90 Degree Elbow, Slip x FPT PVC Schedule 80 3/4" x 1/2" (807-101)

The 807-101 is a 3/4" × 1/2" PVC Schedule 80 90 Degree Elbow with a 3/4" slip (socket) inlet and a 1/2" female pipe thread (FPT) outlet, designed to simultaneously redirect flow by 90 degrees, step down pipe diameter, and transition from a solvent-welded pipe run to a female-threaded connection — all within a single fitting. Where an equivalent assembly using separate components would require a 3/4" equal-bore elbow, a reducing bushing, and a threaded adapter, the 807-101 consolidates all three functions into one compact, solvent-weld-anchored fitting that terminates in a standard 1/2" NPT female thread ready to accept any male-threaded valve, instrument, or equipment connection.

Manufactured from dark gray PVC Schedule 80 compound, this elbow meets ASTM D2467 for the slip socket end and ASTM D2464 for the female pipe thread end, with NSF/ANSI 61 certification covering potable water contact applications. The heavier Schedule 80 wall thickness provides the elevated pressure capacity and chemical resistance required in industrial process environments, chemical handling lines, and high-demand commercial systems — particularly relevant at the threaded FPT outlet, where the additional wall stock reduces the risk of stress cracking at the thread roots under sustained pressure or thermal cycling.

The three-function geometry of this fitting — direction change, size reduction, and connection-type transition — makes it a compact and efficient solution for branch termination runs and equipment connection drops where a 3/4" solvent-weld sub-main must arrive at a 1/2" female-threaded valve, gauge port, or equipment inlet at a right-angle turn. This configuration appears frequently at instrument taps, pressure gauge connections, zone valve inlets, and equipment service ports where layout constraints require the turn and the transition to occur at the same point rather than across multiple fittings in a straight run.

The 3/4" slip end is permanently solvent-cemented to the pipe run during installation — clean, prime, and cement the mating pipe surface using a Schedule 80-compatible PVC cement per ASTM D2564. The 1/2" FPT outlet accepts any standard 1/2" male NPT-threaded fitting; apply PTFE thread tape or an appropriate pipe thread sealant to the mating male threads before assembly to ensure a leak-free joint at the threaded connection. The governing pressure rating for this assembly is determined by the 1/2" FPT end — doubly restrictive as both the smaller size and the threaded connection type; consult Spears' published technical data for this reducing, mixed-connection configuration before specifying to a system working pressure.

Specifications

Industries & Applications

• Industrial Process Piping — Compact turn-and-transition terminations where a 3/4" solvent-welded process or utility water sub-main must arrive at a 1/2" female-threaded instrument port, pressure gauge connection, or equipment inlet at a 90° turn point without a multi-fitting assembly
• Chemical Handling — Corrosion-resistant reducing 90° transitions in chemical transfer and reagent distribution lines where the direction change, size reduction, and connection-type transition must occur at the same point; Schedule 80 wall thickness provides the thread-root integrity required in chemical service
• Water Treatment & Purification — Service connection drops at filter housings, chemical dosing pump inlets, pressure relief ports, and instrumentation taps in municipal and industrial water treatment systems where Schedule 80 is specified and space is constrained
• Commercial Plumbing — Branch termination elbows in commercial mechanical rooms and utility chases where a 3/4" solvent-weld supply line must terminate at a 1/2" female-threaded valve, backflow preventer inlet, or equipment connection at a right-angle turn
• Irrigation & Agriculture — Turn-and-reduce transitions at zone valve female-threaded inlets, chemical injection ports, and pressure gauge taps in Schedule 80-rated agricultural and turf irrigation systems where a 3/4" main feeds a 1/2" threaded component at a 90° transition
• HVAC & Mechanical Systems — Equipment connection elbows in chilled water, condenser water, and cooling tower auxiliary lines where a 3/4" PVC distribution pipe must terminate at a 1/2" female-threaded equipment port or gauge connection at a right-angle turn point
• Laboratory & Analytical Systems — Compact direction-change and connection-transition points in controlled-environment PVC piping where solvent-weld permanence on the supply side and threaded serviceability on the instrument or equipment side are both required in a single compact assembly
