Description
Schedule 80 CPVC Reducing Coupling (SOC)
Schedule 80 CPVC Reducing Coupling (SOC) provides a straight size transition between compatible Schedule 80 CPVC pipe sections. The fitting uses different-size socket connections on each end for solvent-cement joining within a continuous piping run.
The Schedule 80 CPVC socket reducing coupling combines two nominal pipe sizes within one compact molded fitting. Selection should account for both connection sizes, socket compatibility, piping alignment, system conditions, and proper CPVC solvent-cement joining procedures.

Reducing Coupling Design
The reducing coupling design provides an inline transition between compatible CPVC pipes of different nominal sizes. This combines the size reduction within one fitting rather than using a separate coupling and reducer.
Both connection sizes should be verified carefully before ordering. The larger and smaller ends should also be identified before installation to ensure proper piping orientation.
Socket Connections
The socket connections accept compatible CPVC pipe according to the nominal size of each end. Both interfaces are designed for solvent-cement joining within the piping run.
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.
Inline Size Transition
The inline reducing configuration changes the nominal piping size while maintaining a straight piping path. This can simplify transitions between larger and smaller compatible CPVC pipe sections.
Proper piping alignment should be maintained on both sides of the fitting. Additional support may be appropriate where a significant change in pipe size occurs.
Schedule 80 CPVC Application
A Schedule 80 CPVC Reducing Coupling provides a molded size transition for compatible CPVC piping systems. Its socket ends are intended for properly prepared solvent-cement joints.
System temperature, pressure, fluid compatibility, joining requirements, and applicable installation procedures should be reviewed for the intended application. Proper piping support should be maintained around the reduction.
Installation & Selection Considerations
- Confirm both nominal sizes.
- Verify both socket connections.
- Identify the larger connection.
- Check piping alignment before joining.
- Support both sides of the transition.

Our piping specialists can help review both nominal sizes, socket compatibility, adjoining CPVC pipe, piping orientation, and installation requirements before you order.
Frequently Asked Questions
What is a Schedule 80 CPVC Reducing Coupling used for?
It provides a straight transition between compatible CPVC pipes of different nominal sizes.
What does SOC mean?
SOC identifies a socket connection designed to accept compatible CPVC pipe for solvent-cement joining.
Does this coupling connect different pipe sizes?
Yes. A reducing coupling uses different nominal socket sizes to transition between larger and smaller CPVC pipe.
How are the socket connections installed?
The sockets are designed for compatible CPVC solvent-cement joining using appropriate preparation, joining materials, and cure procedures.
Does the fitting change piping direction?
No. The reducing coupling maintains a straight piping path while changing nominal pipe size.
What should I confirm before ordering?
Confirm both nominal connection sizes, socket configuration, adjoining CPVC pipe sizes, piping orientation, and system requirements.
Important Ordering & Installation Notes
- Confirm both nominal sizes.
- Verify both socket connections.
- Identify larger and smaller ends.
- Check alignment before installation.
- Use compatible CPVC joining procedures.
