Description
Schedule 40 PVC Female Adapter (SOC x FPT)
Schedule 40 PVC Female Adapter (SOC x FPT) provides a straight transition between compatible Schedule 40 PVC pipe and a male-threaded piping component. The fitting combines a solvent-weld socket connection with a female pipe-thread connection in one compact PVC adapter.
The Socket x Female Pipe Thread adapter configuration is designed for applications requiring a transition from PVC piping to a compatible threaded valve, fitting, equipment connection, or other male-threaded component. Selection should account for nominal size, thread compatibility, adjoining piping components, joining requirements, service conditions, system alignment, and available installation clearance.

Socket x Female Thread Design
The Socket x Female Pipe Thread configuration combines two different connection interfaces in a single Schedule 40 PVC fitting. This allows compatible PVC pipe to transition directly to a male-threaded component without requiring a separate socket fitting and threaded transition within the same connection point.
The straight adapter configuration is useful where the piping route does not require a direction change at the transition. Nominal pipe size, mating thread size, adjoining components, system layout, and available installation space should all be confirmed before ordering.
Socket Connection
The socket connection is designed to receive appropriately sized compatible PVC pipe and forms the solvent-weld side of the adapter. The pipe and socket surfaces should be clean, properly prepared, and compatible before the applicable PVC solvent-cement joining procedure is started.
Proper joining materials and installation procedures should be used for the PVC socket connection. The pipe should be inserted fully and maintained in proper alignment during assembly, and the completed solvent-cement joint should receive the required set and cure time before the piping system is placed into service.
Female Pipe Thread Connection
The female pipe-thread connection is designed to accept a compatible male-threaded piping component of the correct nominal size and thread configuration. This provides the threaded connection interface on the opposite side of the Schedule 40 PVC socket transition.
The male-threaded component should be aligned correctly before assembly and installed using the appropriate thread-sealing practice for the piping system. Excessive tightening should be avoided because unnecessary mechanical stress can damage thermoplastic female-threaded fittings.
Socket-to-Thread Connection Transition
A Schedule 40 PVC Female Adapter (SOC x FPT) provides a compact solution when a solvent-weld PVC line must transition to a compatible male-threaded valve, fitting, equipment connection, or other piping component. The fitting combines both connection styles while maintaining a straight-through piping configuration.
Application suitability should be evaluated using the requirements of the complete piping system. Nominal size, PVC pipe compatibility, male-thread configuration, joining materials, service conditions, piping support, system alignment, and applicable installation practices should all be considered during selection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify SOC x FPT configuration.
- Confirm male-thread compatibility.
- Use appropriate PVC joining materials.
- Avoid excessive tightening of the threaded connection.

Our PVC fitting specialists can help review nominal size, Socket x Female Pipe Thread configuration, mating male-thread requirements, compatible PVC pipe, joining methods, piping layout, intended service conditions, and available installation clearance before you order.
Frequently Asked Questions
What is a Schedule 40 PVC Female Adapter used for?
It transitions between a compatible Schedule 40 PVC socket connection and a female pipe-thread connection.
What does SOC x FPT mean?
SOC x FPT identifies a Socket connection on one end and a Female Pipe Thread connection on the opposite end.
How is the socket end connected?
The socket end is solvent-cement joined to compatible PVC pipe using the appropriate PVC preparation and joining procedure.
What connects to the FPT end?
The female pipe-thread end accepts a compatible male-threaded component of the correct nominal size and thread configuration.
Should the threaded connection be overtightened?
No. Excessive tightening can place damaging mechanical stress on a thermoplastic female-threaded fitting.
What should I confirm before ordering?
Confirm nominal size, SOC x FPT configuration, PVC pipe compatibility, mating male-thread size, and installation requirements.
Important Ordering & Installation Notes
- Confirm the nominal size.
- Verify SOC x FPT configuration.
- Confirm mating thread compatibility.
- Inspect both connection ends before installation.
- Avoid excessive tightening of the threaded connection.
