Description
Schedule 40 PVC Reducing Bushing (SPG x FPT)
Schedule 40 PVC Reducing Bushing (SPG x FPT) provides a compact transition between different nominal sizes while converting from a spigot connection to a female threaded connection within compatible PVC piping systems. The spigot end fits into a compatible socket connection, while the Female Pipe Thread end accepts an appropriately sized male threaded component.
The Spigot x Female Pipe Thread reducing configuration allows a socket connection to transition to a smaller threaded connection without requiring multiple fittings. Selection should account for both nominal sizes, Schedule 40 PVC compatibility, adjoining fittings and pipe, thread compatibility, solvent-cement joining requirements, 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 connection sizes while changing from a solvent-cement interface to a female threaded outlet. Its spigot end installs into a compatible socket, while the opposite threaded end accepts an appropriately sized male threaded component.
This arrangement can reduce the number of separate fittings required for a size and connection-type transition. Both nominal sizes and connection types should be identified independently before ordering so the bushing matches the receiving socket and the adjoining threaded component.
Spigot Connection
The spigot connection provides the solvent-cement interface of the reducing bushing and is intended to fit into an appropriately sized compatible socket. Proper surface preparation and compatible PVC joining materials are important for establishing the intended permanent connection.
The receiving socket should be checked for correct size and compatibility before assembly. Components should align naturally before solvent cement is applied so the bushing is not used to compensate for improperly positioned piping or fittings.
Female Threaded Connection
The Female Pipe Thread connection accepts an appropriately sized compatible male threaded component and provides the threaded side of the reducing transition. Both nominal thread size and thread compatibility should be verified before assembly.
Threaded PVC connections should be assembled carefully to avoid excessive tightening or mechanical stress on the fitting. Compatible sealing materials and installation practices should be selected according to the piping system and application requirements.
Compact Size & Connection Transition
A Schedule 40 PVC Reducing Bushing provides a space-efficient transition where a compatible socket connection must be reduced to a smaller female threaded connection. The spigot side installs into the receiving socket while the FPT side provides a 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, joining materials, service conditions, piping support, system alignment, and applicable installation practices should be considered during selection.
Installation & Selection Considerations
- Confirm both nominal sizes.
- Verify Schedule 40 PVC compatibility.
- Confirm compatible male pipe thread size.
- Use compatible PVC solvent-cement joining materials.
- Support adjoining piping to avoid stress on the bushing.
Our PVC fitting specialists can help review both nominal sizes, Schedule 40 requirements, Spigot x FPT configuration, receiving socket, adjoining threaded component, intended service conditions, joining requirements, piping support, 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 while changing from a compatible socket connection to a female threaded connection.
What does SPG x FPT mean?
SPG x FPT means the bushing has a spigot connection on one side and a Female Pipe Thread connection on the other.
What makes this a reducing bushing?
The two connection sides are different nominal sizes, allowing the fitting to reduce from one connection size to another.
Where does the spigot end connect?
The spigot end fits into an appropriately sized compatible socket connection for solvent-cement joining.
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, SPG x FPT configuration, adjoining fittings, thread compatibility, joining requirements, and installation conditions.
Important Ordering & Installation Notes
- Confirm both connection sizes.
- Inspect both connections before use.
- Verify compatible male thread dimensions.
- Use compatible PVC solvent cement and procedures.
- Support adjoining piping to minimize fitting stress.
