Tee, Slip x Slip x Slip PVC Schedule 80 3" x 3/4" (801-334)

The 801-334 is a 3" x 3/4" Schedule 80 PVC Reducing Tee with Slip x Slip x Slip connections. This fitting maintains a full 3" cemented main run on both inline sockets while introducing a significantly smaller 3/4" slip branch socket off the side — all three connections are solvent-weld, making this an entirely cemented, permanent, pressure-rated assembly with no threaded ports. The two inline run sockets accept standard 3" Schedule 40 or Schedule 80 PVC pipe, while the 3/4" branch socket receives 3/4" PVC pipe for a permanent cemented branch connection off the main line.

The all-slip configuration is the key distinction between this fitting and its direct companion SKU, the 802-334 — which carries an identical run and branch size but features a 3/4" FPT threaded branch port instead of a slip socket. Where the 802-334 is designed to terminate at a threaded valve, gauge, or instrument connection, the 801-334 is designed to continue into a cemented 3/4" PVC pipe run downstream of the branch. The branch here is a permanent pipe extension — not a threaded port — and once cemented, neither the branch nor the run connections can be disassembled without cutting pipe.

The 3" to 3/4" branch size differential is among the most aggressive in the reducing tee category and defines the functional role of this fitting. Like the 802-334, this is not a flow-splitting fitting intended to divide equal portions of flow between the run and the branch. At this size ratio, the 3/4" branch serves a specific, limited-flow purpose off a large-capacity 3" main: a small-diameter bypass line, a chemical injection spur, a recirculation return, a vent connection, a drain point, or a permanent small-pipe branch that must tie into the main without reducing the main line bore at the tee point. The main run passes through at full 3" capacity; the 3/4" branch draws off a small, defined portion of that flow or serves as a permanent service connection along the main.

Because the branch is a cemented slip socket rather than a threaded port, the 801-334 is the correct specification when the downstream branch connection is another PVC pipe run — not a threaded valve or instrument. If the branch terminates at a threaded connection, the 802-334 (FPT branch) eliminates the need for a separate slip-to-threaded adapter downstream. If the branch continues as PVC pipe for any distance before reaching its endpoint, the 801-334 is the more efficient and hydraulically cleaner choice.

At 3" run diameter, this fitting is sized for commercial and industrial main lines — treatment plant headers, large-diameter chemical process piping, pump station discharge runs, and municipal utility distribution — where small-diameter permanent branch connections are a routine design element. Schedule 80 wall thickness ensures the fitting meets the pressure and chemical resistance requirements of demanding service environments, and the dark gray rigid PVC compound provides broad resistance to acids, bases, and industrial chemicals throughout the service life of the installation.

⚠️ Note: In a reducing fitting, the smallest port governs the pressure rating. All three sockets are permanent solvent-weld connections — once cemented, no connection can be broken without cutting pipe. Use primer before cementing both 3" run sockets and the 3/4" branch socket — do not skip the priming step at 3" diameter. If the branch will terminate at a threaded valve, gauge, or instrument connection, specify the FPT branch version (802-334) instead to eliminate a downstream adapter fitting. Consult manufacturer derating tables for elevated-temperature service.

Industries & Applications:

• Chemical Processing — Permanently branches a 3/4" PVC chemical spur, bypass line, or recirculation return off a 3" cemented chemical distribution main, with the all-slip assembly providing a fully solvent-welded, chemical-resistant branch connection that eliminates threaded joints in corrosive-service piping
• Water & Wastewater Treatment — Used on 3" treatment plant distribution headers where a permanent 3/4" PVC branch pipe — rather than a threaded instrument or valve port — must be introduced off the main line for small-flow sub-circuits, drain connections, or recirculation spurs
• Industrial Process Piping — Introduces a permanent 3/4" PVC branch run off a 3" process line on plant piping systems and skid assemblies where the branch continues as a cemented pipe run to a downstream component, drain point, or secondary system
• Pump Station & Equipment Connections — Installed on 3" pump discharge or suction mains where a permanent 3/4" PVC bypass, recirculation, or drain branch must be introduced off the main as a continuing pipe run rather than a threaded termination point
• Municipal & Utility Infrastructure — Applied on 3" municipal water distribution and pump station mains where a permanent small-diameter PVC branch pipe must be introduced off the main at a defined service point, with the all-slip assembly preferred for its permanent, joint-count-minimizing installation profile
• Irrigation & Agricultural Systems — Used on 3" pressurized supply mains where a permanent 3/4" PVC branch pipe to a small-flow sub-circuit, drain valve spur, or chemical injection line must tie into the main and continue as a cemented pipe run downstream of the branch point
