90 Degree Elbow, Slip x FPT PVC Schedule 80 1" x 3/4" (807-131)

The 807-131 is a Schedule 80 PVC 90-degree reducing elbow with a 1-inch slip (socket) inlet and a 3/4-inch female pipe thread (FPT) outlet. The socket end solvent cements onto standard 1" Schedule 40 or Schedule 80 PVC pipe, while the 3/4" FPT outlet receives a 3/4" male-threaded fitting, valve, instrument, or plug connection. By combining a 90° directional change with a simultaneous reduction from 1" to 3/4", this fitting eliminates the need for a separate downstream reducing bushing or adapter — consolidating two functions into a single compact fitting and reducing overall assembly length, joint count, and potential leak points in the system.

The 807-131 sits alongside the 807-130 (1" slip × 1/2" FPT) as the second of the 1" inlet reducing variants in the 807 series, offering a less aggressive step-down for applications where the downstream threaded connection must be 3/4" rather than 1/2". The 3/4" FPT outlet is well suited to branch connections feeding moderately sized threaded valves, instruments, pump ports, and equipment connections — applications where the 1/2" outlet of the 807-130 would be undersized but a same-size 1" x 1" elbow would require a separate downstream reducer. The mixed slip-to-FPT design preserves serviceability at the terminal connection — the upstream cemented joint is permanent, while the 3/4" FPT outlet allows the downstream threaded connection to be broken and reassembled independently for valve replacement, instrument service, or system modification.

Manufactured from heavy-wall Schedule 80 PVC, the 807-131 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 the socket end; apply PTFE thread tape or an approved pipe thread sealant to any male-threaded fitting before engaging the FPT outlet. Do not overtighten threaded connections, as PVC threads can crack under excessive torque.

Industries & Applications:

• Industrial Process Piping — Turns a 1" Schedule 80 PVC process line 90 degrees while stepping down to a 3/4" threaded port for valve connections, instrumentation branches, or equipment inlets in a single fitting, eliminating a separate downstream reducer in corrosion-resistant industrial systems.
• Chemical Processing & Water Treatment — Used at pump discharge branches, filter manifold connections, and chemical metering system tie-ins where a 1" cemented Schedule 80 run must change direction and reduce to a 3/4" threaded interface for equipment compatibility or future serviceability.
• Municipal & Commercial Plumbing — Provides a combined 90° turn and 1" to 3/4" solvent-to-threaded transition at service valves, meter connections, and equipment tie-ins in Schedule 80 commercial plumbing systems where heavier wall construction and a reduced threaded outlet are both specified.
• Irrigation & Agricultural Systems — Installed at pump discharge assemblies, pressure regulator inlets, and control valve bodies where a 1" cemented Schedule 80 mainline must turn and step down to a 3/4" threaded connection for zone control valves, solenoids, or flow regulators.
• Pool & Spa Equipment Rooms — Transitions 1" Schedule 80 chemical feed or auxiliary piping through a 90° bend to a 3/4" threaded pump port, strainer inlet, or equipment manifold connection in permanent equipment room installations.
• Laboratory & Semiconductor Facilities — Directs 1" Schedule 80 PVC reagent, acid waste, or ultrapure water lines through a 90° change of direction while stepping down to a 3/4" threaded instrumentation, dispensing, or equipment connection in confined or fixed-layout spaces.
