Tee, Slip x Slip x FPT PVC Schedule 80 3" x 1/2" (802-333)
$22.21
The 802-333 is a 3" x 1/2" Schedule 80 PVC Reducing Tee with Slip x Slip x FPT connections. This fitting maintains a full 3" cemented main run on both inline sockets while introducing a 1/2" female pipe thread branch port off the side — the smallest common NPT branch size available in the 802 series at this run diameter. The two inline run sockets accept solvent cement for a permanent, pressure-rated bond to 3" Schedule 80 PVC pipe on both sides, while the 1/2" FPT branch port threads directly onto any male-threaded fitting, gauge, sensor, valve, or instrument connection downstream.
The 3" to 1/2" size differential is the most aggressive branch reduction in the 802 series at this run diameter — a large-capacity main line tapping to a branch that is one-sixth the run diameter. This extreme size ratio defines the functional role of the fitting precisely: the 802-333 is not a flow-splitting tee and is not intended to divert a meaningful share of main line flow into the branch. It is a point-connection fitting — specifically engineered for introducing a 1/2" NPT instrumentation port, pressure gauge tap, chemical injection point, sensor connection, small-diameter vent, or minor service branch off a 3" main without reducing the main line bore or interrupting the primary flow path at that point.
The 1/2" FPT branch is the standard port size for the majority of industrial instrumentation and inline measurement devices — pressure gauges, pressure transmitters, temperature wells, flow sensors, chemical injection quills, and sampling valves are all routinely available with 1/2" MPT connections. This makes the 802-333 a natural fit for metering and monitoring applications on 3" PVC mains where instrumentation must be introduced at defined points along the line. The FPT branch eliminates the need for a separate slip tee plus a reducing bushing plus a threaded adapter in series, consolidating all three functions — branching, reducing, and thread transition — into a single fitting body at the tap point.
The all-cemented run connection ensures the main line integrity is fully maintained through the fitting. Thread sealant tape (PTFE) or pipe dope rated for PVC service should be applied to all male threads assembled into the 1/2" FPT branch port before installation. At 3" diameter, the run sockets require a full two-step primer and cement application — do not skip the priming step at this diameter — with pipe held in alignment through the set period before pressurizing.

| Specification | Detail |
|---|---|
| Part Number | 802-333 |
| Material | PVC (Polyvinyl Chloride) |
| Schedule | Schedule 80 |
| Fitting Type | Reducing Tee |
| Run Size | 3" x 3" |
| Branch Size | 1/2" |
| Connection Type | Slip x Slip x FPT |
| Run Connection | Slip (Socket) — both ends |
| Branch Connection | FPT (Female Pipe Thread) |
| Color | Dark Gray |
| Pressure Rating | ~600 PSI @ 73°F (1/2" FPT branch governs) |
| Temperature Range | Up to 140°F (60°C) |
| Standard | ASTM D1784, ASTM D2467 |
| End Use | Pressure Systems |
⚠️ Note: In a reducing fitting, the smallest port governs the pressure rating. The 1/2" FPT branch is a point-connection instrumentation and service port — it is not designed to carry a significant share of main line flow. Apply PTFE thread tape or PVC-compatible pipe dope to all male threads assembled into the FPT branch before installation. Do not over-tighten threaded connections into the 1/2" FPT port — small FPT ports are particularly susceptible to thread cracking under excessive torque. Use primer before cementing both 3" run sockets. Consult manufacturer derating tables for elevated-temperature service.
Industries & Applications:
- Chemical Processing — Provides a 1/2" NPT instrumentation or injection port off a 3" cemented chemical distribution main for pressure transmitters, chemical injection quills, sampling valves, and inline sensors — the most common instrument connection size in industrial chemical systems — without requiring a separate adapter assembly at the tap point
- Water & Wastewater Treatment — Used on 3" treatment plant distribution headers and process mains where 1/2" NPT pressure gauge taps, chemical dosing injection points, and inline instrument connections must be introduced at defined intervals along the main without interrupting primary flow or reducing the main line bore
- Industrial Process Piping — Taps a 1/2" NPT pressure transmitter, temperature sensor, flow instrument, or bypass connection off a 3" process line on plant piping and skid assemblies where instrumentation must be integrated into the main at multiple points with minimal fitting count
- Pump Station & Equipment Connections — Installed on 3" pump discharge or suction mains where a 1/2" threaded pressure gauge port, relief valve connection, or small-diameter service branch must be introduced at the pump connection point as part of the standard equipment assembly
- Municipal & Utility Infrastructure — Applied on 3" municipal water distribution mains, metering station piping, and pump station headers where 1/2" NPT service connections, blow-off ports, and instrument taps are required at defined points along the main as part of the system instrumentation and control design
- Irrigation & Agricultural Systems — Used on 3" pressurized supply mains at pump outlet assemblies and control stations where a 1/2" threaded pressure gauge, fertilizer injection point, or flow control instrument must be connected directly to the main line without a separate adapter fitting
