Description
Schedule 80 CPVC Cap (Female Pipe Thread)
Schedule 80 CPVC Cap (Female Pipe Thread) provides a removable threaded termination for a compatible male-threaded piping component. The closed-end fitting uses a Female Pipe Thread connection to cap the end of the piping run.
The Schedule 80 CPVC threaded cap allows a threaded piping end to be closed without using a solvent-cement connection. Selection should account for nominal size, male-thread compatibility, system conditions, sealing requirements, and proper threaded plastic-piping installation procedures.

Threaded Cap Design
The threaded cap design provides a closed end for terminating a compatible male-threaded connection. Unlike a socket cap, this configuration uses threads and can be removed when service access is required.
The nominal size and mating thread type should be confirmed before installation. Proper thread engagement helps create an aligned connection without unnecessary stress on the CPVC cap.
Female Threaded Connection
The Female Pipe Thread connection accepts an appropriately sized compatible male-threaded component. The cap should be started squarely by hand to help prevent cross-threading.
Appropriate threaded plastic-piping procedures and compatible sealing materials should be used. Excessive tightening should be avoided because it can place unnecessary stress on CPVC threaded components.
Closed-End Termination
The closed-end configuration terminates the threaded piping connection without providing an additional outlet. This can be useful where future access or removal may be preferred over a permanent solvent-cement closure.
The cap should remain accessible if periodic inspection or removal is anticipated. Adjoining piping should also be properly supported to limit external loading on the threaded connection.
Schedule 80 CPVC Application
A Schedule 80 CPVC Female Pipe Thread Cap provides a threaded closure for compatible male-threaded piping. Its removable configuration can simplify maintenance or future piping modifications.
System temperature, pressure, fluid compatibility, thread compatibility, sealing materials, and applicable installation procedures should be reviewed for the intended application. Proper piping support should be maintained around the capped connection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the FPT connection.
- Confirm mating male-thread compatibility.
- Use compatible thread-sealing materials.
- Avoid excessive threaded tightening.

Our piping specialists can help review nominal size, male-thread compatibility, thread-sealing requirements, and installation considerations before you order.
Frequently Asked Questions
What is a Schedule 80 CPVC Female Pipe Thread Cap used for?
It provides a closed threaded termination for a compatible male-threaded piping component.
What does Female Pipe Thread mean?
It identifies an internally threaded connection designed to accept a compatible male pipe thread.
Can this cap be removed after installation?
Yes. The threaded connection can be removed for service when installed using appropriate threaded piping procedures.
Does this cap require solvent cement?
No. This configuration uses a Female Pipe Thread connection rather than a solvent-cement socket.
How should the cap be tightened?
The cap should be threaded on using appropriate plastic-piping procedures while avoiding excessive tightening.
What should I confirm before ordering?
Confirm nominal size, Female Pipe Thread configuration, mating male thread, sealing requirements, and system conditions.
Important Ordering & Installation Notes
- Confirm the nominal size.
- Verify the FPT connection.
- Confirm mating thread compatibility.
- Start the connection squarely.
- Avoid excessive tightening of CPVC threads.
