Description
Schedule 40 PVC SPG Female Adapter (SPG x FPT)
Schedule 40 PVC SPG Female Adapter (SPG x FPT) provides a transition from a PVC spigot connection to a female pipe thread connection. The adapter allows compatible threaded components to connect with a Schedule 40 PVC socket fitting while maintaining a compact straight-through configuration.
The Spigot x Female Pipe Thread configuration combines a solvent-cement spigot end with an FPT connection for compatible male-threaded components. Selection should account for nominal size, spigot compatibility, thread compatibility, adjoining components, system requirements, and proper installation procedures.

Female Adapter Design
The female adapter design provides a transition between two different connection styles within a straight piping arrangement. One end provides a PVC spigot connection while the opposite end provides a female pipe thread connection.
This configuration allows a compatible male-threaded component to be incorporated into a PVC piping system without using a separate threaded coupling. The nominal size and both connection types should be confirmed before ordering.
Spigot Connection
The spigot end is designed to fit into an appropriately sized compatible PVC socket connection. This end is joined using suitable PVC solvent-cement procedures to create the PVC side of the transition.
The spigot and receiving socket should be clean, properly prepared, and correctly aligned before assembly. Compatible primer, solvent cement, insertion procedures, and required cure times should be followed for the connection.
Female Threaded Connection
The Female Pipe Thread connection accepts a compatible male-threaded piping component or fitting. This provides a removable threaded interface on the opposite side of the solvent-cement spigot connection.
Thread compatibility and engagement should be confirmed before installation. The threaded connection should be assembled using appropriate procedures while avoiding excessive tightening that could place unnecessary stress on the PVC adapter.
Spigot-to-Thread Transition
A SPG x FPT adapter provides a compact transition between a PVC socket fitting and a male-threaded component. The adapter combines the two connection methods without changing the direction of the piping run.
Selection should be based on the required nominal size and the connection types present on adjoining components. Proper piping alignment and support should be maintained so the adapter is not subjected to unnecessary mechanical stress after installation.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the SPG x FPT configuration.
- Confirm socket-side compatibility.
- Check male-thread compatibility.
- Maintain proper piping alignment and support.

Our PVC fitting specialists can help review nominal size, SPG x FPT configuration, PVC socket compatibility, male-thread compatibility, adjoining components, and installation requirements before you order.
Frequently Asked Questions
What is a Schedule 40 PVC SPG Female Adapter used for?
It provides a transition between a compatible PVC socket connection and a male-threaded piping component.
What does SPG mean?
SPG identifies the spigot end of the adapter, which is designed to fit into a compatible PVC socket connection.
What does FPT mean?
FPT means Female Pipe Thread and identifies the threaded connection designed to accept a compatible male pipe thread.
How is the spigot end joined?
The spigot end is designed for installation into a compatible PVC socket using appropriate PVC solvent-cement joining procedures.
What connects to the FPT end?
The FPT end accepts an appropriately sized compatible male-threaded fitting, pipe, or other piping component.
What should I confirm before ordering?
Confirm the nominal size, SPG x FPT configuration, receiving PVC socket size, male-thread compatibility, and requirements of the intended piping system.
Important Ordering & Installation Notes
- Confirm the nominal size.
- Verify the SPG x FPT configuration.
- Confirm both connection interfaces.
- Avoid excessive threaded tightening.
- Use compatible PVC joining materials and procedures.
