Tee, Slip x Slip x FPT PVC Schedule 80 1-1/4" x 1" (802-168)

The 1-1/4" x 1" PVC Schedule 80 Reducing Tee Slip x Slip x FPT (802-168) combines three distinct functions in a single fitting: an inline branch takeoff, a run-to-branch size reduction, and a connection-type transition from solvent-weld to female-threaded—delivering a compact, low-component-count solution at any location in a Schedule 80 system where all three of these requirements converge. Manufactured from rigid gray PVC conforming to ASTM D1784 Cell Class 12454, this fitting is engineered for the pressure ratings and chemical resistance demands of industrial, municipal, and commercial Schedule 80 PVC pressure piping.

The two run ends accept standard 1-1/4" Schedule 40 or Schedule 80 PVC pipe via solvent cement, maintaining the 1-1/4" flow path through the run of the tee. The branch outlet is machined with a 1" FPT (female pipe thread) connection conforming to NPT standards, accepting a 1" male-threaded fitting, nipple, valve, instrument, or equipment connection directly—at a reduced size from the main run and without requiring a separate reducing bushing or threaded adapter at the branch.

This three-in-one configuration is the defining value of the 802-168. In a conventional assembly achieving the same result, a contractor would need a standard 1-1/4" slip x slip x slip tee, a 1-1/4" to 1" reducing bushing inserted into the branch socket, and potentially a separate male adapter to transition the branch from slip to threaded—three components, three potential leak points, and a more complex assembly. The 802-168 replaces that entire sub-assembly with a single fitting, reducing fitting count, eliminating intermediate joints, and producing a more compact, field-reliable branch connection at the 1-1/4" to 1" threaded interface.

The 1" FPT branch outlet is appropriately sized for chemical injection ports, pressure gauge connections, flow meter taps, instrument lines, sample ports, and auxiliary service connections where a threaded 1" male-threaded component must attach directly to a 1-1/4" Schedule 80 run without a full-size branch continuation. The threaded branch also retains an inherent serviceability advantage over a solvent-weld branch—the male-threaded component installed in the FPT outlet can be removed and replaced for maintenance, calibration, or reconfiguration without disturbing the solvent-welded run on either side of the tee.

Schedule 80 construction provides greater wall thickness and higher pressure capacity than Schedule 40, making this fitting appropriate for chemical feed systems, industrial process piping, pump station assemblies, and any application where the elevated service demands of Schedule 80 are specified. Gray PVC delivers broad chemical resistance to acids, bases, salts, and a wide range of industrial process fluids. For service temperatures above 140°F, consult CPVC Schedule 80 equivalents.
