Description
Schedule 40 PVC Cap Socket (SOC)
Schedule 40 PVC Cap Socket (SOC) provides a closed termination point for compatible PVC piping systems. The socket connection accepts appropriately sized PVC pipe and is designed for solvent-cement joining to create a permanent end closure.
The Socket cap configuration provides a simple and compact method of closing the end of a compatible Schedule 40 PVC piping run. Selection should account for nominal size, Schedule 40 PVC compatibility, adjoining pipe, solvent-cement joining requirements, intended service conditions, piping alignment, and available installation clearance.

Socket Cap Design
The socket cap configuration provides a closed-end fitting designed to terminate a compatible PVC piping run. Its single socket connection accepts appropriately sized PVC pipe and provides a compact closure at the end of the system.
This configuration is useful where a permanent pipe-end termination is required without adding multiple fittings. Nominal size, adjoining pipe, PVC compatibility, and intended service conditions should be confirmed before ordering.
Socket Connection
The socket connection accepts appropriately sized compatible PVC pipe for solvent-cement joining. Proper pipe preparation, compatible joining materials, insertion, and assembly procedures help establish the intended permanent connection.
The pipe and socket should be checked for correct nominal size and compatibility before joining. Components should be clean, properly aligned, and prepared according to the applicable PVC solvent-cement installation procedure.
Pipe-End Termination
The closed cap design terminates the end of a compatible Schedule 40 PVC piping run. Once properly solvent-cemented to the adjoining pipe, the cap becomes part of the permanent piping assembly.
The location of the cap should be considered during system planning, particularly when future piping modifications or access may be required. Adjoining piping should also be adequately supported to avoid placing unnecessary mechanical stress on the completed connection.
Compact PVC Closure
A Schedule 40 PVC Socket Cap provides a straightforward and space-efficient method of closing the end of compatible PVC pipe. Its single socket connection minimizes the number of components required for a permanent pipe termination.
Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 40 designation alone. Nominal size, PVC compatibility, joining materials, service conditions, piping support, system alignment, and applicable installation practices should all be considered during selection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the socket configuration.
- Check Schedule 40 PVC compatibility.
- Use compatible PVC solvent-cement joining materials.
- Support adjoining piping to minimize connection stress.

Our PVC fitting specialists can help review nominal size, Schedule 40 requirements, socket configuration, adjoining PVC pipe, intended service conditions, joining requirements, piping support, and available installation clearance before you order.
