Description
Schedule 40 PVC Counter Sunk Plug (SPG)
Schedule 40 PVC Counter Sunk Plug (SPG) provides a compact closure for compatible PVC socket connections. The spigot end fits into an appropriately sized socket for solvent-cement joining, while the countersunk plug design helps maintain a low-profile finished installation.
The Spigot countersunk plug configuration allows an open compatible socket connection to be permanently closed without adding a separate section of pipe and cap. Selection should account for nominal size, Schedule 40 PVC compatibility, receiving socket size, solvent-cement joining requirements, intended service conditions, piping alignment, and available installation clearance.

Counter Sunk Plug Design
The counter sunk plug configuration provides a closed-end fitting designed to terminate an appropriately sized compatible PVC socket connection. Its compact profile helps provide a clean termination where minimizing projection from the receiving connection is desirable.
The spigot-style design installs directly into a compatible socket without requiring an additional section of pipe and separate cap. Nominal size, receiving socket compatibility, PVC material requirements, and intended service conditions should be confirmed before ordering.
Spigot Connection
The spigot connection provides the solvent-cement interface of the plug and is intended to fit into an appropriately sized compatible PVC socket. Proper surface preparation and compatible PVC joining materials are important for establishing the intended permanent connection.
The receiving socket should be checked for correct nominal size and compatibility before assembly. Both mating surfaces should be clean, properly prepared, and aligned before completing the solvent-cement connection.
Low-Profile Socket Closure
The countersunk configuration provides a compact method of terminating an open socket connection while keeping the completed closure close to the adjoining fitting. This can be useful where surrounding installation space is limited or a reduced-profile termination is preferred.
The installation location should be considered before creating a permanent solvent-cement connection, especially where future piping modifications or access may be required. Adjoining piping and components should also be adequately supported to minimize unnecessary mechanical stress.
Compact PVC Termination
A Schedule 40 PVC Counter Sunk Plug provides a straightforward way to close an appropriately sized compatible socket connection. The single spigot interface installs directly into the receiving socket while maintaining a compact finished profile.
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 spigot configuration.
- Check Schedule 40 PVC compatibility.
- Confirm the receiving socket before installation.
- Use compatible PVC solvent-cement joining materials.

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