Description
Schedule 80 CPVC Union 2000 (SOC x FPT) EPDM
Schedule 80 CPVC Union 2000 (SOC x FPT) EPDM provides a serviceable transition between a solvent-cement socket connection and a female-threaded connection. The union configuration incorporates an EPDM sealing element and allows the connection to be separated without cutting the adjoining CPVC pipe.
The Schedule 80 CPVC Union 2000 combines a socket interface with a Female Pipe Thread connection in one removable union assembly. Selection should account for nominal size, socket compatibility, male-thread compatibility, EPDM seal compatibility, system conditions, and proper CPVC installation procedures.

Union 2000 Design
The Union 2000 design provides a removable center connection between the socket and female-threaded ends. This creates a convenient separation point for maintenance, equipment access, or piping changes.
The union should be positioned where the center joint remains accessible after installation. Proper alignment should be maintained so the fitting can be assembled and serviced without unnecessary mechanical stress.
SOC x FPT Connections
The SOC x FPT configuration combines a CPVC socket connection with a Female Pipe Thread connection. The socket accepts compatible CPVC pipe while the threaded end accepts an appropriately sized compatible male-threaded component.
Each connection should be installed using the appropriate method for its interface. Compatible CPVC solvent-cement procedures should be used on the socket side while proper threaded plastic-piping procedures should be used on the FPT side.
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 system. Inspect the sealing element whenever the union is opened for service or maintenance.
Serviceable Mixed Connection
A Schedule 80 CPVC Union 2000 SOC x FPT provides a convenient transition between solvent-cement CPVC piping and a male-threaded component. The center union joint allows future disassembly while leaving the end connections installed.
System temperature, pressure, fluid compatibility, thread compatibility, and applicable installation requirements should be reviewed before use. Proper piping support should be maintained around both ends of the union.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify SOC x FPT configuration.
- Confirm EPDM seal compatibility.
- Check male-thread compatibility.
- Avoid excessive threaded tightening.

Our piping specialists can help review nominal size, socket compatibility, male-thread compatibility, EPDM seal requirements, and installation considerations before you order.
Frequently Asked Questions
What is a Schedule 80 CPVC Union 2000 SOC x FPT used for?
It provides a serviceable transition between compatible CPVC socket piping and a male-threaded component.
What does SOC x FPT mean?
SOC x FPT means the union has one socket connection and one Female Pipe Thread connection.
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 socket and threaded end connections remain installed.
How are the two end connections installed?
The socket side uses compatible CPVC solvent-cement joining while the FPT side uses appropriate threaded plastic-piping procedures.
What should I confirm before ordering?
Confirm nominal size, SOC x FPT configuration, EPDM compatibility, mating male thread, and requirements of the intended CPVC piping system.
Important Ordering & Installation Notes
- Confirm the nominal size.
- Verify SOC x FPT configuration.
- Confirm EPDM compatibility.
- Inspect the seal before assembly.
- Use compatible CPVC joining procedures.
