Tee, Slip x Slip x FPT PVC Schedule 80 3/4" x 1/2" (802-101)

This 3/4" × 1/2" Schedule 80 PVC Tee provides a reducing threaded branch outlet off a 3/4" solvent-cemented PVC run, delivering a 1/2" female NPT threaded branch connection in a single fitting. The two 3/4" slip socket run ports accept standard PVC pipe for solvent cement joining along the through-run, while the 1/2" FPT branch outlet receives any compatible 1/2" male-threaded fitting, valve, nipple, or instrument connection without additional adapters.

At 3/4", this tee operates in one of the most common small-bore pipe sizes across commercial, industrial, and light residential Schedule 80 systems — a size frequently encountered at branch supply lines, control valve connections, instrument taps, and chemical injection points where the through-run carries moderate flow volumes and the branch provides a threaded takeoff to a smaller-diameter threaded component. The mixed slip-and-thread configuration is the critical value of this fitting: the 3/4" run remains in the solvent-welded PVC system while the 1/2" FPT branch introduces a threaded interface at the tee body itself, eliminating the need for a separate equal tee plus a downstream threaded adapter at the branch.

This makes the 802-101 particularly efficient wherever the branch connection must interface with a threaded valve, gauge, injector, or instrument — configurations common in chemical dosing systems, irrigation control headers, process sampling lines, and small-bore commercial plumbing branches where a compact, single-fitting solution reduces assembly length and eliminates an extra joint from the pressure envelope.

Manufactured in dark gray Schedule 80 PVC, this tee delivers the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance covers acids, bases, salts, chlorine, and most common process fluids, providing a durable, corrosion-free alternative to metal fittings across demanding service environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 690 psi at 73°F (governed by the 3/4" slip run ends), this tee handles standard to elevated pressure service across a wide range of fluid handling applications. For solvent cement installation at the 3/4" slip ports, clean and dry all pipe ends and socket interiors, apply purple PVC primer to all mating surfaces, then apply a uniform coat of Schedule 80 PVC solvent cement to both the pipe end and socket interior before joining. Insert the pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Stagger the two slip joints where possible and allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the 1/2" FPT branch. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Industrial Process Piping — Installs a 1/2" threaded instrument tap, chemical injection port, pressure gauge connection, or drain outlet off a 3/4" Schedule 80 PVC solvent-welded run in water treatment, chemical processing, and light manufacturing facility piping where a compact threaded branch is needed without interrupting the slip-socket run
• Commercial Plumbing — Provides a 1/2" threaded branch takeoff on a 3/4" PVC water supply run at pressure gauge ports, fixture supply branches, shutoff valve connections, and backflow preventer test cocks in mechanical room and building utility piping
• Chemical Handling & Dosing Systems — Delivers a corrosion-resistant threaded branch point on 3/4" chemical feed lines, reagent distribution headers, and dosing loop piping where the branch must interface with a 1/2" threaded injector, metering valve, or flow meter in aggressive fluid service
• Irrigation & Agricultural Systems — Provides a 1/2" threaded branch tap off a 3/4" PVC pressure lateral at zone control valves, fertigation injection points, pressure regulators, and filter drain connections in commercial irrigation, greenhouse, and agricultural water supply systems
• Water & Wastewater Treatment — Used at sampling ports, instrument taps, and chemical dosing branch connections along 3/4" Schedule 80 PVC process headers in municipal and industrial water treatment and distribution systems
• HVAC & Mechanical Systems — Installed in PVC cooling tower makeup lines, chilled water drain headers, and treated water distribution branches where a 3/4" Schedule 80 run requires a 1/2" threaded outlet for a gauge port, drain cock, or small-bore branch connection
