Description
Schedule 80 CPVC FKM Union (Socket x Socket)
Schedule 80 CPVC FKM Union (Socket x Socket) provides a serviceable connection between compatible Schedule 80 CPVC pipe sections. The fitting uses socket connections on both ends with an FKM sealing element at the removable center union joint.
The Schedule 80 CPVC FKM Union allows the piping connection to be separated for maintenance, equipment access, or system changes without cutting adjoining CPVC pipe. Selection should account for nominal size, socket compatibility, FKM seal compatibility, system conditions, and proper CPVC solvent-cement joining procedures.

Union Design
The union design provides a removable center joint between two socket ends. This creates a convenient separation point within a compatible Schedule 80 CPVC piping run.
The fitting should be positioned where the center union joint remains accessible after installation. Proper alignment should be maintained so the joint can be assembled and serviced without unnecessary mechanical stress.
Socket Connections
The socket connections accept appropriately sized compatible CPVC pipe at both ends. These interfaces use solvent-cement joining to integrate the union into the piping system.
Pipe ends and fitting sockets should be clean and properly prepared before assembly. Compatible CPVC primer, solvent cement, insertion procedures, and required cure times should be followed.
FKM Seal
The FKM 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.
FKM compatibility should be reviewed against the fluid and operating conditions of the intended piping system. Inspect the sealing element whenever the union is opened for service.
Schedule 80 CPVC Application
A Schedule 80 CPVC FKM Union Socket x Socket provides a serviceable separation point within compatible solvent-cement CPVC piping. The center joint can be disconnected while both socket end connections remain installed.
System temperature, pressure, fluid compatibility, joining requirements, and applicable installation procedures should be reviewed for the intended application. Proper piping support should be maintained on both sides of the union.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify both socket connections.
- Confirm FKM seal compatibility.
- Provide access to the union joint.
- Maintain proper piping alignment.

Our piping specialists can help review nominal size, socket compatibility, FKM seal requirements, service access, adjoining CPVC pipe, and installation considerations before you order.
