Tee, Slip x Slip x FPT PVC Schedule 80 1/2" (802-005)

The 802-005 is a 1/2" PVC Schedule 80 Tee with two slip (socket) run ends and a 1/2" female pipe thread (FPT) branch outlet, designed to introduce a female-threaded branch connection into a solvent-welded 1/2" Schedule 80 pipe run. The two run ends are permanently solvent-cemented to the pipe run on each side of the tee; the FPT branch delivers a standard 1/2" NPT female-threaded outlet that accepts any male NPT-threaded fitting, nipple, instrument body, valve, or equipment port — no solvent cement required at the branch connection and no additional threaded adapter needed to transition from the solvent-welded main line to the threaded branch component.

Manufactured from dark gray PVC Schedule 80 compound, this tee meets ASTM D2467 for the slip socket run ends and ASTM D2464 for the female pipe thread branch, 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 FPT branch, where the additional wall stock at the thread roots reduces the risk of stress cracking under sustained pressure, vibration, or thermal cycling that would be more pronounced in a Schedule 40 fitting of equivalent size.

The defining characteristic of the 802-series over the 801-series at this size is the FPT branch. Where the 801-series Slip × Slip × Slip tee delivers a solvent-weld socket at all three openings — committing the branch to a permanent pipe run — the 802-005 provides a threaded branch outlet that preserves serviceability at the branch connection point. This makes the 802-005 the correct specification wherever the branch connects to a component that may need to be removed, replaced, or serviced without cutting pipe: pressure gauges, temperature sensors, flow meters, relief valves, injection quills, sampling valves, and similar inline instrumentation and equipment that routinely present male NPT threaded connections and benefit from the ability to be backed out of the branch without disturbing the solvent-welded pipe run on either side of the tee.

At 1/2", the 802-005 is among the most commonly specified Schedule 80 mixed-connection tees in small-bore industrial and chemical piping — the 1/2" FPT branch is a standard port size for a wide range of pressure instrumentation, chemical injection equipment, and process monitoring devices, making this fitting the natural branch tee specification wherever a 1/2" Schedule 80 process line must accommodate an instrument or equipment tap that threads in and out of service as part of normal maintenance operations.

Solvent cement installation of both run ends follows standard Schedule 80 procedures — clean, prime, and cement each mating pipe surface using a Schedule 80-compatible PVC cement per ASTM D2564. Allow full joint cure on both run ends before pressurizing the system or threading a component into the FPT branch. The FPT branch accepts any standard 1/2" male NPT 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 branch connection. The governing pressure rating for this assembly is determined by the FPT branch end as the more restrictive connection type; consult the manufacturer's published technical data for the confirmed working PSI at the 1/2" 802-005 before finalizing system design.

Specifications

Industries & Applications

• Instrumentation & Process Controls — Instrument tap tees on 1/2" Schedule 80 process lines providing female-threaded ports for pressure gauges, pressure transducers, temperature sensors, and flow meters that thread directly into the branch without requiring a separate threaded adapter fitting between the tee body and the instrument
• Chemical Handling & Process Piping — Branch tees on 1/2" Schedule 80 chemical transfer, reagent distribution, and dosing lines where an injection quill, sampling valve, or chemical feed port must be introduced at a branch point with a threaded interface that permits component removal without cutting the solvent-welded pipe run
• Water Treatment & Purification — Instrument and equipment branch connections on 1/2" Schedule 80 distribution and treatment lines in municipal and industrial water treatment systems where pressure monitoring ports, chemical dosing inlets, and flow sampling taps require a threaded branch interface anchored in a permanent solvent-welded tee body
• Industrial Process Piping — Serviceable branch connection points on 1/2" Schedule 80 process water, cooling water, and utility water lines where inline valves, strainers, check valves, or relief valves with 1/2" male NPT ports must be installed at a branch takeoff point and may need to be removed or replaced during scheduled maintenance
• Commercial Plumbing — Branch tees in commercial mechanical rooms and utility systems where a 1/2" Schedule 80 supply line must supply a threaded valve, backflow preventer port, or equipment connection at a branch point while maintaining solvent-welded run continuity on both sides of the tee
• Irrigation & Agriculture — Chemical injection tees and pressure monitoring branch points in Schedule 80-rated high-pressure irrigation systems where 1/2" male NPT-threaded injection fittings, pressure gauges, or flow control devices must be introduced at a branch takeoff off the solvent-welded distribution line
• Laboratory & Analytical Systems — Branch connection tees in controlled-environment 1/2" Schedule 80 PVC piping where reagent feed ports, analytical instrument inlets, and sampling valves with male NPT threaded bodies must be installed at branch points with repeatable, solvent-cement-free assembly and disassembly at the branch face
