Reducing Tee, Slip x Slip x FPT PVC Schedule 40 3/4" x 3/4" x 1/2" (402-101)
This 3/4" x 3/4" x 1/2" Schedule 40 PVC Reducing Tee (Slip x Slip x FPT) provides a three-way mixed-connection junction that maintains a full 3/4" inline socket run while providing a built-in 1/2" female NPT-threaded branch outlet perpendicular to the run — allowing a 1/2" male-threaded solenoid valve inlet, drip manifold component, filter housing connection, pressure gauge, or small-bore service component to be tapped directly off a 3/4" all-socket pipe run without a separate female adapter or reducer bushing at the branch port. Constructed in white Schedule 40 PVC, it is the mixed-connection reducing service branch tee for the most common small-bore threaded component connection at the dominant 3/4" residential and light commercial irrigation distribution diameter.
The two 3/4" slip socket run ends accept 3/4" PVC pipe for permanent solvent-cement bonds forming the continuous inline run, while the 1/2" FPT branch outlet accepts any standard 1/2" male NPT-threaded fitting, solenoid valve inlet, drip manifold component, pressure gauge connection, filter housing port, or small-bore service component for a pressure-tight mechanical connection when made up with thread sealant or PTFE tape. The built-in 1/2" FPT branch simultaneously provides a size reduction from the 3/4" run diameter to the 1/2" service connection diameter and a socket-to-thread material transition — eliminating both the separate female adapter and the separate reducer bushing that would otherwise be required at a standard 3/4" all-slip tee branch port to accomplish the same result; a single 402-101 replaces what would otherwise require a full-size 3/4" Slip x Slip x Slip tee plus a 3/4" spigot x 1/2" FPT bushing or a full-size 402-007 tee plus a 3/4" x 1/2" reducer hex bushing at the same branch tap location. This Slip x Slip x FPT reducing configuration is the correct choice when the 3/4" socket pipe run must continue on both sides while a 1/2" male-threaded downstream component must be served at the branch — distinct from the 401-095 (3/4" x 3/4" x 1/2" Slip x Slip x Slip, confirmed in this catalog session via spec sheet), which provides a 1/2" socket branch outlet for a continuing cemented 1/2" pipe run rather than connecting a 1/2" male-threaded component; the correct choice between these two confirmed entries at the identical 3/4" run x 1/2" branch size combination is determined entirely by whether the downstream 1/2" branch connection is a male-threaded component (402-101) or a continuing cemented socket pipe run (401-095). At 3/4", this tee most commonly appears in residential landscape irrigation grid manifold assemblies where the 3/4" socket header must supply a 1/2" male-threaded solenoid valve inlet or drip zone manifold component directly at the branch tap; in commercial plumbing 3/4" socket distribution assemblies where a 1/2" male-threaded dedicated fixture valve or service connection must be tapped off the run; and in pump station and process water socket assemblies where a 1/2" male-threaded pressure gauge or instrument component must be incorporated at a 3/4" socket run tap point.
Rated to approximately 480 psi at 73°F (governed by the 3/4" slip run ends), this tee is suited for standard commercial and light industrial pressure service. NSF/ANSI 61 listing confirms suitability for potable water contact.
Apply solvent cement to both the pipe end and fitting socket at each run port per ASTM D2564 procedures, inserting fully and maintaining a quarter-turn during assembly. On the 1/2" FPT branch, use a quality pipe thread sealant or PTFE tape on the male NPT threads of the mating component before engagement. Avoid over-torquing — PVC threads require hand-tight plus one to two turns. Allow adequate cure time on the cemented run joints before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:
- Irrigation & Water Distribution — Taps a 1/2" male-threaded solenoid valve inlet, drip manifold component, filter housing connection, or zone valve body directly off a 3/4" all-socket grid header, sub-main, or distribution run in residential and light commercial irrigation systems where the 3/4" socket run must continue on both sides and a 1/2" male-threaded component must be served at the branch — the most common mixed-connection small-bore service branch tee configuration at the dominant 3/4" residential irrigation distribution diameter
