Description
Schedule 80 CPVC Union 2000 (FPT) EPDM
Schedule 80 CPVC Union 2000 (FPT) EPDM provides a serviceable threaded connection between compatible male-threaded piping components. The Female Pipe Thread configuration uses threaded connections on both ends with an EPDM sealing element at the removable center union joint.
The Schedule 80 CPVC Union 2000 allows the piping connection to be separated for maintenance, equipment access, or system changes without cutting adjoining piping. Selection should account for nominal size, male-thread compatibility, EPDM seal compatibility, system conditions, and proper threaded CPVC installation procedures.

Union 2000 Design
The Union 2000 design provides a removable center joint between two female-threaded ends. This allows adjoining piping or equipment to be separated without cutting or permanently disturbing the threaded connections.
The union should be installed where sufficient access is available for future service. Proper alignment should be maintained so the threaded ends and center union joint can be assembled without unnecessary mechanical stress.
Female Threaded Connections
The Female Pipe Thread connections accept appropriately sized compatible male-threaded components at both ends. This provides a fully threaded connection while keeping the center union joint serviceable.
Threads should be clean and properly aligned before assembly. Appropriate threaded plastic-piping procedures and compatible sealing materials should be used while avoiding excessive tightening.
EPDM Seal
The EPDM sealing element provides the seal at the removable center union joint. The seal should remain clean, properly positioned, and free from visible damage during assembly.
EPDM compatibility should be reviewed against the fluid and operating conditions of the intended piping system. The sealing element should also be inspected whenever the union is opened for service.
Serviceable Threaded Connection
A Schedule 80 CPVC Union 2000 FPT provides a convenient service point in a threaded CPVC piping arrangement. The center joint can be disconnected while the threaded ends remain attached to adjoining components.
System temperature, pressure, fluid compatibility, thread compatibility, and applicable installation requirements should be reviewed before use. Proper piping support should be maintained on both sides of the union.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify both FPT connections.
- Confirm EPDM seal compatibility.
- Check male-thread compatibility.
- Avoid excessive threaded tightening.

Our piping specialists can help review nominal size, female-thread compatibility, EPDM seal requirements, adjoining threaded components, service access, and installation considerations before you order.
Frequently Asked Questions
What is a Schedule 80 CPVC Union 2000 FPT used for?
It provides a serviceable connection between compatible male-threaded piping components.
What does FPT mean?
FPT means Female Pipe Thread and identifies an internally threaded connection designed to accept a compatible male pipe thread.
What type of seal does this union use?
This Union 2000 configuration uses an EPDM sealing element at the serviceable center joint.
Can the union be disconnected after installation?
Yes. The center union joint can be separated while the threaded ends remain attached to adjoining components.
How should the threaded connections be installed?
Use appropriate threaded plastic-piping procedures and compatible sealing materials while avoiding excessive tightening.
What should I confirm before ordering?
Confirm nominal size, FPT configuration, EPDM compatibility, mating male threads, and requirements of the intended CPVC piping system.
Important Ordering & Installation Notes
- Confirm the nominal size.
- Verify both FPT connections.
- Confirm EPDM compatibility.
- Inspect the seal before assembly.
- Avoid excessive tightening of CPVC threads.
