Reducing Tee, Slip x Slip x FPT PVC Schedule 40 2" x 2" x 1-1/4" (402-250)

This 2" × 1-1/4" Schedule 40 PVC Reducing Tee provides the shallowest available female-threaded reducing branch in the 402-series 2" run sub-group — a single adjacent-size step from a 2" solvent-cemented PVC run down to a 1-1/4" female NPT threaded branch connection in a single fitting. The two 2" slip socket run ports accept standard 2" PVC pipe for solvent cement joining along the through-run, while the 1-1/4" FPT branch outlet receives any compatible 1-1/4" male-threaded fitting, valve, pump port, strainer body, filter vessel inlet, or equipment connection at the branch position without additional adapters or reducing components at the branch face.

Within the 402-series 2" run sub-group, the 402-250 occupies the position closest to the equal tee — the 1-1/4" branch is the largest branch outlet among all reducing variants and requires the smallest size step from the 2" run. This places it in a distinct application context from all four sibling entries. The 402-020 equal tee serves full-size 2" FPT branch connections. The 402-249 makes the most common one-step reduction to the broadly prevalent 1" NPT branch size. The 402-248 makes a two-step reduction to 3/4" for smaller valve and control component connections. The 402-247 makes the deepest three-step reduction to 1/2" for chemical dosing and instrument connections. The 402-250 fills the gap between the equal tee and the 1" reducing variant — serving the 1-1/4" transitional pipe size branch requirement where a component at the branch position presents a 1-1/4" male-threaded inlet rather than the more common 1" or 2" NPT sizes.

The 1-1/4" FPT branch serves a transitional pipe size — the same transitional positioning established across the 829-012, 830-012, and 847-012 entries at 1-1/4" throughout this catalog. The 1-1/4" pipe size bridges the hydraulic gap between 1" and 1-1/2" in commercial and industrial systems, appearing at pump suction and discharge ports, strainer body inlets, filter vessel connections, secondary header branch equipment, and equipment nozzles where the flow requirement exceeds the capacity of 1" but does not justify the full capacity of 1-1/2". At every such 1-1/4" NPT-ported component position in a system where the main run is a 2" cemented PVC pipe, the 402-250 provides the direct, single-fitting connection between the 2" cemented main and the 1-1/4" threaded branch component.

Correctly selecting among the five 402-series 2" run entries is straightforward: the branch outlet size of the downstream threaded component determines the correct fitting. A 2" MPT component calls for the 402-020 equal tee; a 1-1/4" MPT component calls for the 402-250; a 1" MPT component calls for the 402-249; a 3/4" MPT component calls for the 402-248; and a 1/2" MPT component calls for the 402-247. The 402-250 is correct whenever the downstream component at the branch position presents a 1-1/4" male-threaded inlet — regardless of system type, the fitting selection at this position is resolved by the branch component's NPT port size.

The one-step reduction from 2" to 1-1/4" also produces the smoothest hydraulic branch transition of all reducing variants in the sub-group. The minimal size differential between the 2" run and the 1-1/4" branch minimizes the velocity change at the branch entry — a consideration in pump suction branch connections, secondary header feeds, and flow-sensitive equipment supply positions where the hydraulic quality of the branch junction is a design factor alongside the fitting selection.

As with all 402-series mixed-connection fittings, the slip run ports form permanent solvent-cemented joints with the 2" PVC main while the 1-1/4" FPT branch retains the inherent serviceability of a threaded connection — the branch component can be removed and replaced without cutting into the cemented pipe system, preserving access for pump replacement, strainer servicing, equipment changeouts, and filter vessel maintenance throughout the service life of the installation.

Manufactured in white Schedule 40 PVC, this tee delivers reliable performance across commercial, light industrial, and residential piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal tees would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F (governed by the 2" slip run ports), this fitting handles standard pressure service across irrigation, commercial plumbing, pool and spa, water treatment, and light industrial applications at 2". For the slip socket run ports, clean and dry both pipe ends and socket interiors before application. Apply purple PVC primer to all mating surfaces, then apply a uniform coat of medium-body Schedule 40 PVC solvent cement to both the pipe end and socket interior at each run port joint before inserting. Insert each pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Stagger the two run port joints where possible and allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to all male threads engaging the 1-1/4" FPT branch before installing downstream components. Hand-tighten plus one to two turns — do not over-torque PVC female threads at the branch. Apply published pressure derating factors for service temperatures above 73°F.
