Tee, Slip x Slip x Slip PVC Schedule 80 3" x 1/2" (801-333)

The 801-333 is a 3" x 1/2" 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 1/2" slip branch socket off the side — all three connections are solvent-weld, making the entire assembly a fully cemented, permanent, pressure-rated branch fitting with no threaded ports. The two inline run sockets accept standard 3" Schedule 80 PVC pipe, preserving the full bore of the main line through the fitting, while the 1/2" branch socket receives 1/2" PVC pipe for a permanent cemented branch connection off the main run.

The all-slip configuration is the defining distinction between the 801-333 and its direct companion SKU, the 802-333 — which carries an identical run and branch size but features a 1/2" FPT threaded branch port instead of a slip socket. Where the 802-333 is designed to terminate the branch at a threaded gauge, sensor, valve, or instrument connection, the 801-333 is designed to continue the branch into a cemented 1/2" PVC pipe run downstream of the tee. The branch here is a permanent pipe extension — not a threaded port — and once cemented, no connection in the assembly can be disassembled without cutting pipe. If the downstream branch connection requires a threaded male outlet, the 802-333 is the correct specification; if the branch continues as 1/2" cemented PVC pipe for any distance before reaching its endpoint, the 801-333 is the more efficient and hydraulically cleaner choice.

The 3" to 1/2" size differential is the most extreme branch reduction in the 3" Schedule 80 all-slip reducing tee series — a main line of significant flow capacity tapping to a branch one-sixth of the run diameter. As established for the 802-333, this size ratio is not a flow-splitting configuration. The 1/2" branch is a point-connection pipe extension: a small-diameter bypass spur, a chemical injection line that continues as cemented PVC rather than terminating at a threaded fitting, a low-flow recirculation return, a permanent drain spur, a vent connection, or any other minor cemented branch that must originate from the 3" main without reducing the main line bore at the tee point. The full capacity of the 3" main passes through the run sockets undisturbed; the 1/2" branch draws off a defined, minimal portion of that flow through a permanently cemented pipe extension.

The visual size differential between the 3" run sockets and the 1/2" branch socket is the most extreme in the 3" tee series — immediately and unambiguously apparent during installation, with essentially no risk of incorrect pipe insertion by size on the wrong socket. This is a practical installation advantage unique to the most extreme size pairings in the reducing tee category. Proper solvent cementing applies to all three sockets: primer and cement on both surfaces of each joint, pipe inserted to full socket depth on all three connections, and each pipe held in alignment through the set period. At 3" diameter, the run sockets require thorough primer and cement coverage given the larger joint surface area — do not skip the priming step on either run socket.

Schedule 80 wall thickness ensures the fitting meets the pressure and chemical resistance demands of industrial and commercial service environments where Schedule 40 would be underspecified, and the dark gray rigid PVC compound provides broad resistance to acids, bases, and industrial chemicals throughout the service life of the installation.

Specifications:

⚠️ 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 all three sockets — do not skip the priming step on the 3" run sockets at this diameter. The 1/2" branch socket is a cemented pipe extension — if the downstream branch terminates at a threaded valve, gauge, or instrument rather than continuing as PVC pipe, specify the FPT branch version (802-333) instead. Consult manufacturer derating tables for elevated-temperature service.

Industries & Applications:

• Chemical Processing — Introduces a permanent 1/2" cemented chemical injection spur, bypass return line, or small-diameter recirculation pipe off a 3" chemical distribution main, with the all-slip assembly providing a fully solvent-welded, joint-count-minimizing branch connection in corrosive-service piping where eliminating threaded joints at the branch point is a design priority
• Water & Wastewater Treatment — Used on 3" treatment plant distribution headers and process piping mains where a permanent 1/2" PVC pipe branch — rather than a threaded instrument port — must be introduced for a minor drain spur, low-flow sub-circuit, or recirculation return that continues as a cemented pipe run downstream of the branch point
• Industrial Process Piping — Introduces a permanent 1/2" PVC pipe branch off a 3" process line on plant piping and skid assemblies where the branch continues as a cemented run to a downstream drain point, bypass circuit, secondary system, or low-flow sub-circuit rather than terminating at a threaded connection
• Pump Station & Equipment Connections — Installed on 3" pump discharge or suction mains where a permanent 1/2" PVC bypass spur, recirculation line, or drain branch must be introduced as a continuing cemented pipe run off the main rather than as a threaded service port
• Municipal & Utility Infrastructure — Applied on 3" municipal water distribution and pump station mains where a permanent small-diameter 1/2" PVC branch pipe must originate from the main at a defined service point and continue as a cemented run to a downstream drain, blow-off assembly, or minor service connection
• Irrigation & Agricultural Systems — Used on 3" pressurized supply mains where a permanent 1/2" PVC drip zone lateral, chemical injection spur, or low-flow sub-circuit pipe must tie into the main and continue as a fully cemented pipe run downstream of the branch point rather than connecting to a threaded valve or instrument
