standard 3/4" Schedule 40 or Schedule 80 PVC pipe via solvent cement — producing a fully cemented, permanent 90° directional change with a simultaneous size reduction from 1" to 3/4" in a single compact fitting. By consolidating both functions into one assembly, the 806-131 eliminates the need for a separate downstream reducing bushing or coupling after a same-size 90° elbow, reducing joint count, assembly length, and potential leak points in the system.

The all-slip configuration is the key distinction between the 806-131 and its closest catalog relatives at this size pairing. Where the 807-131 (1" slip × 3/4" FPT) transitions to a threaded outlet for serviceability and equipment compatibility, the 806-131 keeps both connections within a fully solvent-welded assembly — the appropriate choice when the downstream 3/4" connection must remain a permanent cemented joint rather than a serviceable threaded interface. This makes the 806-131 well suited to buried lines, concealed installations, and long-term pressure piping where an all-cemented system is specified from inlet to outlet and no threaded joints are desired at the reduction point.

Manufactured from heavy-wall Schedule 80 PVC, the 806-131 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 both the pipe end and socket interior at each end; ensure full pipe insertion to the socket stop and maintain joint alignment during the cure set period at both the 1" inlet and 3/4" outlet connections.

Industries & Applications:

• Industrial Process Piping — Turns a 1" Schedule 80 PVC process line 90 degrees while simultaneously reducing to 3/4" in a fully cemented assembly, eliminating a separate downstream bushing in corrosion-resistant industrial fluid handling systems where all-solvent construction is specified through the direction change.
• Chemical Processing & Water Treatment — Used at pump discharge transitions, filter manifold connections, and chemical feed line routing changes where a 1" cemented Schedule 80 run must change direction and reduce to 3/4" within a permanently bonded system without introducing a threaded joint at the transition point.
• Municipal & Commercial Plumbing — Provides a combined 90° turn and 1" to 3/4" size reduction in fully cemented Schedule 80 supply and service piping in commercial mechanical rooms and utility spaces where both heavier wall construction and an all-bonded assembly are specified.
• Irrigation & Agricultural Systems — Installed at pump discharge routing changes, filter assembly transitions, and mainline directional offsets where a 1" cemented Schedule 80 run must turn and reduce to 3/4" for downstream zone supply piping, control valve feeds, or lateral distribution lines in a fully solvent-welded system.
• Pool & Spa Equipment Rooms — Transitions 1" Schedule 80 chemical feed or auxiliary piping through a 90° bend while reducing to 3/4" for downstream equipment connections, secondary circuit feeds, or auxiliary branch lines where an all-cemented assembly through the direction change is preferred over a threaded terminal connection.
• Laboratory & Semiconductor Facilities — Directs 1" Schedule 80 PVC reagent, acid waste, or ultrapure water lines through a 90° change of direction while reducing to 3/4" within a fully bonded solvent-welded assembly in fixed-layout systems where permanent cemented joints are specified at all directional transitions.
