Description
Schedule 40 PVC Reducing Bushing (MPT x FPT)
Schedule 40 PVC Reducing Bushing (MPT x FPT) provides a compact transition between different nominal sizes using male and female threaded connections within compatible PVC piping systems. The Male Pipe Thread end connects to a compatible female threaded component, while the Female Pipe Thread end accepts an appropriately sized male threaded component.
The Male Pipe Thread x Female Pipe Thread reducing configuration allows a threaded connection to transition to a different nominal size without requiring multiple fittings. Selection should account for both nominal sizes, Schedule 40 PVC compatibility, mating thread sizes, adjoining components, intended service conditions, piping alignment, and available installation clearance.

Reducing Bushing Design
The reducing bushing configuration provides a compact method of transitioning between different nominal threaded connection sizes. Its male threaded end connects to an appropriately sized compatible female threaded component, while the opposite female threaded end accepts a compatible male threaded component.
This arrangement can reduce the number of separate fittings required for a threaded size transition and helps keep the connection compact. Both nominal sizes and mating thread connections should be identified independently before ordering.
Male Threaded Connection
The Male Pipe Thread connection provides the externally threaded side of the reducing bushing and is intended to connect with an appropriately sized compatible female threaded component. Thread size and compatibility should be confirmed before assembly.
Threaded PVC connections should be assembled carefully using compatible sealing materials and installation practices. Excessive tightening should be avoided to help minimize unnecessary mechanical stress on the PVC fitting.
Female Threaded Connection
The Female Pipe Thread connection provides the internally threaded side of the reducing transition and accepts an appropriately sized compatible male threaded component. The mating component should have the correct nominal size and compatible thread configuration.
Components should align naturally during assembly so the bushing is not used to pull misaligned piping into position. Proper piping support can also help reduce mechanical stress at the threaded connections.
Compact Threaded Size Transition
A Schedule 40 PVC Reducing Bushing provides a space-efficient transition where one threaded PVC connection must be reduced to a different nominal size. The MPT side connects to a compatible female thread while the FPT side provides the connection point for a compatible male threaded component.
Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 40 designation alone. Both nominal sizes, thread compatibility, adjoining components, service conditions, piping support, system alignment, and applicable installation practices should be considered during selection.
Installation & Selection Considerations
- Confirm both nominal sizes.
- Verify MPT x FPT configuration.
- Check Schedule 40 PVC compatibility.
- Confirm both mating threaded components.
- Support adjoining piping to minimize fitting stress.

Our PVC fitting specialists can help review both nominal sizes, Schedule 40 requirements, MPT x FPT configuration, mating threaded components, intended service conditions, piping support, system alignment, and available installation clearance before you order.
Frequently Asked Questions
What is a Schedule 40 PVC Reducing Bushing used for?
It provides a compact transition between different nominal sizes using compatible male and female threaded connections.
What does MPT x FPT mean?
MPT x FPT means the bushing has a Male Pipe Thread connection on one side and a Female Pipe Thread connection on the other.
What makes this a reducing bushing?
The two threaded connections are different nominal sizes, allowing the fitting to transition from one connection size to another.
What connects to the MPT end?
The Male Pipe Thread end connects to an appropriately sized compatible female threaded component.
What connects to the FPT end?
The Female Pipe Thread end accepts an appropriately sized compatible male threaded component.
What should I confirm before ordering?
Confirm both nominal sizes, Schedule 40 PVC requirements, MPT x FPT configuration, mating threaded components, service requirements, and installation conditions.
Important Ordering & Installation Notes
- Confirm both connection sizes.
- Verify the MPT x FPT configuration.
- Inspect both threaded connections before use.
- Confirm compatibility with both mating components.
- Support adjoining piping to minimize fitting stress.
