Description
Schedule 80 PVC Flush Style Reducer Bushing (MPT x FPT)
Schedule 80 PVC Flush Style Reducer Bushing (MPT x FPT) provides a threaded transition between different compatible connection sizes using a male pipe thread on the exterior and a female pipe thread on the interior. The flush-style configuration creates a compact threaded reduction where space and connection arrangement are important.
The MPT x FPT reducer bushing configuration allows a compatible female-threaded connection to transition to a smaller compatible male-threaded component through a single fitting. Selection should account for both nominal sizes, Schedule 80 PVC compatibility, mating thread types, required reduction, thread alignment, installation access, and the overall piping arrangement.

Flush-Style Reducer Design
The flush-style reducer bushing configuration combines an exterior male pipe thread with an interior female pipe thread to create a compact threaded size transition. The fitting installs into a compatible female-threaded opening while providing a smaller female-threaded connection for the adjoining male-threaded component.
This arrangement can reduce the number of separate fittings required when transitioning between compatible threaded sizes. Both connection sizes and thread orientations should be confirmed before installation so the reducer bushing matches the intended piping arrangement.
MPT & FPT Connections
The male pipe thread on the exterior of the bushing engages a compatible female-threaded connection, while the internal female pipe thread accepts a compatible male-threaded component. This MPT x FPT arrangement provides the size transition through threaded mechanical connections on both sides of the fitting.
Threaded components should be started carefully and kept properly aligned during assembly. Compatible thread-sealing materials and appropriate installation practices should be used while avoiding unnecessary force that could place excessive stress on the PVC fitting.
Schedule 80 PVC Integration
The Schedule 80 PVC construction allows the reducer bushing to integrate into compatible Schedule 80 PVC piping arrangements requiring a threaded reduction. Matching both nominal connection sizes and thread types to the adjoining components helps maintain the intended connection arrangement.
Application suitability should be evaluated using the requirements of the complete piping system rather than the schedule designation alone. Intended service conditions, adjoining materials, thread compatibility, sealing materials, installation environment, piping support, and applicable practices should all be considered during fitting selection.
Threaded Size Transition
A Schedule 80 PVC Flush Style Reducer Bushing provides a compact method for adapting a larger compatible female-threaded opening to a smaller female-threaded connection. The fitting combines the required reduction and thread transition within a single bushing-style component.
Installation planning should consider both connection sizes, available thread engagement, component alignment, nearby fittings, and working clearance. Adjoining components should align naturally with the bushing so the threaded fitting is not relied upon to correct an offset or support improperly positioned piping.
Installation & Selection Considerations
- Confirm both nominal sizes.
- Verify the required size reduction.
- Check Schedule 80 PVC compatibility.
- Match the MPT and FPT connections correctly.
- Confirm adequate clearance for threaded assembly.

Our PVC fitting specialists can help review your inlet and outlet sizes, Schedule 80 requirements, MPT x FPT configuration, required reduction, mating threaded components, thread compatibility, sealing requirements, piping layout, installation access, and available clearance before you order.
Frequently Asked Questions
What is a Schedule 80 PVC Flush Style Reducer Bushing used for?
It provides a compact threaded transition between different compatible connection sizes using male and female pipe threads.
What does MPT mean?
MPT means Male Pipe Thread and identifies the externally threaded connection designed to engage a compatible female pipe thread.
What does FPT mean?
FPT means Female Pipe Thread and identifies the internally threaded connection designed to accept a compatible male pipe thread.
Why is this fitting called a reducer bushing?
The fitting installs into a larger compatible threaded opening and provides a smaller threaded connection for the adjoining component.
Does this reducer bushing use solvent cement?
No. The MPT x FPT configuration uses threaded mechanical connections rather than socket-style solvent-cement connections.
What should I confirm before ordering?
Confirm both nominal sizes, the required reduction, MPT and FPT connection types, Schedule 80 PVC compatibility, and the mating threaded components.
Important Ordering & Installation Notes
- Inspect both threads before use.
- Confirm both connection sizes.
- Start threaded connections carefully by hand.
- Use compatible thread-sealing materials.
- Avoid excessive force during threaded assembly.
