Tee, Slip x Slip x FPT PVC Schedule 80 3" x 3/4" (802-334)
The 802-334 is a 3" x 3/4" 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 tapping a significantly smaller 3/4" female pipe thread branch off the side — a configuration specifically suited for introducing a threaded instrumentation port, chemical injection point, pressure gauge tap, sampling connection, or small-diameter service branch off a large-diameter main line without interrupting the primary flow path or reducing the main pipe size at that point.
The two inline run sockets accept solvent cement for a permanent, pressure-rated bond to 3" Schedule 80 PVC pipe on both sides, keeping the full bore of the main line intact through the fitting. The 3/4" FPT branch port threads directly onto any male-threaded fitting, valve, gauge, sensor, or equipment connection downstream — no additional slip-to-thread adapter required at the branch point. This combination of a large cemented run and a small threaded branch in a single fitting body is a compact, efficient solution that eliminates the fitting count that would otherwise result from a full-size tee plus a reducing bushing plus a threaded adapter in series.
The 3" to 3/4" branch step is among the most aggressive size differentials in the reducing tee category — a full main line of significant flow capacity tapping to a branch barely a quarter of the run diameter. This size pairing is not a flow-splitting arrangement; it is an instrumentation and service port configuration. The 3/4" branch is not intended to carry a meaningful share of the main flow — it serves a point connection: a pressure relief valve, a chemical injection quill, a pressure transmitter, a sampling valve, a bypass line, or a small-diameter service connection that must tie into the 3" main without requiring the main line fitting to be full-size at the branch.
At 3" run diameter, the 802-334 is sized for commercial and industrial main lines — treatment plant distribution headers, large-diameter chemical process lines, pump station discharge mains, and municipal utility piping — where instrumentation and service connections off the main are a routine design requirement. Schedule 80 wall thickness ensures the fitting meets the pressure and chemical resistance demands of these environments, and the dark gray rigid PVC compound provides broad resistance to the acids, bases, and industrial chemicals commonly encountered in the applications where this fitting is most frequently specified.
Thread sealant tape (PTFE) or pipe dope rated for PVC service should be applied to all male threads assembled into the 3/4" FPT branch port. The run sockets should be primed and cemented per standard PVC solvent welding practice at 3" diameter — do not skip the priming step on large-diameter joints — with pipe held in alignment through the set period before the system is pressurized.

⚠️ Note: In a reducing fitting, the smallest port governs the pressure rating. The 3/4" FPT branch is a service and instrumentation 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. Do not over-tighten threaded connections into the 3/4" FPT port. Use primer before cementing both 3" run sockets — do not skip the priming step at this diameter. Consult manufacturer derating tables for elevated-temperature service.
Industries & Applications:
- Chemical Processing — Provides a 3/4" threaded chemical injection or sampling port off a 3" cemented chemical distribution main, allowing dosing quills, sampling valves, and injection fittings to be connected to the main line with a standard MPT connection without interrupting the primary flow path
- Water & Wastewater Treatment — Used on 3" treatment plant distribution headers and process piping mains where pressure gauge taps, chemical feed points, instrumentation ports, and small-diameter service connections must be introduced off the main line at defined intervals
- Industrial Process Piping — Taps a 3/4" threaded instrument, pressure transmitter, flow sensor, or bypass connection off a 3" process line on plant piping systems and skid-mounted assemblies where the main line must remain full-size and the branch serves a point measurement or control function
- Pump Station & Equipment Connections — Installed on 3" pump discharge or suction mains where a 3/4" threaded branch serves a pressure relief valve, recirculation line, gauge port, or small-diameter bypass connection required for system operation or protection
- Municipal & Utility Infrastructure — Applied on 3" municipal water distribution mains, pump station piping, and treatment facility headers where 3/4" service connections, blow-off valves, and instrumentation taps must be introduced off the main without a full-size branch fitting
- Irrigation & Agricultural Systems — Used on 3" pressurized supply mains where a 3/4" threaded branch connection to a fertilizer injection point, pressure gauge, or flow control device is required off the main distribution line at an irrigation control station or pump outlet
