Spears 438-338 3" x 2" PVC Schedule 40 SPGxFPT Reducing Bushing

Spears 438-338 3" x 2" PVC Schedule 40 SPGxFPT Reducing Bushing

The Spears 438-338 is a 3" x 2" PVC Schedule 40 reducing bushing designed for rough-in plumbing runs that step down from 3" pipe to 2" pipe behind the wall or under the floor. It combines a spigot (SPG) end that inserts directly into a 3" PVC socket or fitting with a female pipe thread (FPT) outlet sized to accept 2" male-threaded (MIP) pipe or fittings. Molded from rigid Schedule 40 PVC, the 438-338 matches standard Schedule 40 pipe and fitting dimensions, making it a straightforward choice for plumbers and contractors who need to change pipe diameter without adding a separate coupling and bushing. This reducing bushing is built for concealed, rough-in plumbing work rather than exposed decorative applications, and it keeps the transition to a single molded fitting.

Key Features

• Trade Size: The 3" x 2" reducing bushing steps a 3" PVC line down to 2" pipe or fittings, letting installers change pipe diameter without swapping to a full reducing coupling and adapter.
• Durable Construction: Molded from rigid Schedule 40 PVC, the bushing body stands up to the burial, framing, and concealment conditions typical of rough-in plumbing runs behind walls and under floors.
• SPG x FPT Connection: The spigot (SPG) end slips into a 3" PVC socket or hub while the female pipe thread (FPT) outlet receives 2" male-threaded (MIP) pipe or fittings for a solvent-weld-to-threaded transition.
• Single-Fitting Reduction: Combining the socket and threaded transition in one molded part reduces the number of joints, unions, and fittings needed to step a line down from 3" to 2".
• Schedule 40 Rating: Dimensioned to match standard Schedule 40 PVC pipe and fittings, the 438-338 keeps rough-in tie-ins consistent with the rest of a Schedule 40 PVC piping run.
• Compact Profile: The low-profile bushing design fits tight clearances behind finished walls, in crawlspaces, and under slabs where a longer reducing fitting assembly would not clear framing.
• PVC Material: PVC construction resists the corrosion that can affect metal fittings in concealed, damp rough-in plumbing environments.

Why Spears?

Spears is a well-established manufacturer of PVC and CPVC pipe, fittings, and valves used throughout residential and commercial plumbing systems. The 438-338 reducing bushing is molded from Schedule 40 PVC to hold consistent dimensions with standard Schedule 40 pipe and fittings, giving installers a dependable spigot x FPT transition for 3" to 2" pipe runs. Combining the socket and threaded ends in one fitting simplifies rough-in work by cutting down on the couplings and adapters otherwise needed to change pipe size. Specifying Spears fittings for rough-in plumbing helps keep concealed connections uniform and compatible across a Schedule 40 PVC piping system.
